Hey all,
I'm havin a problem with my O2 sensors and I would like to know if anyone knows where the connecting wires run to (e.g. if to the ECM, what pin and such on my 93 Z28). I need to check for shorts or something because I'm getting a flat voltage reading on both sensors simultaneously at times while driving the car even after I changed one of the sensors. Please help and thank you.

 

The 93's have single wire O2 sensors, and the wires run only to the ECM. My Chilton's shows the connections as drivers side purple/white wire to pin D6; passenger side purple wire to pin D22.

 

Ok cool...does anyone have any idea why both of my O2s would stop working periodically while driving but both at the same time? Like, if there were a short, sometimes perhaps 1 would work and one wouldn't? Any help is appreciated.
