Gentlemen, new to the forum and Dodge trucks for that matter. Just got a 99 2500 long bed QC 5spd. CEL on with code of P0122 Pedal position sensor/TPS. You guys have any suggestions for me? Ive cleared it a dozen times but it keeps coming back. Any help is appreciated.

 

are you having any other symptoms?? and have you tried the reset procedure(s)??

else it may be time to put on a new APPS.... p/n is 53031576.

 

no other symtoms, I was just gonna run it till it takes a shat. I unhooked the batteries overnight and reset the CPU, is that reset procedure you are talking about? I am only getting about 12 mpg around town, is that normal? Also just pulled the codes again and got P0122 again but included P1690 Manufacturer Control Auxillary Inputs/Auxillary Outputs whatever the hell that is.

 

It's odd that you have no other symptoms than the P0122 code.

P1690-CKP SENSOR DOES NOT AGREE WITH ECM CKP
SENSOR

perhaps your crankshaft position sensor is the real problem here...


here's one APPS reset procedure... there is another one but I don't have the link to it.
