Throttle Switch
NOTE:
Vanagon models use a contact type throttle switch with 2-wire connector.
A contact-type throttle switch 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 potentiometer within the air flow meter prevents loss of engine power during sudden acceleration/deceleration by signaling the ECU of necessary fuel enrichment requirements.
