All active fault codes must be investigated prior to replacing the engine Electronic Control Module
(ECM). Failure to comply may cause damage to equipment.
Some sensors share harness wiring. Malfunctions in certain sensors, or in the engine ECM, may
cause false errors to display because of this shared wiring. For this malfunction (SPN#97,
FMI#3), harness wiring is shared by the water in fuel sensor, the camshaft position sensor, the
rail fuel pressure sensor, and the intake manifold pressure/temperature sensor.
