Shooting wires for No Bus condition, tested O2 sensors.No cross wire shorts. Grounds are ground, sensor grounds only ground when connected to PCM, wires test fine. No Codes.
Manual says should read 0.1V for 2 min during open loop, then fluctuates between 0.1-0.9V once warmed up for closed loop.
Mine both read 0.01V-0V when cold.
Once warmed up:
Upstream (grey) fluctuates between 0.15V-0.96V
Downstream (black) fluctuates between 0.24V-1.04V
Are these values within tolerance? Calling out the sensors as bad? A sign of too lean/rich fuel?
Warmed up, upstream seems close to correct, downstream seems swayed just a bit.
0.01V to no volts for the first two minutes doesn't seem right at all though.
