For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article .
Theory of operation
The Electronic Throttle Control (ETC) system uses two Throttle Position Sensors (TPS) to monitor the accelerator pedal position. The TPS sensors 1 and 2 are located within the throttle body assembly. Each sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. Processors are also used to monitor the ETC system data. The processors are located within the Powertrain Control Module (PCM). Each signal circuit provides processors with a signal voltage proportional to throttle blade movement. The processors share and monitor data to verify that the indicated TPS calculation is correct.
