Camaros SS - DTC P0137 H02S circuit low voltage error

mfinos · Post by **mfinos** » Sun May 13, 2007 10:19 am

When I run my Camaro SS on the predator, I contiually get the P0137 and P0157 error codes. The car is stock except an SLP air lid. Car is an auto. I have run the car for a few weeks, seems to run OK on the predator, although I do not want to run any further until I know that everything is OK. Is the car running lean, should I be modifying some parameters to solve this? Any help would be great....

FYI - no error codes without predator tune.

Just looking for some additional information:
P0137 - O2 sensor low voltage error.

Have you made any modifications to that circuit? Cut a wire, done any soldering or splices or moved the sensor?

I know you said that the codes only occur on the Predator tune but there may be some sensitivity in the O2 circuit that only shows up when on the modified tune.

I really have not touched anything else on the car, everything else is stock.

Predator revision?
Have you modified the tune at all?

Nope, just running the tune right out of the box.

Any other help you can give me on this one?

Not exactly sure what you are asking. I looked on my predator and it says Predator 2.12. Is that what you need?

Ok, that is the revision.
Have you tried reinstalling the stock tune to see if these issues still happen?

Thanks

Yes, I am back on stock tune now, the error codes do not appear in stock tune.

Strange, I will have to look into this.

Thanks
