I searched this thread first and then many others to figure out what to do. Still brainstorming

I didn't see anyone on here who has thrown the P0037 twice as far as having it show up on an OBDII scan. <----Please show me if there has been. I took it to Autozone and I was a little shocked to to see this code come up 2 times. I may have messed up during the exhaust install because I installed one of my rear O2 sensors in front of my race pipe and one behind it. I have checked my wires to every extent and they all are good. I have a dual O2 sim hooked up, it's on but obviously doesn't work. My main concern is why P0037 came up twice...any ideas?

 

Bump for suggestions

 

Sorry to dig up an old thread but I've spent an entire day looking for a solution to the P0037 code. I got this after replacing the O2 from the P0138 code. I saw something about a heater? What do I need to fix to get rid of this code?

Thanks

 

Twice? P0037 is a two trip code. You get 1 pending and 1 actual, which shows as two codes for P0037.

 

hmm... i dont know abuor twice, but i got this code and dont know how to fix it. And Scott, your car looks great!

 

Grrr, I just got a P0037 tonight after I spent a total of $660 CAD replacing both rear o2 sensors plus my Evap canister and Valve after my car went on a code-throwing rampage this month. I've read through some of the old posts on P0037, but no definitive fix has been ID'ed. So I wonder:

1. Could the use of some anti-seize compound caused contamination on the new sensors, and would this necessite buying another one from the stealership? (i.e. does one only get one shot at installing an o2 sensor cleanly, or risk making a $200 mistake?)

2. Assuming connections are good, does the possibility exist that maybe the stealership has to do an idle re-learn in order to get rid of the SES light?
