engine check light came on then went off??
ok the other day the missus was picking the kids up from school and noticed the check engine warning light was on! the car seemed to be running fine no missfires or anything and then when the car was stopped to pick my son up after it was restarted the engine light was off! any ideas?? the car is a v6 vs calais!

Go around all the sensor plugs and make sure they are secure. Could be that the O2 sensors are starting to go. Check to see if an error code was logged.
im thinking either sensor on the way out or faulty ignition coil could also be just old wireing to! dont think it would be coil pack as no rough idle??Originally Posted by 4BDN_VR
yeah faulty o2 sensor was the first thing to spring to mind!
only human......
check the codes. when the light comes on then goes off it means a code has been logged

As TheForgotten says, check error codes. No point having stabs in the dark about what it could be - could be hundreds of things. There is a how-to that describes the process.
no worries fellas will check the codes see whats loged cheers for the help!

at least the missus correctly identified it as an engine light....
every time mine goes on she [the missus] says the "oil light came on" which almost always gives me heart attack.
Oxy sensor, champ. They commonly fail and give an engine warning light here and there.
If its not working, you're not hitting it hard enough.

Jackson, i notice you're a newB so I'll just point out that this thread is nearly 2 years old .. not sure where you dug it from but its probably been fixed by now.
Maybe CXCXCXCXCV can come back and tell us what it was ?
Mine did the same thing. Buy 3 cans (about $10ea) of throttle cleaner and spray out your throttle etc. Clean up your egr valve and injectors and if you can get to the O2 sensors, carefully take them out and clean them. You will be suprised how much built-up carbon pours out which is soaking up your oxygen and throwing off your sensors. You car will run smoother and use less fuel.

Damn that carbon soaking up all my oxygen.....
Just hand me the pliers.
wouldnt suprise me if CXCX had faulty oxy sensors given his current fuel usage problems, however Im sure he has since replaced them and earthed them correctly.
I wonder if CX will check in to let us know what went so wrong so long ago?
Just thought id add my two cents but thread digging isn't always bad, sometimes a thread will cover some very usefull information or some of the info will be incomplete and someone will fill in the gaps or add a little extra its refreshing in a way, dont some of you long time members get sick of answering the same question from scratch? isnt it easier when someone uses information already available to discuss there new problem?
Ive had this problem for ages. Any updates as to whether or not it was the o2 sensor?
Exhaust Guru
Just do a code check and find out. In the How To section.
Code 76. Leaves it wide open for anything to do with air and fuel.
somtimes couldnt these things be somthing even more simple like a faulty globe or somthing ( only said this cause no-one else has and from i kno it is possible?)
Exhaust Guru
Code 76 points directly at the O2 sensor. Cut the purple wire on the RH sensor, (on the loom side of the plug) and reset the PCM, take it for a drive and check the codes again. Cutting the wire won't really hurt anything. It was a Holden fix back in the VS days anyway.
If I cut the wire on the loom side, and get a new sensor, it will still be cut, shouldnt I cut it on the sensor side?
If its not going to make matter worse, I will give it a chop.
Exhaust Guru
Which ever side you cut it, it doesn't matter, but the problem is in the circuit, not the sensor. If you get a new sensor and the loom side isn't cut, the problem will still be there.
Personalised Comodore number plates Victoria
Hi all. Just wondering if you guys can give me an estimate of what I should ask for these plates, as a guy down the street keeps pestering me for them.
