    My truck was driving great, and didn't have any issues until I started her up Sunday morning. The Check Engine Light came on, and the Traction Control Off light was displayed immediately. The truck drives, but has a major loss of power, and feels like I'm pulling a heavy goose neck in a V6. Took it to a parts store & they coded the MAF Sensor as needing to be replaced. Put in a new MAF Sensor, and disconnected the ground for 20 minutes, but the problem still persists.

    Now I have the following codes and was hoping to get some help with what could cause so many error codes.
    -> P0037
    -> P0057
    -> P0102
    -> P1613
    -> P1614

    All connections look good, wiring harness good, and have done all servicing at the dealer. Thought it might be the Air Injection Control Driver #89581-60010, but that's just an expensive guess. Has anyone had this happen, or any ideas?
    Thx

    Breaking it down a bit, i see both banks of 02 sensors, both bank secondary air controller, and the MAF. The 02 sensors should throw you into a limp mode, which is why you feel all the missing power.

    It isnt unheard of to buy a new part that doesn't function. I might have started looking @ the secondary air injection system. they make a bypass kit for it if your emissions arent so stringent.

    Putting those 5 things together though. its an airflow through the system issue, MAF could be yelling because the burn ratio isnt measuring right from the 02, because the air injection isnt working properly.

    Just a guess though.

    Only use a OEM MAF sensor.

    Update. Thankfully my due diligence saved me $4k at the dealer, or $400 for the bypass wiring harness. I had narrowed it down to bank 2 sensor, and told the dealer so they didn't have to trouble shoot a whole bunch. Apparently, a rodent chewed the one wire just enough for it to fall, hit the manifold causing it to shorting out the sensor, and then blowing a fuse. Simple fix, and a little over $200 later my beast is now back.
