Throttle Position Sensor: Description and Operation
Throttle Position (TP) Sensor-1
The non-adjustable TP sensor is mounted on the throttle body assembly opposite the throttle lever. The TP sensor senses the throttle valve angle and
relays that information to the VCM. Knowledge of throttle angle is one of the inputs needed by the VCM to generate the required injector control signals
(pulses). For further information on replacement, refer to TP Sensor Replacement.
