Code PO315
Forum Members: Your Help is needed.
Today, I started up my 2007 C6 and I noticed the CEL. I have a PO315, which I believe refers to the crankshaft position sensor problem. The car runs flawless - no hicups of any kind and has been running fine for a long time and the engine has not been modded in over a year and a half. I disconnected the battery for 30 minutes or so and that didn't help. Before I consider taking the car to the stealership, what do you guys think I should do? I could probably take it to AutoZone. Maybe they could erase the CEL or the CEL could come back on? Thanks. |
You need to have the crank position relearned.
