Why do car engine go off and on when driving?
Some cars have lights that turn on lights automatically due to outside brightness
Because there's an intermittent issue which needs to be addressed. You need to have the DTCs (fault codes) read to find out which codes you have, what your active codes are, what your inactive codes are, and how many counts of each fault you have.
The check engine light goes on because there is a problem with the engine control system. Until the problem is fixed it will continue to come back on even after you clear it by disconnecting the battery.
loose battery connection, or dead battery.
Check the brake light bulbs, one may be incorrectly installed.
Check fuel filter for clogging, lines and fuel pump may be going on you. Good luck.
I would check to see if the bulbs are loose or even if wires are loose. Check the grounds to see if they are good, and be sure that there are no exposed wires, this could cause a short if they touch anything. Next, check your fuse panels. If the fuse is bad the lights should stay off but I have b...
You just install a used engine on your Lexus sc 400 why when you put it on park or drive the car accelerate on and off?
could be many problems like vacuum or wiring you may want to spend some money on hooking up your computer for a diagnostic test should only be one hour labor time for this test
So what is the problem with my stupid car with the lights on the dashlight problem?
Engine Light usually has to do with emissions if you bring it to auto zone or advanced auto they will read the code for you as long as the light is still on they should be able to help you from there. It is possible it could be an 02 sensor but there are quite a few sensors on the engine, another...
some cars are designed to turn off comp when kicked into passing gear to give you more power
well when the car shutts off it will cut the power to your accessorie of the vehicle which runs the speedometer fuel guage water temp. ect. But if you are driving turn off the key and then turn it to accessories on that's 1 extra turn right before starting point then your accessories will work wh...
Is it the taillights or the brake lights? If taillights it may be a wiring problem, If brake lights check the switch on the brake pedal
why does it matter if you're driving down a hill? At least it didn't cut off when you were driving up a hill? And I don't know why it would cut off I'm 13.
In that case, you can try setting the parking brake to see if that shuts the headlights off, as setting the parking brake typically disables daytime running lights.If a bad headlight relay is a reason that your headlights won't turn off, then the fix there is also to just replace the relay.
It is important to keep an eye out for the dashboard lights flickering because if the only symptom is a dead battery, then it could simply be that the battery has outlived its usefulness.The above symptoms could also point toward a blown fuse, bad wiring or a loose belt.
Depending on the year/make/model of your car,It may very well be that your locking Torque Converter is locking at the wrong time. If,for instance,it's a GM vehicle,there is a 4 prong plug on the side of the transmission. Un-plug this and if the problem goes away you knw you have a bad lock-up sol...
If you are on the highway...or anywhere where speeds exceed 50-55 mph then you should have it on, otherwise it doesnt matter...even if it is on, it wont be used until you hit a high enough speed.
Why does a 1993 Explorer engine cut out when first pressing on the gas and runs ruff in 1st gear and check engine will turn on but when on freeway check engine light turns off and runs fine?
sounds like a (tps) throttle position sensor. need to have it put on a scanner to check what trouble codes are stored in the ecm.
its to conserve power to start veh. with full voltage to starter headlights will come on after starting car
The cooling fan is controlled by a temperature activated switch, usually installed in the radiator. When the coolant temp rises to a preset setting the switch closes and turns on the fan.The temperature of the coolant in the engine actually goes up immediately after shutdown as the coolant is no ...
why does my door ajar alarm keep coming on and off while driving my car.
One of your door switches is probably malfunctioning. Find the switches usually on the hinge side attached to the body and use a little wd40 and move it in and out and it may start working. If not the bad one will have to be replaced.
Your oil compression is down probably... check the oil pan for rust and such.
In automobiles, a start-stop system or stop-start system automatically shuts down and restarts the internal combustion engine to reduce the amount of time the engine spends idling, thereby reducing fuel consumption and emissions.The engine restarts when the clutch is pressed prior to selecting a ...
Why does sometimes the ABS and brake lights go on and off while driving and now the fluid is low in the master cylinder of a 1994 Legend?
you should have you're brake pads checked for wear. though it may also be a leaking brake line
Why do headlights lights flicker and service light come on after driving and when putting car in park?
Have your alternator tested. They will sometimes do that when they are putting out low outputs at low rpm.
This is probably caused by leaving your Hazard Lights on, but may also be an electrical short. Have it checked by an automotive electrical technician if you have tried to turn off the Hazard Lights switch and they still stay on
There are two or more faults at work here depending on the car.If your car has a relay that runs brake lights or Tail lights one or both could be bad.ORIf your car has these items controlled by a body control module it could be bad or with this system the computer grounds the bulbs to make them w...
You check engine light is signaling to you that there is something wrong with you car. You should have your car looked at by a professional.
This could happen for different causes.1. Your battery is making contact with a surface (like the hood, seat frame or trunk battery holder.) in BMW 325 or Cadillac north-star cases.2. The positive cables from the alternation or starter are bad and making contact with the engine, manifolds or body...
They don't have automatic light features.
what kind of fluid, and what's a corsa?
If the check engine light is blinking that means that an engine cylindermisfire has been detected . You can drive it in for repair , just avoid anyrapid acceleration or deceleration because you can damage the catalyticconverter
Some cars have a time delay before it turns off. I had a Buick Park Avenue that was like that. If you open the door the radio should go off. If not, you may have a wiring problem.
is your check engine light on? and what kind of Lincoln is it? its probably becasue your car is NFG or POS
This may be due to the type of light switch or dimmer or an incorrectly connected switch.Even an unfavorable cable routing can be responsible for the glow.The afterglow issue is usually only visible after switching from old light bulbs to LEDs.
If the front lights go out when everything is turned off on a Renault Modus, this may be due to grounded wiring. Check all wiring that lead to the front lights and the connectors to the battery.
Sounds like a fuel system problem. You may need to clean and/or rebuild the carburetor.
The battery can only run for so long before it's completely drained.Malfunctioning ignition switch.When the ignition switch is worn down, there can be a loss of power to the engine because of vibration like hitting a rough patch of road.This loss of power causes the engine of the car to die while...
This light displays itself when the onboard computer system recognizes an electrical or mechanical problem with your vehicle.When the problem is fixed, the engine light does not always turn off.If it does not go off, then your engine has a problem.
Most likely your idle control solenoid is acting up making your engine run at too high of an Idle, the solenoid is stuck in hi instead of idling down when the gnition is turned off.
The warning light comes on because the charging system is failing. Have your local auto parts store test the charging system to determine the cause. They will perform the test at no cost.
Part 2 Beginning to Drive Press down fully on the clutch. Once the car is running, you will need to put the car into gear before you can start moving. Move the gear shift into first gear. Slowly lift your foot off the clutch. Begin pressing down on the accelerator. Beware of stalling. Mo...
If your engine management light comes on and off then you should have your car checked. Most cars' gauges flash when the car is initially started.First make sure that it is indeed rust on your door and not something else. Once you've determined what it is on the door it can be treated. If it is r...
The light is telling you something is wrong with the car. It cuts out because of the problem the warning light was trying to tell you was present. Take it to a mechanic and have them check to see what trouble codes the cars computer has then you know what needs repaired.
It's actually one of the most common reasons why a car jerks when accelerating.Your car's engine needs both fuel and air to do its work.A block in the fuel line or air intake can make the car jerk during acceleration as it loses one, or even both of the essential factors in keeping the engine run...
Physically check the engine oil level with the dipstick to confirm the engine is full of oil. If the engine is full, the oil level sensor or wiring to it may be at fault. If the level is low, go back to where the oil was changed and complain.
A car has a variable power setting called a throttle.So you can vary the power and thus the acceleration and maximum speed you reach.Then there is friction resisting the movement of the car, so if the faster it goes the more power is required to to make it go faster or even maintain the speed you...
This is often the result , in fuel injected cars, when there is an intake manifold vacuum leak ( i.e. loose or disconnected vacuum line, intake gasket leak , injector seal leak or many other possible leaks in the air intake system ). It is also a symptom of a faulty or maladjusted throttle positi...
The people park in driveways because a drive way is a place to park and parkways is a place were people go to work.
Parkways earned their name because they traditionally have greenery similar to that of a park. You do drive on driveways on the way to your house (especially if you have a long driveway).
The engine coolant fan can keep running after the engine is turned off in any car because the temperature gauge is in the radiator. As long as the radiator is still hot, the fan will keep running until the temperature gauge says it has cooled enough.
After parking your car, let the engine cool down with all the accessories turned off (lights, A/C, stereo), but with the engine still running for a few minutes.This allows the engine's cooling system to pump water and coolant in and around the engine, giving it ample time to cool down, and thus h...
What kind of car? More than likely a bad alternator, could also be a bad distributor or other spark related parts.
Probably not a good idea, your power steering and power brakes will not be functioning.
Replacing the battery should not have triggered the check engine light. The check engine light comes on when there is a problem with the emission system. Saying that, I would drive it for a while to see if the light does go out. If the light does not go out have the ECU scanned to retrieve the tr...
It may be from low power to the computer, a faulty fuel pump due to bad connection, or a low battery.The blower fan draws a lot of current, perhaps that is dropping the voltage suddenly and causing some electrical component in the ignition system or the anti theft system to shut down the car.The ...
You can take the "radio" fuse out and put it back in. This should work to reset eveverything.
That means you need to check the head lights. Suprisingly enough head lights on cars cause most problems. Especially on Fords.
I just got subs an amp and a deck installed in my car. When I drive about every 5-10 minutes my subs shut off and later come back on. Why is it doing this Its driving me crazy?
Overloaded circuit breaker. If you didn't beef up the electrical wiring from the battery to the new amp and subs, the original wiring is trying to supply the additional current and it just can't stand up to the load, so it "pops" the breaker ... after it cools off sufficiently, it turns itself ba...
The heat is not working because you are very low on coolant, probably because of the leak.Seems to me that it should leak worse when it is running, so I am going to assume you are talking about the coolant overflowing the reservoir, in which case goes back to you being low on coolant and the engi...
Loose connection somewhere. Bad switch maybe.
you need to replace the stop solenoid on the top of the fuel pump if it is a lucas pump. I had the same problem, but they are are fantastic price, ie £72 plus vat from main dealer, so shop around or get one from a breakers. mine started without having to bleed the system, but you might have to. d...
When the Check Engine or Service Engine Soon light starts blinking (as opposed to staying steadily illuminated), this means that a catalytic converter-damaging condition is occurring.When this Check Engine or Service Engine Soon light flashes, you should pull over safely and shut the vehicle off ...
When a car stereo cuts out and then turns back on: The problem is usually in the wiring.If the display shuts off at the same time the music cuts out, then the unit is probably losing power.Tracking down the fault can be difficult when the radio is functioning, since it actually has power at that ...
Could be a bad ABS sensor. Needs service/replacement.
IT MEANS YOU SHOULD NOT PAY the bill or Call the BBB to report THEM. IF the car was REALLY fixed - The Lights would NOT be ON.The Lights are there 4 a REASON+BUTT+I would have manual GUAGES if it was I-I would have 2 see the Manual Guage READINGS 2 believe the people-Manual is always better than ...
No it is not. But I have heard it could be damaging over time to the A/C compressor to turn off the engine with the A/C on.
Recently my amp in my car messed up it keeps going on and off when you hook it up and the protection light is on any one have any idea why it would do this?
The amp is damaged internally, the power is loose, the ground is loose, the control wire from the deck is loose.
On modern vehicles the brake system is enhanced by a vacuum operated "booster". This makes the brake pedal softer and more responsive. When the engine is turned off the engine no longer produces vacuum to supply the booster so the pedal gets hard.
If the fuel tank pressure sensor is unable to provide an accurate reading, it'll usually trigger an engine warning light.One common cause of an air leak into – or out of – the petrol tank, is through a fuel filler cap that doesn't properly seal.
Why when I am driving my car stopped at a street light the car turns off but it is still on Basically the needle was pointing at off but the engine was still on?
Many modern cards actually stop the engine if the car is stationary and restart it as you move to pull away. This saves fuel and reduces pollution.
Need more info like the year, make and model.I would suspect you have a loose or bad ground connection.
Why would your 1998 new beetle while turned off hours after driving have a fan sound coming on and off?
Your coolant temperature sensor could be malfunctioning and signaling the fans cool the engine. It is normal, especially, in hot whether for the cooling fans to come on randomly as the engine cools, but if the engine is already cold then there is an issue that needs to be addressed.
Brake & tail lights stay on after car is off and lights are not turned on.The brake light switch is probably out of adjustment, missing, or bad.When you press the brakes, the brake pedal moves away from the brake light switch, causing the brake lights to illuminate.If the switch is bad, they ...
Do all 1989 Camaros have a fan switch in the car that has to be turned on and off every time you drive and if so why?
umm i don't know of any car that has a manual fan switch the only reason someone would put one in is if the fan didn't come on by itself
If the check engine light is on, you have codes. Have the code(s) read by your local auto parts store. The codes will help you determine what's wrong.
I do not know, but it is not unusual to your vehicle. Mine does the same. Bring your spare key outside with you and when it goes off, get out, close the door and lock & unlock it to disable the alarm. If you don't have the spare key, then remove the key from the ignition while the battery is ...
Poor Connection of the Hood Latch If the car alarm keeps going off even after cleaning the hood latch sensor, the problem could be a defective hood latch connection.It can also set off false alarms because the sensor cannot respond properly to the given commands.The sensor is located near the he...
The most common reasons would be either the idle is not set properly or there is a vacuum leak. There can be other problems that can cause this also but, with the limited information in this question the problems listed above are the highest chance of what is wrong.
Do you mean the dome light, or, dash lites?In either case, there is an intermittent. Might be the light switch. or a bad fuse connection. Or, poor connection at fuse box. Or, pinched wire in the harness(This usually blows fuse, though.) If it is only the dome light, flickerring when a door is ope...
hi u could hav a leak on u vacuum pipe from u engine to the brake servo or u brake servo is faulty
You need to disconnect your battery while the car is off or until you resolve this issue.The most likely cause for the brake lights staying on is the brake light switch sticking closed.You can disconnect the plug from the brake light switch at the brake light pedal to see if the lights turn off.
Check itOn top of the brake pedal there is the shaft that connects the brake pedal to the brake switch.There could be of two problems with your tail lights being constantly on.1: The spacer between the the brake pedal switch and the shaft of the brake pedal is broke ( The brake pedal switch which...
Hello, thank you for writing in.The vehicle may be having issues with the headlight circuitry.This may mean that the sensor, photocell, body control module, replacement headlight, or a fuse/relay has failed.Something is allowing power to be sent to the headlights when the vehicle should be off.
