Hall Effect Sensor

WARNING: This page is about a different car, the 1995 Volkswagen Passat. However, it is still accessible from the selected car via links, so may be relevant.
  1. Remove coil secondary wire and attach to ground. Disconnect Hall Effect sensor harness connector at distributor. Using an LED Test Light (US 1115), check for voltage between outer terminals of connector. See Fig 1 and Figure. With ignition on, light should be on. If light is on, go to next step. If light is not on, check wiring for short or open circuit. If wiring is okay, replace ignition control unit.
  2. Reconnect Hall Effect sensor harness connector. Pull back Hall Effect sensor boot to expose contact terminals. Connect LED Test Light (US 1115) probe to center contact and battery positive terminal. See Fig 1. Observe test light while cranking engine. If test light blinks, Hall Effect sensor is okay. If light does not blink, replace Hall Effect sensor.
