2006 4.0 auto, Cranks, but No Start.

[6.2]

having an issue where the truck will not start. Cranks over just fine, I did check the fuel cuttoff switch, its not that.

I did go through a lot of snow today, I cleaned as much out as I could from the engine bay and had my truck running afterwards for about 45 minutes letting it melt/dry.

Went to start it later to go to my sisters place, does nothing but crank.

Codes that came up were P0068, and P1100.

P0068 Throttle Position (TP) Sensor Inconsistent with MAF Sensor

Checked the wires for MAF and checked MAF itself, all seemed fine. I didnt check the wires for the TPS (got dark and my fingers were not having anymore of the cold)

P1100 Mass Air Flow (MAF) Sensor Circuit Intermittent

again, checked wiring all looked fine, but looks can be deceiving when snow/water is involved.



My question, is are these two things in conjuction enough to make the truck have a no start condition? if so, any ideas if the TPS wiring all looks fine?

I'm going to try and fine a warm space to put it in to fully melt it, but that might not be possible since it doesnt start.

i would shoot it with starting fluid and see if it starts, so you know if you have fuel/spark.

i seem to remember that my truck will not start but will run with the maf unplugged. might try tapping on that tps with something, might be "stuck" wide open.

will try that tomorrow

figured I would update this. finally had time to check the things related to the codes, turns out the TPS was bad, snow got into it, and froze up and broke the sensor. Thankfully it didnt break the tab on the throttle body. New TPS and melted the ice out of the throttle body and it fired up.
