Monitoring, power supply 3, sensor CY320

Fault description
Monitoring, power supply 3, sensor CY320

Condition for fault identification
Test condition:
The sensor voltage supply is monitored by comparators in
the hardware. If the voltage supply is outside the switching
thresholds an error is reported. The recognition thresholds
are defined by the hardware and cannot be configured.
Terminal condition: Terminal 15
Voltage condition:
none

Condition for fault memory entry
0.5 sec.

Action in service
1. Connect adapter between wiring harness and DME to
allow measurement at Pin CME-122 (DME - intake
camshaft sensor)
2. Measure voltage on Pin CME-122,
if > 5 V -> short circuit to plus -> Check wiring harness
if < 5 V -> unplug the following sensors (see causes) in
sequence and measure when the voltage at Pin CME-122
goes to 5 V then replace the affected sensor, otherwise:
- Check wiring harness
- Replace DME
if = 5 V and logged continuously, replace the DME
