Title: Fault codes not listed?
Post by: MrDJ on 25 August 2010, 12:02:05

Removed coolant temp sensor lead - found couldn't get to sensor without a ramp so reconnected and now have these codes.

1-5 Coolant temperature sensor Voltage high
3-4 ??
9-3 ??

1-5 fair enough as I have a new sensor anyway but what are the other 2?

don't know much about cars but googling seems to point to EGR being same area as CTS so ive prob done something :(

No idea why imob is playing up mind..

Yeah, connector for EGR very adjacent to where you've been doing battle, and the wiring shares a bit of conduit with the temp sensors' wiring IIRC.

Removing the scuttle may make progress with this job considerably easier, I think. Don't have ours (the missus's) here to have a look I'm afraid.

PS, fill in the Location bit of your profile, someone may be near enough and willing to lend a hand.  :)

PPS 93 may be cam-sensor related according to info in this link: http://www.vauxhallownersnetwork.co.uk/archive/index.php/t-179882.html  :-/

Again, you may have knocked the connector while reaching over the engine (just at the front of the black 'Ecotec' strip)

Knocked a wire off the EGR when messing with coolant temp sensor.

All codes seem to have cleared once put back on - immob code flagging was odd :)
