Throttle Position Sensor: Testing and Inspection
Circuit Test
THROTTLE POSITION SENSOR (TPS)
The TPS is a variable resistor type that rotates with the throttle shaft to sense the throttle valve angle. As the throttle shaft rotates, the output voltage of
the TPS changes. The PCM detects the throttle valve opening based on this voltage change.
