TROUBLESHOOTING PROCEDURE
CAUTION
All active fault codes must be investigated prior to replacing the engine Electronic Control Module
(ECM). Failure to comply may cause damage to equipment.
NOTE
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#723,
FMI#2), harness wiring is shared by the camshaft position sensor, the fuel rail pressure sensor,
the water-in-fuel sensor, and the intake manifold pressure/temperature sensor.

MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
1. Sensor supply errors.
1. Install fuse box (WP 0277, Vol
2).
2. Connect battery cables (WP
0357, Vol 2).
3. Start engine and run at idle for
1 minute (TM 5-3895-385-10).
