Is your truck cranking but not starting, randomly dying, or throwing timing-related codes? The Walker Crankshaft Position Sensor restores accurate crankshaft signal data so your ECM can properly control fuel injection and engine timing. When this sensor fails, your truck can lose sync between the crank and cam signals, leading to hard starts, no-start conditions, poor performance, or erratic engine behavior. Replacing it brings your Cummins back to life with smoother operation and consistent performance you can trust.

Built to meet or exceed OEM specifications, this sensor features high-quality internal components that withstand extreme heat cycles, vibration, and long-term engine wear. It’s 100% engineered and tested to ensure accurate signal output and dependable operation in harsh diesel environments. Working alongside the camshaft sensor, it helps maintain precise timing and fuel delivery, improving efficiency, drivability, and overall engine reliability. Designed as a direct-fit replacement, it installs easily and delivers OE-level performance mile after mile
