Throwing codes P0037, P0137
 

I recently installed my new cat-less down-pipe and ran into a issue removing the o2 sensor from stock down-pipe. The o2 at the bell-mouth of turbo is in and secure its the o2 sensor following the first cat on stock down-pipe. If anyone could please give me the technical name for which o2 is it i need replaced it would be great. I was confused looking at websites for o2 sensors because they have like 2 downstream o2 sensors.

It's called a downstream O2 sensor. Also called secondary or second. Try rockauto.com they should have what you need. Just make sure the connector is male and not female (the O2 connector has to clip into the harness, hence male whereas the harness is the female).

That will clear both codes?

If your secondary isn't working then it will at least clear the p0037. I'm not sure about the p0137.

More Information for BOSCH 15371 look right to you?

You'll probably need an AP to disable the p0137. Or am I on crack again? I thought those popped up when we removed a cat?

No that has a female connector plug.
