GMC Troubleshooting Questions? Ask a Mechanic for Answers
can you tell me the year and make and model and engine size ?
with the key ON at bank 2 sensor 2 does the pink show 12 volts ans does the orange/white show a good ground ?
you replaced # ***** in this picture ?
see if those 2 check out
when you get your meter
this chat will stay open
when its acting up check those 2 wires
if those 2 wires check out and the O2 sensor is brand new it is usually a defective O2 sensor or the other 2 wires from the O2 sensor to the computer or the computer itself
what brand O2 sensor did you use ?
bosh is usually a decent one to use
did the bosh when installed make it any better or worse ? or the same ?
i would be more apt to think it is one of those 2 wires from the O2 to the computer or the computer at this point
there is not not else to cause this code
the o2 itself
the wiring from the o2 to the computer
the computer itself
when the fault is there the light will be on and when the fault is not the light will go off
