Question

2012 Ford F250 6.7L with engine code P200C, how can I fix this?

Answer 1

P200C Diesel Particulate filter overtemperature Bank 1

This code conditon does not set by itself there should be other set along with it. If this code is set with P200C and P200E , the fix is to replace the EGT sensor. You may just qualify for a warranty that Ford has produced just for this code condtion.
