What is the failure mode of the sensor?
I have a PLX Devices M-200 unit and for the past week or so, when I start the car (from either cold or hot), the gauge reads 14.67 to start with, then within about 30-40 seconds, climbs up through the teens and then shows "Lean" for the rest of the drive.
I am about 100% sure this is an instrumentation problem, not an actual lean condition - the car runs fine and the plugs look good.
The display and sensor are about 2 years old but have fairly low miles on them - maybe a couple thousand. I don't drive the car that much.
So is this consistent with the failure mode of a Bosch 5-wire heated O2 sensor? I don't want to throw $80 at something that doesn't fix the problem...:wall:
Thanks,
Pete
