Standard Motor Products TH75 Throttle Position Sensor OE Replacement TPS

The Standard Motor Products TH75 is a direct-fit OE replacement throttle position sensor (TPS) engineered to restore precise throttle monitoring and engine management performance. Designed to match original equipment specifications, this sensor delivers reliable, accurate readings that the engine control unit depends on for proper fuel delivery, idle control, and overall driveability.

How It Works:

The throttle position sensor monitors the angle and movement of the throttle plate, converting that position into a voltage signal transmitted to the vehicle's ECU. The computer uses this data to calculate optimum fuel enrichment, idle control, and fuel cut-off conditions — making a properly functioning TPS essential to engine efficiency and responsiveness.

Key Features:

• OE-Matched Output: Maintains specific installed output voltages to match original equipment — not an adjustable consolidated design
• Advanced Circuit Construction: Circuits printed on flexible polyimide film or ceramic-based substrates for excellent dimensional stability and prevention of electrical performance drift
• Noble Metal Alloy Contacts: Palladium/gold/platinum alloy contact surfaces provide low contact resistance and extended service life
• Integral Rotor Bearings & Return Springs: Built-in components simplify installation and ensure consistent mechanical operation
• Rigorous End-of-Line Testing: Each sensor is validated through thousands of data points to confirm accurate output voltages before leaving the factory
• Direct Plug-In Fitment: Engineered for a hassle-free, no-modification installation

A failing throttle position sensor can cause symptoms such as poor acceleration, rough or unstable idle, hesitation, and illumination of the check engine light — commonly associated with diagnostic trouble codes P0120 and P0121. The Standard Motor Products TH75 is a trusted solution for restoring proper engine operation to OE standards.
