Checking the Hall sensor (electronic ignition systems) (VW Golf 2)

Prerequisites for testing: The TSZ-H system switching unit has been tested; ignition coil checked, wire between TSZ-H system switching unit and ignition distributors checked; the connectors of the ignition distributor, Hall sensor and TSZ-H system switching unit have been checked.

Remove the high-voltage wire from terminal 4 from the ignition distributor (middle wire) and connect it to the "ground" via an auxiliary wire. The cross-section of the auxiliary wire should be the same as that of the high-voltage wire.

Remove the rubber boot from the TSZ-H system switching unit connector. The connector remains connected.

Please note: The specified values apply to an ambient temperature of 0 to 40°C.

Connect the voltmeter to contacts 6 and 3 of the connected TSZ-H switching unit connector.

Turn on the ignition.

Turn the engine manually in the direction of operating rotation (clockwise). In this case, the voltmeter readings should change from 0 to at least 2 V, depending on whether the hood is in the air gap of the Hall sensor or not.

If there are any deviations from the specified values, replace the Hall sensor.
