Throttle Position Sensor: Description and Operation
The TPS, connected to the throttle shaft, is a variable resistor with one end connected to 5 volts from the ECM and the other to ground. A third wire,
connected to the ECM, measures TPS voltage. TPS voltage changes with movement of the throttle valve. The ECM modifies fuel delivery according to
throttle valve angle, by monitoring TPS voltage.
