DTC code P1246 - should this set of a CEL?
I searched and have read up on it - generator/alternator problem possibly.
I have no electrical problems I know of - for a while last year, before the car went to storage for the winter, I had battery drain problems but I got a replacement from Ford and I figured out the problem - shorting from my XM radio. That was all addressed last fall
I just checked for codes after replacing the front O2 sensor - the Xcal2 spit out P1246 and nothing else AND there was no CEL - I was expecting no codes after switching the O2 sensor, so seeing this code was a suprise.
So, should it set off a CEL or not? Since I'm still under warranty, I think I might take it in to the dealer, but they are a bunch of tools regarding getting greasy pants and hands all over the interior - it's a PITA to clean up after them after every time I take it in.
