Engine/Transmission (1998.5 - 2002) APPS 1693 and 1022 code Need help

OK I spent quite a bit of time before I posted this searching what could be the problem so sorry if this is a repost, also its long. It seems there were parts of my problem in all the posts but no solution has worked. I have a 2k 3500. I have an airdog on it with Edge box, stage two injectors. Constant fuel pressure to pump of 15 lbs, has never changed, gauge right on top of steering column. Been hard to start for a week or so before this, used to fire on first crank. Drove it to the airport, engine stumbling like it was fighting a head wind. It started to cut out more, CEL came on and temp guauge started acting erratic. Parked for few days while away. Upon my return home check engine light still on, temp guage and oil pressure gauge go to zero, truck cutting out and not wanting to rev especially above 1800 but does not die. Code P1693 displayed. Once home check out the forums. Disconnect batteries clean post try pedal recalibrate. No good. Order TPPS from Timbo, install, do not set voltage (because torx broke off in nut! WOW), and Timbo stated all I would have is a slight dead pedal issue and I needed to get the truck on the road, calibrate pedal. Would recalibrate voltage later. Drove the truck approximately a mile on test run worked okay. Took the truck to work an hour later same problem! Stopped at autozone code read P1022 low TPS voltage. Limped it home and now for some reason I'm thinking crank sensor. To add insult to injury, we've been in the middle of a drought. The weekend that my truck dies we get 7 to 14 inches of SNOW!!! Help!

So with another OBD II tool additional codes were revealed. P 0606, P 0122, P 0237, P 0117, and P 0112. Anyone wanna try?

As a guess, either you have a loose\bad connection somehwere or the ECM has issues.


P0122 (M) Throttle Position Sensor Voltage Low Throttle position sensor input below the acceptable
voltage range.

P0122 (M) Accelerator Position Sensor (APPS)
Signal Voltage Too Low
APPS voltage input below the minimum acceptable
voltage.


P0112 (M) Intake Air Temp Sensor Voltage Low Intake air (charge) temperature sensor input below the
minimum acceptable voltage.


P0117 (M) ECT Sensor Voltage Too Low Engine coolant temperature sensor input below the
minimum acceptable voltage.


P0237 (M) Map Sensor Voltage Too Low MAP sensor voltage input below the minimum acceptable
voltage.


P0606 (M) ECM Failure ECM Internal fault condition detected.
