Throttle Full Close Switch: Testing and Inspection

Each switch opens or closes the circuit depending on throttle position. The switch functions are checked by making continuity checks with an ohmmeter at the switch connector. Image above shows Volkswagen special tool no. VW 1501 (order no. TV1 501 000 24 ZEL) attached to the throttle switch connector in place of the normal wiring harness connector on a ClS-E engine. The test harness provides convenient test points, but the switches can be tested without it.
