Abstract
A method for diagnosing a performance issue in a vehicle system having a diesel engine, a fuel system, and an on-board diagnostic system. The method includes cranking the engine, and, if a pressure sensed in the fuel system during or after the engine cranking differs by a threshold amount from the pressure sensed during a previous operation of the engine, indicating excessive fuel viscosity in the on-board diagnostic system.
