You'll have to run diagnostics on it. An analyzer is connected to the car through a cable and it analyzes the computer and spits out codes that tell you why the light is on. Auto shops do this, or you can purchase a home diagnostic analyzer at an auto parts store.

Warning light check engine light turns on, sometimes after 10-20 minutes drive. The engine is perfectly OK. Indicator light is off after the car has "rested" during the night.


You may have a sensor malfunction. Have a mechanic run the codes and see if there are any stored in the computer. Just because the engine runs OK now does not mean it will continue to do so. The reason the light goes off after the vehicle has set over night may be due to the vehicle not sensing the issue after the long passage of time, until you begin driving again.

I won a 2005 Volkswagon Beetle, My check engine light came on on way to work? Should I be driving it. My manual is at home. Thanks very much for assistance


well yes if it is still safe to drive you may continue to drive it but you should get it looked at to see what codes your ecu (cars computer it puttting out ) you can do this for free at autozone they have a free code reading service takes only a few min and they can also print you out a slip telling you whats the reasons are the code is coming up aka check engine light on.

that all being said when the light comes on it means the cars ecu had detected a electronic signal from a sensor that was above or below a preset threshold e.g. you could have faulty o2 sensor it wont normally affect the drivabillity but you will burn more gas as your ecu dont know how to ajust the air and gas mixture therefore resulting in poor gas milage ect but all that being said you most likely just have a sensor that has failed most are easy to replace by yourself

hey hope it helps if so 4 thumbs up would be great have a great day

My truck has 381000 miles and it runs perfect i drive it every day and would trust it to go anywhere the check engine light is on and reading low fuel pressure sensor i dont know if it is the fuel pump or...


i would try the gas cap first. if the gas cap isnt on tight or wright that will make the check engine light come on and so forth. but check your gas cap first. hope this helps!

Check Engine Light On. Vehicle runs and drives fine.


A vehicle check engine light can come on for a variety of reasons. Many times your vehicle will run perfectly fine even with a sensor that is bad. You still want to get these fixed due to the fact that it can cause lower gas mileage or in time cause problems with your vehicle. If you go to Auto zone they can plug a computer into your car for free and tell you what is bad. Once those problems are fixed the same place can check your vehicle again and clear the check engine light.

Engine light just started to come on. The oil level checks out.


check the gas cap...i"ve found that a loose cap will set off the check light...if you dont have a computer to recall or reset the codes i believe it"ll just go away after you drive it for a couple days on its on once corrected.

Check engine light remains ON


You need to go somewhere that can read the code from your computer that will tell you the problem. Some auto parts stores have this ability such as auto zone and others.
