Check Engine Light Coming On But Now Off

Before I was able to service the car, the check engine light went off. It hasn't come back on. Should I get it checked out? What would cause it to come on and then go back off?

The check engine light comes on to alert the driver that a fault has occurred in the emission control system, if after a pre-determined number of driving cycles the problem is no longer present the powertrain control module will turn the light off, most common cause of intermittent CEL lights is a failing or as we say lazy O2 sensor in the exhaust system.

What does the spanner sign light mean on a Mitsibishi Outlander?


this usually is a maintenance reminder light the factory installs to have the driver get the car in for usually a emission component check(components that affect emissions) to make sure they are working.then they turn the light off.if maintenance has been done regularly and the check engine light(service engine soon light)hasn`t come on then you could take it to a shop that has the capability to turn off the light and have them turn the light off.some of these will come on after so many miles(kilometers) of driving just to get the car in for a service.

2005 Kia Sedona LX - check engine light keeps coming on and one code is fuel cap. replaced and still coming on. Took to dealer and they replaced Valve-Purge Cont and Canister Close V light - light stayed...


Sounds like the dealer has more work to do on the EVAP System. Smoke test the system and check Tech Service Bulletins. You could go to a local garage,it would be cheaper.

I would have the front brakes checked and from what you are telling me you may have a warped rotor I do not know how many miles are on the car some cars have a reset after the oil change has been done to turn off the check engine light but if it keeps coming on take it to autozone and they will put it on a tester for free and then you will know what needs to be done

Service soon light on, how do I reset


I purchased a hand held Code Reader at WalMart for around $100.00. The reason your Check Engine light is coming on is that you need to "Check your Engine!" If you have a service manual it will tell you what the codes mean. I had Check Engine Light on for months because I had a high idle speed of over 2,000 RPM. I kept digging on the Saturn Forum website because I could figure out what was causing the high idle. Finally after about 6 months of the annoying Check Engine Light coming on I finally figured out that I had a blown intake manifold gasket. I changed the damn thing and now the light stays off! Imagine that! The Code Reader will also reset you engine so the "Check Engine Light doesn't come back on until the computer senses that there is still a problem.
