Title: Check engine light
Post by: chrisr on 11 June 2017, 12:12:36

On a fast, fully loaded trip back from North Devon to Surrey yesterday my check engine light came on while accelerating away from a set of lights. The car ran and still seems to be running normally. I disconnected the battery to try and clear the light but no luck. The pedal trick did not work. Any ideas? 2.2 2002 petrol auto.
Thanks.

Does it go out after a restart?, after a few hours that is. Mine was a cam sensor. If you do need one, buy only from a main GM dealer and get it yourself. :y

I had that on my 2.6 V6; a dose of Cataclean, a tank of Shell V-Power and an Italian tune-up clered it! I did get a code, though, telling me that the N/S cat efficiency was low.

You need to get the codes read, before taking any action.

Yep, no point guessing. It could be anything at this stage. Get it to an OBDII code reader and see what it's reporting.

Desmond cam sensor can cause this as well... Cross checked with a code reader and lots of random gearbox codes ;)

If it is the cam sensor I have a known good used GM one off my breaker

*IF* it is a cam sensor - and don't randomly change parts until it is proven via a code reader - don't bother with pattern or 2nd hand. Go to a dealer, and buy a real one from a real dealer.
