My car reads no codes except for P0137 low voltage bank 1 sensor 2

The UR test pipe is designed to have a mechanical fix for the rear o2 sensor, if i add one, two or three foulers on top of the mechanical fix as well, which # of foulers would give me the right fix without giving me a low activity CEL?

Does anyone have this problem and corrected it in this manner. Any help is appreciated thx!

 

You shouldn't be having that issue. I have had one on my car for a long time and never had a cell. I have installed that pipe on 2 other cars and no cells either.

 

I've had this issue on both the test pipe and HFC's from UR. It only seems to happen when I don't let the exhaust warm up well before getting on it at the track.

Both my test pipe and hfc are very early UR pieces though... not sure how it works on the new ones.

 

I thought the P0137 code was for the front o2 in the downpipe? Not the one in the cat...

 

i was wrong, i thought the evo had 3 sensors, i put on one fouler in the rear...didnt work, put on the two this morning...so far so good..lets pray it stays gone

 

no it's the secondary cat.

 

I have both as well like you, and both early versions. I run the catted version for STU and the TP all other times. Never a code in 8K miles. Knock on wood...eeek

 

i have this same problem
