Where is the O2 sensor?

Post by bronson1111 » Tue Apr 26, 2011 2:37 pm

I have a 2002 Volvo S80 T6. I am trying to figure out the location of the O2 sensor near the head gasket. Does anyone have a diagram or a map of the O2 sensor locations?


Thank you!
Bronson

You are referring to the upstream (Pre cat) sensors then? There are two, one for each bank. Follow the exhaust pipes from the turbos back towards the cats and you cant miss them, they are right on the top of the pipe about (I guess) 1.5-2ft away from the motor.
