Throttle Position Sensor: Description and Operation
TPS Location
The Throttle Position Sensor (TPS) is a rotating type variable resistor (that turns together with the throttle body throttle shaft) to sense the throttle valve
angle.
Throttle Position Sensor
As the throttle shaft rotates, the output voltage of the TPS changes. The ECU determines the throttle valve opening based on the output voltage. The
ECU computes throttle valve opening change (output voltage change) and judges the engine acceleration rate and accordingly corrects the fuel injection
amount during acceleration.
