Test sequence: Notes

WARNING: This page is about a different car, the 2001 Audi A6, 2000 Audi A6, 1999 Audi A6, and 1998 Audi A6. However, it is still accessible from the selected car via links, so may be relevant.

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 .
