Alliant AP63415 Camshaft Position Sensor (CMP) for 2008-2010 6.4L Powerstroke

Restore reliable starting, smooth operation, and proper engine timing in your 2008–2010 6.4L Powerstroke with the Alliant Power AP63415 Camshaft Position Sensor. This direct-fit, OEM-quality replacement delivers the precise camshaft position and speed signal your Powertrain Control Module (PCM) needs for accurate fuel injection timing and overall engine performance.

Why the CMP Sensor Matters

The CMP sensor is a critical magnetic pickup mounted on the left front of the engine block. It reads a peg on the camshaft target wheel once per revolution and works together with the crankshaft position sensor to tell the PCM exact piston position and which bank is firing. Without a clean CMP signal, the engine will not start or will run poorly.

A failing sensor is a common cause of:

• No-start or hard-start conditions
• Intermittent stalling
• Rough idle or misfires
• Diagnostic trouble codes P0340 (CMP Circuit Malfunction) and P0341 (CMP Circuit Performance)
