Different voltage at ecu that at sensor. WHAT?
Ok I have run wires to my ecu from my 4 wire o2 sensor and I am getting no to little voltage at the ecu. But i get like .8 - .7 volts at the o2 sensor. Could it be the wire I am using? I have bigger gauge wire. I don't think that would be a problem. Any help on this? Thanks.

There shouldn't be that much of a voltage drop across a wire. If so your ecu would get the wrong voltage as well. You must have a bad connection somewhere.

Man I don't know what to do. I have this o2 code that is really pissing me off. Does anybody know how to hook up the o2 sensor for a OBD0 Car that was switched over to OBD1 with a hasport harness. I am steaming cuz I can get it to work. I have been working since 3 o'clock. It is now 9.

O2 sensor wiring question. Hasport harness
I know this is in the wrong forum but i need more people to look at this. Ok i have a new question. Where is sam hell is D14. I am really pissed off right now and I need some freaking help. Thanks. Has anyone switched there car from obd0 to obd1 with the hasport harness. For some reason i cant get the o2 code to go away. Heres what I have. DX crx to MPFI. D16z6 engine. hasport shorty harness for the obd0 to obd1 conversion. I have directly wired the o2 sensor up to the ecu but that didn't work. Does the o2 have to read the temp sensor, tps, and the coolent temp. I have the heater code gone so that can't be it. could someone tell me how to wire this would be good.

Re:O2 sensor wiring question. Hasport harness
you're using a 4-wire o2?
did you use shielded wire?
did you use shielded wire?

I think it does.
