If the light was flashing when it came on, then it means your engine is misfiring.

A solid light can mean anything.

This light comes on when the computer detects a fault of some sort in its diagnostic tests. If it keeps detecting this issue, the light will remain off. If the light turns off, then it has detected that the issue may no longer be present.

In order to find out what the exact reason was for your light, You need to have your car computer scanned to retrieve the code that the computer would have stored when the light triggered. Most garages will do this free of charge. The code will tell you what may have caused the light to initially go

It could be a variety of things that can cause the light to come on. the most common thing to cause it to come on is an O2 sensor malfunctioning. however your best bet is to get it checked with your local mechanic to verify what is causing it to come on.

You can reset the lamp by disconnecting the battery for five seconds.

If you haven't diagnosed and repaired the problem, I don't recommend you reset the lamp. The problem may be intermittent and the stored trouble code may be all there is to try to determine the nature of the problem.

In the event you haven't repaired the issue, I'd recommend having the engine and transmission diagnostic trouble codes read and reporting them here. I can then advise you how to proceed with diagnosis and repair.

I hoep help you (remember rated this help) Good luck.

There is a yellow engine light on what does that mean is it just a service engine light


If the light is on and is in the classic "engine" shape, then yes, it is a service engine light. All it means is that something is wrong, somewhere on your car, not specifically with the engine (althoug it might be)

Service engine soon light is flashing


Have the car scanned for the code's origin. This could mean that the engine will not work as well as it should, and could cause driveability isues.

A constant service engine soon light means that a hard code exists. A flashing light means that an intermittent code exists, but it could become a hard code very quickly.
