I had 3.73 gears installed and when I reflashed my VMP tune to adjust for the gear change this code popped up. I flashed it back to the tune I had for the stock gears and the code so far hasn't reappeared. Does VMP have to tune for the gear change? I was always under the impression that I could do it straight from the tuner.

I flashed back to stock and then reflashed again with the VMP tune to reflect the 3.73 change. Went for a 15 mile drive and no code. Hopefully that worked. Thanks.

Reviving an old thread. I had an H pipe installed on my car, and HP tuners (via laptop) turned off the O2 sensors. Now, have this code. I clear it and it comes back. Any ideas?
I have not done a CAM reset, but thinking of doing it and putting drive cycles on it.

Figured it out.... just turn off the code in the computer. Light has stayed off now that we turned off the reading.
