Walker Camshaft Position Sensor 01-04 GM 6.6L Duramax LB7

Is your engine misfiring, losing power, or throwing timing‑related codes? The Walker Camshaft Position (CMP) Sensor delivers the precise camshaft rotation data your engine’s control module (ECM) needs to accurately control fuel injection and ignition timing. When a CMP sensor goes bad, your engine can hesitate, idle roughly, or run inefficiently, leading to reduced performance and drivability issues. Installing this direct‑fit replacement restores proper timing feedback, helping your engine start smoother, run more consistently, and respond more confidently under load, whether you’re towing, hauling, or just cruising the highway. Built for durability where it matters most, the Walker CMP Sensor is made with high‑quality, heat‑resistant components designed to withstand extreme temperature swings, vibration, and contamination under the hood. Its rugged housing protects the internal sensing element from premature wear, while OE‑level design and testing ensure proper fit and reliable signal accuracy. This dependable sensor delivers long‑lasting performance you can trust in both everyday driving and demanding diesel or gas applications.
