Hi all I got a cel checked it at autozone with their code reader it was p0138. I cleared it and it came back after I got home. I plugged my flashpro in and it said p2270. I cannot find any info on that code. Can the two code readers be different and is p0138 the same as p2270? I got a snippet somewhere that p2270 is o2 related. Thanks

im gonna guess your o2 sensor in the cat is bad.

 

Thank you for that!
