Engine light on, getting an error read P0546 , Sensor 1 Bank 1 showing "Exhaust temp., censor circuit high". Can't reset, error remains.
Truck doesn't run or behave differently. Any suggestions?
My truck is a 2011 with 98.500 miles on it, 1500 miles before I'm out on any kind of warranty coverage. Might this be an issue that is possibly covered by the 100k miles power train warranty?

 

Entirely possible. Call the dealer and ask.

 

Just was educated in a call wioth the dealer. Power train warranty is 60 months or 100kmls. Guess with a 2011 I am out of that one lol ...
