P0315 Crank relearn varient code?
Since doing a segment swap for engine, engine diag. and system. then "Write Entire" I now have a code P0315 Crank code. I have done the Crank Relearn several times and it keeps coming back. Would having a Lingenfelter box on have anything to do with this? I am at my wits end. Its a 2012 5.3 with a 2003 P59 ecu and I am using the Lingenfelter box to convert the 58x to 24x signal. The motor only has 12k miles on it and I don't believe it to be the crank sensor. In the scanner I am showing crank sensor signal around 1400-1500. what should the signal be? Anyone else run into this and find resolution. I have seen this topic talked about but haven't seen how anyone fixed it.
Any help is appreciated.
