bank 2 upstream o2 sensor showing 1.27V, even with no sensor plugged in
whats going on with this?
bank 2 o2 sensor stuck at 1.27V with no sensor, with any sensor. I suspect a short but wouldn't know where to begin. code p0152
voltage never changes from 1.27V no matter rpm, drive condition etc.
stats collected from torque app, and elm obd2 dongle.
what ive tried:
1:swapping bank 1 and 2 sensors.
2:tried a spare known good, used sensor.
3:disconnecting sensor and reading live output.
should I try another pcm, scared to short it out too.
