Heavy Duty Truck Throttle Position Sensor Replacement for Cummins Volvo Mack International Williams Controls | OEM 134734 85101350 1697269C91

Product Overview The 134734 / 85101350 / 1697269C91 Throttle Position Sensor (TPS) is a heavy-duty potentiometer-driven signaling module engineered as a premium aftermarket replacement for Williams Controls electronic pedal assemblies and major global commercial truck fleets. Mounted directly onto the throttle pedal mechanism inside the cabin, this high-precision sensor measures the exact angle and deflection velocity of the driver’s acceleration input. It seamlessly translates mechanical foot pressure into dynamic electrical voltage arrays for the Engine Control Unit (ECU), restoring factory-sharp acceleration response, stable cruising logistics, and fuel-injection optimization.

Mack Trucks Direct fitment for Mack Vision, Granite, CH, and CX series regional distribution and vocational transport vocational builds. Cummins Heavy-Duty Engines Comprehensive integration with Cummins ISX, ISM, N14, and M11 diesel platforms managed via matching electrical harness grids. Navistar / International Trucks Fits classic and modern semi-truck variants requiring standard 1697269C91/2607117C91 throttle switch positioning. Ford Heavy Trucks Fits corresponding commercial cargo and F-Series industrial vocational mediums operating matching engine platforms. Performance Benefits Instant Acceleration Correction: Instantly cures sluggish engine throttle response, dead spots during pedal travel, and unexpected engine dropouts to idle. Rugged Structural Shielding: Features a high-density polymer shell and robust structural cover plates to isolate delicate internal dual-track wipers from under-dash dirt, floor moisture, and continuous friction wear. OEM-Spec Signal Linearity: Manufactured to match original resistance ranges precisely, ensuring seamless integration with factory computers without creating check engine warning loop codes (P0121/P0122 series). Maintenance Tip: In long-haul logistics fleets, classic symptoms of a failing 134734 throttle sensor include sudden “Limp Mode” activation, an unprompted Check Engine Light, or the vehicle failing to accelerate past a certain pedal threshold. Because this sensor is located right above the floor cabin mat, it is continuously subjected to dirt, winter salt boots dampness, and pedal vibrations which wear out the inner electrical tracks. When replacing the aftermarket unit, clean the mounting bracket area thoroughly. Ensure the pin harness clicks into place with a dry, airtight seal, and verify full pedal clearance before taking the truck back onto major freight routes.
