4. Permatex Super 300 to threads
5. Locking nut
6. In--- built amplifier
Connector A:
1. Earth wire
2. Signal wire
3. Supply wire
Direct current (DC) is fed into the ACD position sensor (ear-
lier alternating current).

The position sensor connector is fitted at the end of the
sensor.
Note! The positon sensor cannot be repaired but a defect
sensor must be changed for a new one.
Important! Fault code number 22 indicates, that the posi-
tion sensor does not function. Diagnostic light and fault
codes, see the following instr. C.
Measuring position sensor supply and signal
voltages
Sensor voltages can be measured as earlier by using spe-
cial tool ETV 894 100 and a universal instrument, see page
320/13.
