Throttle Position Angle Sensor

This sensor is a mechanical variable resistor (potentiometer) connected to throttle shaft. Throttle position sensor varies voltage signal to ECU as throttle angle changes.

Other input signals which may be used on some or all models include signals from A/C clutch, brake switch, clutch switch, cranking signal (fused starter switch), vehicle speed sensor, power steering pressure switch and/or gear position switch(es).
