Hella 008476781 Throttle Position Sensor Slider Type, 3-Pin

The Hella 008476781 is a throttle position sensor (TPS) designed to monitor throttle angle and relay precise positional data to the engine control unit in real time. By continuously tracking where the throttle plate sits throughout the acceleration range, it enables the ECU to fine-tune fuel delivery and ignition timing for responsive, efficient engine operation. This sensor uses a slider-type sensing element housed in a plastic body with a round, 3-pin female connector and is designed for throttle cable or intake manifold mounting rather than direct throttle body mounting.

Key Features:

• Slider-type sensor design for precise, continuous throttle angle monitoring
• Provides real-time positional feedback to the ECU for optimized fuel delivery and ignition timing
• Supports smooth idle control and accurate diagnostic readings
• Plastic housing with durable, wear-resistant electronic components for long-term reliability
• Round, 3-pin female connector with male pin terminals; 2-bore mounting with bracket included
• 12V operating voltage; anticlockwise rotation direction
• Mounting bracket included; mounting hardware not included

Engineered to Hella's professional-grade standards, this throttle position sensor is a dependable replacement for restoring proper throttle response and drivetrain efficiency. Fits select 1987–1995 Chevrolet, Pontiac, Oldsmobile, Buick, GMC, and Cadillac models. Installation by qualified personnel is recommended.
