P0137 help please
 

Hello. I am getting a p0137 low voltage. I am currently on a catless exhaust and header setup( jdl uel, mxp exhaust) ecutek tuned at drift office. I didn't get this code until 3-4 months after tune. I'm sure it's not the tune. The cel will come on for 30 mins to a couple hours and switch off for a day or two. I made sure the connectors were fitted in the right spots and o2 seems to be in place. If it was a faulty o2 I feel like the cel wouldn't disappear on its own. Any ideas would be greatly appreciated. Could the o2 be bad after first 18k miles?

I live in wa also where it's wet and 36-60 degrees daily

P0137 comes on and usually regards something to do with the O2 sensor bung, it's harmless and you can just disable it in romraider. If you have an O2 spacer you can get rid of it, and just disable t on romraider

Did you get a solution to this? I am having the same problem under similar circumstances.

It's the PNW ...... most likely mold, mildew and moss growing inside the ECU.

how are your fuel trims and measured AFR? If they are out of whack by quite a bit you may have a leak in the exhaust
