Anyone in the Spring/Houston area know where I can get my truck scanned? I got my tune from nelson about 3 weeks ago and after about 200 miles I get the light. I got it checked at Autozone with an ODBII scanner and got this code:

P2A04 O2 Sensor Circuit Range/Performance.

Allen says he is not sure what it could be since he deleted my rear O2s, so he asked me if I could get it read by a different scanner. If anyone in the area has one or knows of a place I could get it checked i would appreciated.
Trying to not have to pay a lot to get it done if i can.

 

I can scan it and long it with efilive. We will just have to meet up some time. I live in North Shore, right off Beltway and Wallisville(close to I-10). Let me know if you are intrested.

 

I just took the cats off an 05 ECSB 5.3L and got the same P2A04 code. It is listed in this document towards the bottom of page 8. http://redhat3.admarkonline.com/~sup...install-46.pdf

It is O2 Sensor Circ Range/Perf Bank 2 Sensor 2. It is not one of the NORMAL codes turned off when you delete rear O2s. I have never seen this code in the 2 tuner packages I use to edit PCMs.
