A throttle switch sensor, often referred to as a throttle position sensor (TPS), monitors the throttle valve opening and its rate of change. It sends signals to the ECU, which adjusts fuel injection, idle speed, and transmission shift logic accordingly. Critical for electronic throttle control and cruise control systems, a faulty TPS can cause engine hesitation or poor idle. Our TPS units for Japanese, American, German, French, and Chinese vehicles ensure precise driver input translation. Contact us for specifications and compatibility.
