Walker Camshaft Position Sensor (CMP) 17-21 GM 6.6L Duramax L5P

Is your Duramax throwing cam/crank correlation codes, running rough at idle, or struggling with misfires and hesitation due to poor timing data? The Walker Camshaft Position Sensor restores accurate camshaft position feedback to your engine’s control module, enabling it to properly time fuel injection and combustion events. When this sensor fails, critical timing information is lost, leading to poor performance, rough running, and intermittent drivability issues. Replacing it with this direct‑fit sensor restores smoother power delivery, improved throttle response, and reliable operation mile after mile. Built to meet or exceed OEM standards, this sensor features high‑quality internal components and a rugged housing engineered to withstand heat, vibration, and long‑term engine service. Designed for an exact OE‑style fit and connector, it installs easily and delivers a consistent, accurate signal output to your engine’s computer. Engineered and tested for reliability, it ensures dependable performance in demanding diesel environments, helping maintain proper timing control and optimal combustion efficiency under all conditions.
