Fault text

Valvetronic, eccentric shaft sensor: reference

Fault description

VVT-Reference Sensor Parity Error (Bank 1)

Condition for fault identification

Test condition:

VVT reference sensor monitor

No faults related to the sensor's voltage supply should be present (fault code 10800)

Terminal condition: Terminal 15 ON Voltage condition:

Electrical system voltage terminal 87 >10.0 V

Condition for fault memory entry

100 ms

Action in service

If faults (#10801) and (#10802) are simultaneously stored in the fault memory, proceed to check the following:

Dual fault is stored when VVT sensor is not connected to the DME. Is VVT sensor connected to the wiring harness? If not: Plug in and check wiring harness between DME and

VVT sensor.

Replace VVT sensor.

If only fault code (#10802) is entered:

1. Check signal wire (VVT sensor PIN 7, PIN 9) between VVT sensor and DME for breakage or short circuits and corroded plugs. 2. Determine whether a cycle signal is visible every 1 ms at sensor Pin 7. (Ignition on!). If yes, proceed to Item 3. If no, this signal wire is defective.

Determine whether a digital message is being transmitted through DME PIN 7-09 every 1 ms. If yes, proceed to Item

If no, this signal wire is defective.

4. Replace VVT sensor.
