Standard Motor Products TH399 Throttle Position Sensor tps

The Standard Motor Products TH399 is a direct-fit replacement throttle position sensor (TPS) engineered to restore precise throttle feedback to your vehicle's engine management system. Designed to match original equipment specifications, this sensor ensures accurate communication between the throttle body and the ECU for optimal drivability and efficiency.

The throttle position sensor monitors the angle and movement of the throttle valve, converting that position into an output voltage signal sent to the vehicle's computer. The ECU uses this data to regulate idle control, fuel enrichment, and fuel cut-off — all critical functions for smooth engine performance.

Key Features:

• OE-matched output — maintains specific installed voltages to match original equipment rather than using adjustable consolidated designs
• Circuits printed on flexible polyimide film or ceramic-based substrates for excellent dimensional stability and prevention of electrical performance drift
• Noble palladium/gold/platinum alloy contacts deliver low contact resistance and extended service life
• Integral rotor bearings and return springs included for straightforward installation
• Rigorous end-of-line testing with thousands of data points to validate output voltages for trouble-free operation
• Sold individually
• UPC: 707390632704

Standard Motor Products maintains complete quality control through the entire manufacturing process — from raw componentry to finished product — making the TH399 a reliable, professional-grade replacement for a worn or malfunctioning throttle position sensor.
