Test sequence: Notes

• Disconnect 3-pin connectors from hall sensors. The locations of the Camshaft Position (CMP) sensors are as follows:
  1. - Cylinder bank 1 Camshaft Position (CMP) Sensor -G40-Right front cylinder head
  2. - Cylinder bank 2 Camshaft Position (CMP) Sensor 2 -G163-Left rear cylinder head
  Fig 1: Disconnecting Pin Connectors From Hall Effect (CMP) Sensors

  
  NOTE:

  • Cylinder bank 1 = in driving direction, right
  • Cylinder bank 2 = in driving direction, left
  • Before disconnecting harness connectors, mark allocation to component.
• Connect multimeter between terminal 1 (B+) and 3 (Ground -GND-) for voltage measurement for the respective connector for hall sensor.

• Switch ignition on.

  Specified value: at least 9.0 V

• Switch ignition off.

If there is no voltage:

• Connect test box to control module wiring harness. See TEST BOX, CONNECTING FOR WIRING TEST .

• Check wires between test box and 3 -pin connector for open circuits according to wiring diagram.

Wire resistance: max: 1.5Ω
