You will need to have this scanned. That car has the older OBD system that will give you a basic code when scanned and further testing of the advised area may be needed. From my own experience, if it is on for approx 5 minutes once the engine is warmed up, it usually is the oxygen sensor. Again, you will need have it scanned for the code to be sure of what to verify.

SOURCE: 1990 Buick Century 3.3L Check Engine Light comes on, stalls.

Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.

SOURCE: 2003 AUDI Quattro 3.0 check engine light(MIL) stays on

Before you do anything else you are just going to have to read the codes. So buy the maintance book at autozone,locate the little juction box on the fire wall and jump the terminals with a little wire. Then of course sit in the drivers seat turn on the key(do not start) and read the blinks. Then you will know what the problem is.

SOURCE: 1992 Mitsubishi lancer GLXI check engine light sensor appear

Well the sensors are reporting a failure in the engine/transmission. So either they are right or wrong has to be assessed by the nature of the alarms or sensor faliure, but the problem remains, hence if all primary steps of investigation start by hooking up to a PC specially built to rectify such problems. This facility is available at most of the gas service stations/centers..................sodeep

Check engine Light (emission Control System)

wait about a day and let the car dry out some. Then reset the check engine light by unhooking the negative cable from the battery for 15 minutes or more. Hook it back up and see if the cel even comes back on. It probably wont but if it does, go to parts store and get the code and go from there. Shouldnt be a big deal, car is prob ok. Just get code if it does happen to come back on and reveal the year, make and model of the car and the code. But you need to reset the light 1st to see if it comes back on.

2007 CRV check engine light goes on and off

Do not pay for a scan. Take the car to a store that offers free scans and tell them you need the codes stored in history and any pending codes. Then post the codes here for help with diagnosis. Don't rep, ace parts until you have a good diagnosis.

Does the check engine light come on when you turn the ignition on, before trying to crank the engine? If it does not, then the ecu is in need of repair. Try leaving the ignition on, without cranking the engine, for a few minutes, to see if the check engine light eventually comes on. If it does come back on, the ecu is going bad.

"Service" light just started coming on over the weekend. It comes on, stays on for about 5-10 minutes, then goes off. The other lights - check engine (I think), oil, etc. - come on when I turn on the car...

The light is set to light by milage and it is to let you know that the next service is due. This is reset by removing the rubber grommet that is to the left lower corner of the speedometer and depress the reset button.

Check engine light comes on and goes off after about 5 minutes of driving. All fluid levels check out fine. Motor will knock if light stays on for any longer than 5 minutes

sdYour fluid levels can be OK and you can still not be getting oil up to the valves, rocker arms and push rods. I would suggest taking the valve covers off and see if oil is lubricating the above. Please let me know if I can be of any further help.

sounds like a fuel filter or more likely a fuel pump fault.low fuel transfer pressure,possibly a dealer would be cheaper than a diy repair unless you have the diagnosis correct.
