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 Fleece Performance Fuel Rail Pressure (FRP) Sensor Wiring Harness (Part # FPE-HAR-DMAX-RP-0610) provides a direct replacement for damaged, oil-soaked, or heat-fatigued factory sensor pigtails.

Constant engine vibration and extreme under-hood heat cycles frequently compromise the factory fuel rail pressure sensor connector, leading to intermittent signal voltage loss, engine misfires, rough idles, and limp-mode triggering. Fabricated in-house using automated precision wire cutting and terminal crimping processes, Fleece replacement harnesses ensure flawless electrical connectivity with zero core charge.

Key Features & Benefits

• Direct OE Replacement: Direct replacement for GM Part Number 97366636, ensuring proper plug-and-play compatibility with factory sensors.
• Automated Precision Terminals: Manufactured in-house with automated machinery for uniform crimp integrity and maximum pull-out resistance against engine vibration.
• High-Temperature Insulation: Built using automotive-grade TXL cross-linked wire and tight rubber weather-pack seals to resist oil and moisture degradation.
• Cures Common Sensor Faults: Eliminates erratic FRP sensor voltage drops, engine hesitation, and random rail pressure diagnostic trouble codes (DTCs).
• Zero Core Charge: Brand-new outright replacement wiring harness requiring no core deposit or core return shipping.
