    Keep Throwing Code P0315??

    Anyone know why I keep throwing the code P0315?? It is for Crankshaft Position System Variation Not Learned. I have done the relearn several times and even replaced the sensor. It seems to happen once every 2 or 3 months. Any ideas???

    you have to go to the dealership to get that code to go away. i got it on everything i owned. from my experience i have driven araund forever with the code and saw no ill affects but eventually got it cleared by dealer just so i wouldn't have to see the light. but its like 75 dollars.

    I've got a new tune from Nelson getting ready to go in for the FLT Level 5 and will reset it then. I can get the code reset (my dad has an auto shop) but my issue was that it keeps happening and I wasn't sure why. Hopefully this will be the last time.
