Need to fix hard starts, random stalling, or a no-start issue on your 7.3L Powerstroke? The Walker Camshaft Position Sensor is a direct replacement that restores an accurate camshaft position sensor signal when your factory unit starts to fail. The camshaft position sensor plays a critical role in engine timing. When the signal drops, your ECU can’t properly control fuel injection, leading to poor performance, misfires, or a truck that won’t run at all. This sensor brings that timing signal back so your engine runs smoothly, starts consistently, and stays reliable.

Built to meet OE fit, form, and function, the Walker CMP sensor uses high-quality internal components engineered to maintain precise signal output under extreme heat, vibration, and continuous engine operation. The design is made to handle common failure points like heat cycling, weakened internal magnets, and long-term wear that can cause signal loss over time. The durable housing is built to resist oil contamination and engine bay exposure, and each unit is fully tested to ensure accurate communication with the ECU for dependable timing control, consistent performance, and long service life.
