The Wiring book ( page 85 if you have the surpa wiring manual ) I have shows that the Cali spec rear heated O2 sensor goes to the ECU via 30A. The other main O2 sensors tap into 47B and 48B

If you have a rear sub O2 sensor ( meaning your cali-spec ) ALL of you O2 sensors should be the same 4wire sensors. You sure your harness isnt hacked or not the correct one? I have not seen a cali spec supra with any 1 wire O2 sensors.

Xutech....lol. No comment.


Anyways....if you have a rear O2 in the mid-pipe, than your cali spec and all of your O2 wires are 4-wire. It can not be 1 wire.

Maybe you have a midpipe from a cali car, but your supra is NOT a cali spec. Would explain why the front O2's are 1 wire.


I'd say Xutech mucked ur shit up ;)
