Kevin Bacon 5 Posted May 17, 2003 Does anyone know much about the VR6 O2 Sensor? I think mine is dead but I haven't got VAG-COM to check, so I was hoping someone might know the restitance values when healthy as I do have a multimeter. The only thing that confuses me is there is a black 4 pin connector on the rear engine mount and also a white 3 pin connector, which one is the lambda connector?

Kevin Bacon 5 Posted May 19, 2003 Cheers for the offer Scott mate but Vince told me how to check it over the weekend. Basically, you prod a multimeter probe into the far right lead of the black plug (signal) and the other probe to ground. With engine hot and idling the voltage should fluctaute between 0 and 1 volt, if you have no signal or a steady voltage then the lamda is dead. Mine does as the man says, so back to the drawing board! The car just feels down on power and gets coarser and louder the more you push it. Dunno what's up with it. How did you aquire your VAG-COm out of interest? From Ross-tech? I ordered it and got to the payment stage and was put off by the having to fax my credit card number across bit. They need some E-commerce technology me thinks! Cheers Kev 94 VR6 Quote Share this post Link to post Share on other sites
