i bought my car not knowing the previous owner had put a p28 ecu in it added a couple wires for the oxygen sensor and now the sensor is bad. can't figure out what oxygen sensor i need cause people keep giving me the run around. i need a wiring diagram so i can change it back to normal. (so it's not hacked up)

can anybody help me out with a site for a diagram? or just buying a haynes manual would be easiest..?

anybody?

 

nobody? nobody will help?

 

If you're wanting to revert to a single wire unheated O2 sensor the white wire is the one you want.
