P0315 2010 Ford Fusion Code - Crankshaft Position System Variation Not Learned
Quick Answer
The Powertrain Control Module (PCM) is unable to learn and correct for mechanical inaccuracies in crankshaft pulse wheel tooth spacing. Common causes include Faulty Crankshaft Position (CKP), Crankshaft Position (CKP) sensor harness is open or shorted, Crankshaft Position (CKP) sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
