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
