OBD2 codes
well i scanned my truck again, and now i have the actual codes to post, i dont really understand the description the computer give me, so i figured someone else would know. I do know that one is an O2 sensor, and the other has something to do with the EGR valve.
The codes are
P1401
P0141
thanks in advance

P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
That's the rear sensor behind the cat. The code is telling you the heater circuit isn't working so it could be as simple as a blown fuse or wiring problem.. or the sensor could be bad.
P1401 - DPFE Circuit High Input

are you sure about the the O2 sensor, because my truck doesnt have one after the cat, it has 2 in the exhaust manifold and one right in front of the cat and that is all it has.
