Circuit Operation
- A 5-volt power supply is applied on the throttle position sensor power terminal (terminal No. 3) from the ECM (terminal No. 81 - M/T) or PCM (terminal No. 46 - A/T). The ground terminal (terminal No. 2) is grounded with ECM (terminal No. 92 - M/T) or PCM (terminal No. 57 - A/T).
- When the throttle valve shaft is turned from the idle position to the fully opened position, the resistor between the throttle position sensor output terminal (terminal No. 3) and ground terminal will increase according to the rotation.
