When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

I have a 2001 Mitsubishi Montero sport, the check engine light is on, it's at 112000 miles, flawless car as far as I know, ran a diagnostics and got code P0400, what do you think it could be? I don't feel anything except it shakes a tad during idle and idles anywhere from 500k to 800k rpm. If you have any idea please let me know.

2001 Volkswagon Gti- engin light came on car drove

your computer can have those codes stored in memory although theres nothing actually wrong. you can unplug your battery for about five minutes then hook it back up this should free the codes out of the system.also if youve traveled more than 30,000 miles id relpace the plugs in do a complete tune up.

Engine light is on but no apparent problems. oil OK. antifreeze OK. checked spark plug wires in front. had serviced last week. drove 250 miles to Tucson. drove a couple of days around Tucson---no problem...

you should be able to cycle key 3 times quickly to on position and the odometer will show codes. have codes read and find out what issue is it may be something minor but its best to know before it gets more costly

I've had the same problem on my 2001. It turned out to be the battery. Apparently the voltage had dropped to the point that the computer began to malfunction. I'd first go to a battery shop and have it checked under load before looking for other solutions.
