Engineered specifically for 2006 through 2010 Chevrolet Silverado and GMC Sierra 2500HD/3500 trucks powered by the 6.6L Duramax V8 turbo diesel engine (LBZ and LMM codes), the Bosch Original Equipment Fuel Rail Pressure Sensor (Part # 0281002971 / 12639277) mounts directly to the fuel rail to measure internal common-rail pressure in real-time. As the original equipment manufacturer (OEM) for the high-pressure common rail fuel system, Bosch builds this sensor to exacting factory specifications.

Over time, continuous exposure to extreme common-rail pressure spikes and thermal cycling can cause sensor drift or signal failure. A failing rail pressure sensor triggers check engine lights, hard starting, poor fuel economy, rough idle, or unexpected engine derates. Replacing the faulty sensor with an authentic Bosch OE unit restores dependable fuel management with zero core charge.
