Help with code P 0137 (heated oxygen sensor)
Do I have to be concerned with this code? P 0137 Heated oxygen sensor (H02S) Circuit Low voltage bank 1 sensor 1. The car has not been used for 2 years and it seems to running good until I go WOT and then the engine infrequently goes into a reduced mode and I stop and turn off the car and restart it and it runs fine.2000 A4 with magnuson s/c and stainless works headers. I think my alky pump is not working. Thanks.

Most likely, you've got a bad connection on that sensor's connector or it's wires are touching the exhaust and melting. I would be concerned. No clue what you are referring to as a "alky pump" or I'm just not awake yet this morning.

The alky pump refers to the pump for my methanol system. I mention that cause I don't know if that has anything to do with the code coming during WOT. Where can I find this oxygen sensor ( is there more than one) and where do I look for fried wires ( near the headers or the back by my borla exhaust). Thanks.
Check your wiring and let us knw what you find. How many miles on the car?

There are four o2 sensors on your car. Two at the collectors where the headers meet the mid-pipe and two about halfway down the mid pipe. The one your getting an error on is at the drivers side front sensor at the collectors. There's a diagram and wiring schematics in this thread. http://forums.corvetteforum.com/c5-t...ious-help.html

Newby question. Does anybody have a picture of these sensors and the location of these sensors. I had the wires to the relay to the fuel pump below the car battery chewed up by rats. I used soder and reconnected 3 chewed wires and the fuel pump has worked fine since. Would this relay/ wires have anything to do with this code going off?
