Check Engine Light/ Wrench and Drive to Clean Filter
well today after i filled my truck up with fuel upon starting it up the check engine light came on...i took it to advance and read the codes throws 2 codes. a P246C- AUX Emission Control
and a P2453- particulate matter trap diff.press.sensor circuit.
it keeps saying drive to clean filter and i have ran half a tank of fuel out of it and it keeps coming back on, it has even went to reduced engine power.
the check engine light is on and the little wrench is on the display.
im going to take it to a dealer in the morning and see what the heck it could be im assuming one of the half a dozen sensors in the exhaust. this is the first ive had trouble with the truck and it has 18,000 miles on it. im hoping my dpf back exhaust wont hurt me on this but i dont feel like putting stock back on after fighting with the thing all day.
