CazzaVR 0 Posted January 29, 2007 Unplugged the cps the other day when I was changing the water pump. Will this mean the car is now in limp mode, even though I plugged it back in? Car's not too nice to drive! If so, how can I reset the ecu? Can I simply unplug the loom near the aux water pump? Cheers! Quote Share this post Link to post Share on other sites
vr6storm 0 Posted January 29, 2007 I wouldn't have thought so Andy...........afterall when you replace the CPS you just plug it in and off you go,no other procedure etc Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted January 29, 2007 With the power off, no! I would unplug the ECU plug rather than the multipin plug on the engine block as that doesn't actually disconnect it from the power supply, it just disconnects the engine sensors and sensor grounds / injectors etc. Quote Share this post Link to post Share on other sites
tonedef 9 Posted January 29, 2007 I can't see that unplugging the CPS would cause any problem but then I did unplug the engine multiplug Saturday just to get a bit more access and aftewards the engine was running rough. I went through the ECU reset proceedure in the Knowledge Base and it's all OK again, in fact as soon as the battery had been disconnected at the start of the reset it was fine again.

CazzaVR 0 Posted January 29, 2007 OK, thanks chaps. Will just try the ecu reset in the Wiki as a precaution. Quote Share this post Link to post Share on other sites
CazzaVR 0 Posted January 29, 2007 What about the TPS? Forgot to plug this back in after cleaning the TB, and ran the car a couple of times before realising. Quote Share this post Link to post Share on other sites
