I recently installed a Buschur TBE with a Cat. I now have a P0137 code.

I've searched but couldn't find a definitive solution to resolve this. I installed a Vibrant O2 sensor spacer but still have the same issue. It seems the only other thing it could be is a bad O2 sensor. I find this hard to believe considering I made sure to be careful during the removal of the sensor.

Any other ideas or suggestions besides buying a new 02 sensor? My car is up for inspection and I'm trying to resolve this quickly. Thanks.

 

Turn the code off in your ECU ala tephra mods? What is the code for EVAP or EGR? I can't remember

 

Did you reset the code after you installed the spacer?

 

+1^^^ disconnect and reconnect the battery.

 

Heated oxygen sensor (rear) circuit low voltage

Thanks for the replies everyone. I did reset the battery after the install. The check engine light came back after about 15 mins of driving around town.

 

My guess is you may have damaged rear O2 wiring during install.

This is not a cat efficiency code its for the heater circuit of the sensor so is wiring getting stretched, damaged, or depinned from connector it would throw code

 

Easiest thing to to do is to just turn it off in your ECU....I'm sure someone in your area has a tactrix cable and some knowledge on how to do it.

 

I know how fusterating this coad really is, I had the same code about a month ago, I replaced the rear o2 sensor and cleared the code with my access port (witch is junk) and it drove fine for a day! The next day I got a new. Code (p0420) something to d o with the front o2! So im gonna change that next!

So the O2 spacer will not fix this code? I used the insert with the smallest hole for the spacer.

 

Bump for any more suggestions....

 

Looking for any more ideas. I checked the wiring and everything looks fine.

 

that will not work on a obd2 vehicle

 

Not true, read up a little more on things before making a comment like that.

 

It looks like my only option for now is to try replacing the O2 sensor with a new one and see what happens. I'm trying to hunt down the cheapest option on a replacement sensor.
