02 cummins codes p1693 p0122 p1475 HELP
Engine revs erratically when throttled then doesnt rev then jumps around low power. Im getting code P1693 P0122 P1475
Ive replaced the APPS sensor reset and calabrated the APPS to the ECM, tested the complete wiring harness, checked fuel pressure (good) still nothing! I need all the help i can get! Truck does not have any upgrades or tuners. |
Thats sort of a random list of codes, the only one that would make sense is the P0122 (Throttle position sensor low voltage)
The P1963 usually means theres some other codes behind it I believe? Did you read these codes off the dash or with a code reader? As for the P1475 is just a fan relay |
I agree! still need some help!
|
crank sensor maybe?
|
I dont know. I dont want to guess and send a ton of cash and not fix a thing.
|
I'm thinking crank/cam sensor as well.

sort of a common problem it sounds like |
Is there a way to test them.

usauly youll have a code for the crank sensor i know ive had the code and i replaced mine its good now but i have had problems where i would run good then loose power then it would come back it threw codes for a injection pump timing tps sensor and i replaced my fuel filter bc it was way dirty and cleared codes and its been good.

I havent had a crank sensor code.
