Crankshaft Syncropulse For Dieselpump Defective


Fault symptoms


• CHECK ENGINE lamp on.

• Limp home.


Note

Before starting fault diagnosis, see Erroneous generation of DTCs .


Conditions

The following conditions apply for this DTC:


• No synchronisation for more than 15 pump revolutions.


Diagnostic help

The control module uses the speed from the crankshaft position sensor divided by 2 as substitute value. If there is any other DTC in the PSG 16 control module, fault diagnosis begins with that. When the pump control module detects that there is no synchronisation pulse from the crankshaft position sensor, it could be due to a crankshaft position sensor fault.
