What is code P0315.....?
 

Not sure what this code means
P0315 Crankshaft Position (CKP) System Variation Not Learned. I tried removing it with autotap and it will not remove the code. Any ideas? :confused:


Here is a good site for defining codes

did you just install the tune or another pcm. if so you will need to do a relearn procedure for it.

man thanks i was just about to go there. :hail:

Not a passkey problem, its a Crankshaft Position (CKP) System Variation Not Learned. Just dont know how to correct it. unless this procdure corrects this too?

EDIT: Nelson pcm has been installed for just about 2 months, and now im getting this code.

This is just a nuisance Virus. Has no impact on your computer what so ever.

EFIlive has a crankshaft position relearn program,you basicly clear all engine codes and follow the instructions on the screen.That takes care of the problem.Or you can go to someone with a Tech tool to do the samething.

I dont have EFI live. Will my AT1 cable from autotap with with efi live? How about a PCM reset?

Would the dealership have to do this? What other shops would have this tech tool? I got the 0315 code after picking my truck up from the tranny shop....

Most likely the dealership will have to do this with their TECH II.
