Check engine light came on. I checked all fluids and fusses. Everything is good there. Why does my light stay on?

Disconnect battery.Wait ten minutes and reconnect

Your vehicle may have an "oil level" sensor built into the oil pan. If so, and the sensor is bad, the dash will constantly tell you that the engine needs more oil even if it does not. Checking the oil with the dipstick, a minute after the engine has been turned off on level ground is always the best way to check your oil. Try scanning the vehicles computer systems to see if there are any fault codes. The warning light may also be on a timer that just needs to be reset. The "Check Oil" light should be separate from the engine oil pressure warning light. As long as the engine oil pressure light stays off, you should be ok. Checking the oil pressure with a manual gauge would be a good idea as well.

Have you check the battery and the connection to the starter. If they our OK check your main line fuss link . Make sure you battery post our good and clean . If you have a meter you need 12.2 volt to start the engine any thing less it will not start . But if its not turning over it sounds more like the battery is bad .

Thats ur check engine light. check all ur fluids oil/transmission/coolant or antifreeze. If light stays on then see a mechanic, and they have a machine that pugs into ur car and tells you whats wrong

do you know what the code is? if the check light comes on. please have a parts store scan it for codes it is free

Hello,

There is a lot of things that cause a engine lite to stay on.

Here is just a few things, that will have engine light stay on:

Service is due, some cars have that automatically do this when time for regular service.

Breaks, Some cars have a sensor that after a certain range on your pads, it triggers the service Light.

Oil Low, or water/antifreeze low.

Emission problem, Like fuel filter needs replacing or possible 02 sensor not working ( part of your Cadillac converter)

Battery not fulling charging, or alternator not putting out proper amps. etc,,

This list can go on and on, most the time if you have low oil, or break issue, there is separate warning lights for that.


Here is what I think, sometimes when you have something wrong with your car, if you checked your oil level, water/antifreeze level, breaks seem good, and all your other fluids are good, and your car is running good and as normal, what best to do, is take it in and have them put it on there computer, this will tell you if there is something your over looking, by normally a code that comes up on there system. Sometimes the code will come up on there computer and not on your dash warning lights. Auto Zone, normally can do this for free with there hand held computer and tell you what comes up and what to check out. And all Garages if everything is ok, can with computer turn your engine light off if everything is ok. But for sure get it checked, and don't just assume it is a faulty engine light coming on, most the time there is a reason. Thanks Mike

A engine light can come on for numerous reason if it comes on and stays on take it to autozone and they will run a diagnostics check for free. and give you a print out of what could be wrong. Its probably something simple like a sensor or something need to be replaced. But you can check your fluids like oil, transmission fluid, and water to be safe

The check engine light is on because the computer has detected a fault in the system.It could be a sensor,wiring or bad connection.You have to get the codes read to find out what could be causing the problem.Most parts stores will do this for no fee at all.Hope this helps.Good luck.

no fuel injector pulse check computer fusses

sounds like you have burnt through the insulation of two or more cables and they are fused together in the loom .Start looking from radio back
