Throttle Position Sensor: Description and Operation
Throttle Position Sensor
PURPOSE
The sensor is a variable resistor (potentiometer) that is used by the Engine Control Module (ECM) to detect throttle movement and position.
OPERATION
A 5 volt reference signal is applied from the ECM. When the throttle is opened the sensor resistance changes which is read as a varying voltage
signal. At idle position the sensor voltage is approx. 0.5 volt and approx. 4.5 volt at full throttle.
CONSTRUCTION
The sensor is a variable resistor (potentiometer) that is used by the ECM to detect throttle movement and position.
