Question about Pontiac Grand Prix
P0315 is a code that indicates and error from the crankshaft position sensor. Typically it is the sensor itself and not an issue with the crankshaft. The sensor itself runs from $30 to $40, but replacement may not be a DIY job unless you're comfortable under a car and removing pulleys from the front of the engine.

Appears to be the code for the camshaft position sensor, or cam sensor circuit. Around $35-45.00 for the part at an auto parts store. Have the part replaced. And take it from there. Might be a good thing to replace the spark plugs and wires too.
