Is your truck bogging, misfiring, or throwing a check engine light? The Walker Camshaft Position (CMP) Sensor is the exact replacement you need to restore accurate camshaft position feedback to your ECM and keep your engine firing right. When this sensor fails, it disrupts timing signals, leading to performance issues, reduced fuel economy, and erratic behavior. Installing this CMP sensor restores dependable timing accuracy to your diesel, so your truck runs smoothly, responsively, and reliably under load.

Engineered and tested to meet or exceed OE specifications, this sensor features high‑quality internal circuitry that delivers a consistent signal output throughout the part's life. The robust housing and precision electronics are designed for typical diesel-engine conditions, heat, vibration, and repeated thermal cycling, while the factory‑style connector ensures a secure, weather‑resistant fit. Every unit is 100% tested before sale, giving you confidence in its long‑term durability and signal integrity
