My dealer isn't going to tell you anything over the phone. They need the vehicle in the shop so they can scan for this code. If your dealer is inept, then go to a different dealer.

How many miles were on your truck at the time of failure?I had a reluctor wheel failure on May 1 this year on my 2014 EcoDiesel.

90,000 - 130,000 miles seem to be a very common mileage range for the tone wheel failure. Sorry to hear that you fell outside of the 8-year warranty. For sure, you got robbed. FCA should have honored the warranty for at least 10 years/200,000 miles instead of 8 years/unlimited miles.~106,500
