CORRECTIVE ACTION
5. Disconnect connector E-C2
262-4 Five-Volt Sensor
(WP 0012, Figure 31) from fuel rail
Power Supply Voltage Is
pressure sensor.
Below Normal or the Voltage
6. Turn battery disconnect switch and
Is Shorted Low - Continued
ignition switch ON (TM 5-3805-
298-10).
NOTE
During the following tests diagnostic codes 0100-03, 1785-03, and
1797-03 should become active. These codes are due to open circuits on
the pressure sensors and should be ignored.
7. Using MSD, check for active
Diagnostic Code 262-4 Five-Volt
diagnostic codes (WP 0008).
Sensor Power Supply Voltage Is
Below Normal Remains Active -
Proceed to Test Step 3.
Diagnostic Code 262-4 Five-Volt
Sensor Power Supply Voltage Is
Below Normal Becomes Inactive -
Proceed to step 8.
8. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-298-10).
9. Connect connector E-C10
(WP 0012, Figure 15) to engine oil
pressure sensor.
10. Turn battery disconnect switch and
ignition switch ON (TM 5-3805-
298-10).
11. At MSD, check for active
Diagnostic Code 262-4 Five-Volt
diagnostic codes (WP 0008).
Sensor Power Supply Voltage Is
Below Normal Becomes Active -
Replace engine oil pressure sensor
(WP 0246)
Proceed to Test Step 4.
Diagnostic Code 262-4 Five-Volt
Sensor Power Supply Voltage Is
Below Normal Remains Inactive -
Proceed to step 12.
12. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-298-10).
13. Connect E-C8 (WP 0012,
Figure 30) to intake manifold
pressure sensor.
