Engine Light after Piggy Back
Well I had a piggy back installed a few weeks ago and just today I had an engine come on. I do have a OBD 2 reader and it shows the code P2A0B. I haven't been able to find out what this means but I have reset it and it hasn't come back.
I'm thinking it may have been a O2 sensor perhaps? Is anyone able to find out what this code is?

I can't remember where but I saw someone had a similar issue with one of the connections coming loose. Since they are in such hard to reach places it hard to make sure they are in there unless you really listen for a clicking sound. See if you can trace the wires and just double check they are clipped properly on both sides
