Throttle Position Sensor (TPS)

A contact-type TPS is installed on the throttle chamber of all models. It converts throttle position into electrical signals to inform ECU of throttle position. Signals are sent to ECU when throttle is fully open or at idle. See Fig 1 . The open contacts prevent loss of power during sudden acceleration/deceleration by signaling ECU of the required fuel enrichment.
