Linear Throttle Position Sensor VTA

The linear throttle position sensor is mounted to the throttle body. It is composed of two movable contacts, a fixed resistor, and four electrical terminals. The two movable contacts move along the same axis as the throttle valve. One is used for the throttle opening angle signal (VTA) and the other for the closed throttle signal (IDL).

The Linear Throttle Position Sensor has an electrical connector with four terminals.
