DTC P0134. A/F sensor no activity HELP

Im throwing a primary 02 sensor code.

its showing 0 volts..

now.. the wires were crossed somehow on my hybrid harness so it was wired wrong at first.. but now its all straitened out and its still showing 0 volts..

i jumped the pins on the hybrid harness to see if i could get 5 volts out of it on hondata but still 0 volts...

i found this on another thread on K20a.org.. its the exact same problem.

1) On the O2 sensor it reads 0.00 volts and -37.0 mA. The SO2 it reads 4.08 volts and I don't even have a secondary O2 sensor. I can't figure out what is wrong, Help!! Code P1166 Heated Oxygen sensor, is that the primary O2 sensor?

2) On the Sensors window, what is Fuel Status? It says Open-Error on mine.

3) My air to fuel stays at 10.70:1 and never moves.

is theyre anything inside the ECU that couldve gotten damaged when the wires were crossed?

i have recently tested the wire comming directly out of the ECU for the o2 sensor with a voltmeter and its not putting out 5 volts...

You may have damaged the ecu. Open it and smel the inside of hte ecu..if it smells burned, then it will need to be replaced. Even if it does not smell burned it may be damaged and need to be replaced.

is there any way someone could repair it if that is the case?

Sure that you load the correct .KAL

I was mounted a PRB-KPRO on european civic typeR and load the kal from PRA-Euro-civic.kal, error code P1034 displays on Kmanager.

If the ecu is damaged, it cannot be repaired.

Where does it display voltage going to primary o2 sensor? I just hooked up KPRO..I doubt mine is fried...assuming its not fried..would a steady reading of 10.7 indicate bad o2 sensor? My should be destroyed by now. I just wanted to confirm that a steady 10.7 no mater what fuel config change would mean bad sensor.

It could mean a bad sensor, bad wiring or a damaged ecu.

There is no voltage display of the primary O2, as it is currrent and not voltage based.
