CEL illuminated today, scan showed P2A00
A few weeks ago I installed JBA LT headers because my OEMs were trashed, big cracks in them.
I have been in the process of e-tuning with UpRev.
Researched this issue online and I am very very concerned because it seems no one actually fixed the issue. I just found a bunch of threads that trailed off...................................................
1. It has been suggested to replace the O2 sensors. But, I don't get a "warm fuzzy" about that suggestion for a few reasons:
-everyone else that posted their P2A00 issues said that new O2s didn't fix a thing.
-I highly doubt that my functioning, 70k mile O2 sensors failed right after install. I actually didn't struggle to remove them, so they weren't "roughed-up" as may happen with sensors that are seized in the bung.
-In my years of working on vehicles, O2 sensors fail by becoming lazy with age or going full-scale output, barely moving when the engine is running. My O2s seem alive and well, the ECU is just unhappy over a period of time that it is unable to correct A/F issues.
2. It has been suggested that their is an exhaust leak. Hmmm:
- I had a massive exhaust leak in my OEMs, big gnarly cracks in both headers, tons of noise. No CEL EVER. Just horrible MPGs (about 10 in town).
- I recently went to an exhaust shop to have my crossover pipe welded and a Vibrant UQ installed, I was under the truck with the exhaust tech and we found that only the crossover pipe was leaking (black runs of soot) everything else was perfect.
- Aside from roudy exhaust noise from the JBA CBE, the truck is very quiet in the engine bay indicating that there is likely no leaks, especially compared to before.
-The other people posting about this issue also never had any luck with chasing leaks.
Anyways I am frustrated, and my research on here of other people's issues didn't find anyone who successfully resolved this issue.
Can anyone who has triumphed over this issue chime in with the solution?
I do not want to embark on a frustrating journey of constantly wrenching on the truck and throwing money, time and parts at it.
In my state we are about to not need emissions testing anymore. So.....I am thinking of just clearing the CEL every time it shows up.
Really sucks because my truck only has 70K miles on it and ran perfect prior to me futzing with it. I am a former ASE tech and have done lots of mods to my vehicles over the years, this particular truck is giving me issues I would have never anticipated.
