The Walker Products Throttle Position Sensor (part number 200-91045) is a direct-fit replacement for 1986-1991 Chevrolet, GMC, Isuzu, and Pontiac vehicles with 7.4L, 5.0L, and 5.7L engines. Throttle Position Sensors measure throttle position through changing voltage and send this information to the onboard computer. The computer uses this and other inputs to calculate the correct amount of fuel delivered.
Features:
- Reduced Emissions: TPS assists in maintaining the correct air-to-fuel mixture, which in turn helps reduce harmful emissions, enhance fuel efficiency, reduce gas consumption.
- Resilience and Durability: Throttle Position Sensors are built to withstand challenging conditions and resist electromagnetic interference, ensuring their longevity and reliability in a variety of operating environments.
- Optimized Transmission Shifts: TPS data can aid in optimizing automatic transmission shifts, leading to smoother gear changes and improved driving comfort.
- Enhanced Engine Performance: TPS contributes to optimal ignition timing and fuel injection, resulting in improved engine performance, increased power output, and smoother operation.
- Diagnostic Capability: TPS are crucial for diagnosing engine issues based on the voltage signal interpreted by the ECU. If the sensor malfunctions, it can trigger error codes, making it easier to identify and make real-time adjustments.
