#1 of 4 2001 Outback P0032 O2 sensor heater high output.
Jan 16, 2008 (5:01 pm)
I've been told that it is highly unlikely that the O2 sensor is bad. Any ideas on where to start the troubleshooting of this CEL. Any ideas on what color the wires are from the ECM that I need to check the voltage of?? (B134) No. 23 and (B134) No. 22. Also where is the ECM located in this vehicle?? Any help would be appreciated.

what makes you think it's not the O2?

The CEL code P0032 means (Front oxygen (A/F) sensor heater circuit high input). If the O2 sensor itself is bad than I should have read P0130, P0131, P0132, P0133, or a P0135 fault.

Actually that seems like the code not for O2 but for the MAF or MAP.
