Need to restore a clean cam signal and get your 7.3L Powerstroke running right again? The Walker Camshaft Position Sensor is a direct-fit replacement designed to restore accurate camshaft position data when the factory sensor starts to fail or send inconsistent signals. When the CMP sensor fails, it can cause hard starts, stalling, a rough idle, loss of power, or a no-start condition because the ECU loses its ability to properly time fuel injection. This sensor brings back the critical timing signal, so your truck starts easier, runs smoother, and stays reliable under load.

Built to OE fit, form, and function standards, the Walker CMP sensor features durable internal electronics engineered to withstand extreme heat, vibration, and constant cycling in the engine bay. The housing is designed to resist oil exposure, moisture, and contamination that commonly degrade sensor performance over time, while maintaining stable signal output from the camshaft trigger system. Each unit is fully tested to OE specifications to ensure accurate communication with the ECU, delivering consistent engine timing, dependable drivability, and long-term durability in demanding diesel applications.
