So I started to work on my truck to get her on the road and I started it up the engine light is on, I checked codes and to my suprise I have a list:
P0107
P1762
P1754
P1749
P0483
P0243
P0480
P0642

Anyone know if these could just be caused by one sensor? truck runs and drives good.

thanks

 

P0107 = MAP Sensor low
P1762 = Gov Pressure Sensor offset
P1754 = TTVA
P1749 = TTVA Sensor low
P0483 = Cooling Fan Speed
P0243 = Turbo Wastegate Soleniod A Malfunction
P0480 = Cooling Fan 1 Control
P0642 = Sensor Ref Voltage 1 low

The sensors operate on 5VDC (Sensor Ref Voltage) which is supplied by the ECM.
A lot of sensors would cry when the the ref voltage is low.
Looked like you have the ref voltage issue (P0642).
You have a short somewhere that pull down the 5V circuit.
Check for wiring harness damage for the cooling fan. Not uncommon problem.
Check for wiring harness damage near/above the AC compressor. Not uncommon problem.
It could be the ECM, the wiring/connection of the 5V circuits.
I would reset/clear all the codes and drive it to see if they come back again.

 

I've cleared codes and they come on right away with out the motor even running, what color wire am I looking for that could be broken?

 

Clear the codes.
Disconnect the connector for the fan clutch, located at the bottom of the shrould.
And try.
You don't want to see P0642.

Have fun.

 

Looking for wiring rubbing, bare wiring touching each other or touch the ground, broken etc.
