P1689-00 Fault Diagnosis and Resolution for Dodge 24 Valve Cummins Engine

Model: dodge 24 valve cummins Fault Code: P1689 Posted: 2008-05-23 10:57

I recently encountered a stored P1689-00 diagnostic code on my Dodge 24-valve Cummins engine, which caused the vehicle to fail to start. After replacing the injection pump, the truck started and runs smoothly. However, the P1680-00 code persists even after the repair. I'm seeking insights into what this specific fault code indicates and how to properly resolve it in a Chrysler-based Cummins diesel engine system.
