BLU-BY-U

I've popped this code a few times over the last 2 months. Again today on the way back to work.

What is the description of the code and what should I do to eliminate it?

Car is 2002 Z06 with a cam, pulley, xpipe w/cats, borla catback, and ls1edit.

Any help appreciated.

Thanks.

P0137 Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 1 Sensor 2

P0137 is O2 low voltage bank 1 sensor 2 which translated means the driver side rear O2 may have detected a lean condition. Since it is an intermittent condition, it could mean a wiring/connector problem. You might want to try swapping the rear O2 sensors from one side to the other and see if you throw a P0157 instead.

thanks fellas.

What does the PCM do to the timing/fuel tables when it senses this condition? Will it pull timing or dump fuel?

Maybe I should have it replaced or have the wiring checked out. The car has been a little down on power.

Check the Heated O2 sensor fuses. I am not looking at my shop manual right now but I remember that certain Heated O2 sensor codes can be caused by a blown fuse. I am not sure if your code is related to fuses but it is worth a look.

thanks RB, I'll give that a try
