Throttle Position Sensor: Description and Operation

Throttle position sensor (1991-)





The earlier throttle position switch has been superseded by a throttle position sensor which provides the control module with continuous and stepless information on the angle of the throttle butterfly. This information is used for various purposes, including fuel shut-off.

The throttle function is adaptive, i.e. the control module "learns" which signal corresponds to idling and which signal corresponds to full throttle. This means that manual adjustment is unnecessary.
