The Accelerator pedal just stops working. I have replaced, Accelerator Pedal sensor twice, Pigtail to Pedal, ECM, and i still cant figure it out! Fuel Pressure, and CP3 test great. Pedal will work, then just stop working on take off.
I have no idea what to do or where to check next....Could it be the PCM?
what else could it be??
Codes
p2133
p2139
p2140
they all are about the pedal, and i cant figure it out neither can my shop
anyone knows, 812-821-7277 you can call me or texting is faster

 

check all your grounds and clean them would be the first advice i would give.

 

do you have a programmer on the box?

 

check out the attached file

codes indicate it is sensor #3 on the peddle

trace the harness from the peddle back to the next connector and check it with an ohm meter. all three sensors should read the same but #2 will read backwards.

if all is fine then it is probably the throttle actuator control module

 

my sensors dont read the same..
app1 - .7
app2 - 4.0
app3 - 4.4

and i still can figure it, thats y i replaced pedal sensor twice

i had EFI Live on it, then had them reflash compter to stock, then i replaced computer, and its still doing it without EFI on it

 

where is the throttle actuator control module located?

 

i think it is integrated into the ECM. do you have any tools to log/monitor the throttle position? EFI Live? see what the ECM is seeing
