Truck in signature throwing:

P0107
P0642
P1749

Yesterday it was throwing P0480, now that's gone and it's throwing P0483.

These are key-on codes, meaning I clear them and they come right back.

I did a search here and found one person posting with the same combination of codes, but the thread was closed years ago and had no resolution.

I checked the MAP sensor and everything seemed good there (5V ref good, boost pressure is displaying on the quad), did not get to the other 3. These all popped up at the same time, after passing a car on the highway last night.

Symptoms are hanging upshifts and occassional erratic idle (jumps from 750 to 800 for less than a second and drops back down). No overheating to correlate with the fan codes.

Any help anybody could lend would be appreciated, I'm at a loss with this :bang
 
Signature is missing! Did you clean all your battery connections? Bad grounds reap havoc on a CR.
 
Didn't mean to abandon thread, posting fix for future searches. The fan caught the clutch harness and shredded it. I replaced the clutch and shifting cleared up immediately, codes cleared after a couple drive cycles.
