Default Check engine light P1416 and P0161

I read the posting on in this forum on check engine light problems. I reset my DTC codes which had P1416H and P0161H to see if it would come back. It did with P0161H C and P1416 C. I have an extended warranty (few months left), so I made an appointment to have the dealer check it.

My question is what words of wisdom do you folks have so when I take it to the dealers that 1) it gets covered by warranty and 2) they don't try to tell me I need something more than is necessary.

While I checked the DTC codes I also have U1160H and U1000H and U1064H. Any advise on those codes? I read the code descriptions from the links other have posted, but it doesn't explain what the actual problems are.

P0161 Heated Oxygen Sensor (HO2S) Heater Circuit Bank 2 Sensor 2

P1416 AIR System Bank 2

U1064 Loss of Communications with BCM

U1160 Loss of Communications with LDCM

U1000 - appears to general RFA (Remote Function Actuation)

Any advise would be appreciated.

You can find the troubleshooting info for 2001 powertrain codes here. It should give you some idea what you (or your dealer) are up against.

GL!

Ahh, P1416, your AIR check valve is most likely stuck. It is BURIED behind the intake manifold and takes alot of swearing to get to.
