Throttle Angle Sensor: Description and Operation
Throttle Position Sensor
PURPOSE
The sensor is a variable resistor (potentiometer) that is used by the ECU to detect throttle movement and position.
LOCATION
The throttle angle sensor is mounted on and driven by the throttle body unit.
CONSTRUCTION
The sensor is a variable resistor (potentiometer) that is used by the ECU to detect throttle movement and position.
OPERATION
A 5 volt reference signal is applied from the ECU and a ground signal. 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. 0.5V and approx. 4.5 V at full throttle.
