Did the big recall 2.5 weeks ago within a week I started getting the p0191 code. Cleared the code a few times and would eventually come back on within a short time. It’s been under 10 degrees for 2 weeks or longer.
Took it back in they replaced the FRP sensor. The light was off while in there shop. Sat outside a few hours (8 degrees) I started it up and it instantly came on, cleared code and instantly came back on again. They did ask me if it has any additives in it. I did put some power service in it, I don’t remember if it was before or after this code popped up. Could the power service be the whole issue? Brought it home going to drive it a few weeks to get the power service out before taking it back in....
