Hey guys, CEL just set on my dads 2010 3500, He has DPF, EGR, and EGR Cooler delete. Smarty Jr 67ME. He was on his way into Ohio (about 230 miles) and cel came on, checked it with the smarty and it was P0132. Which is position 1 HO2S right? His truck has no O2 sensors on it. He has had this setup for the past 10K miles with no problems. Any help would be appreciated Thanks

 

Is it running a turbo back or just a dpf delete pipe?

 

It has a MBRP turbo back 5" straight pipe

 

I've looked around different sites, and it says that this code (bank 1, sensor 1) commonly is caused by faulty wiring. You may have a cut or fray in the harness somewhere. Look for the most simple problem first. Other than that, not too sure. I wish I could help more. I'm surprised no one else has piped in with a little more experience on this. But the last time I got a code like this on my truck was from an actual bad O2 sensor.

 

im in the same boat but with a different code mine is a po471 cant figure it out im about to pull the light and call it code free lmao and also any time it rains or alot of moisture and even wash my truck my water in fuel light comes on
