(WP 0018, Figure 35) from atmo-
spheric pressure sensor
(WP 0090).
8. Turn battery disconnect switch
and ignition switch to ON position
(TM 5-2410-241-10).
9. Check for Diagnostic Codes or
1. If active code 262-4 code is pres-
Event Codes (WP 0013).
ent, proceed to step 10.
2. If 262-4 code is not active,
replace atmospheric pressure
sensor (WP 0090). Ensure all har-
ness connectors are reconnected.
Verify correct operation of
machine (TM 5-2410-241-10).
10. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-2410-241-10).
11. Disconnect air inlet manifold pres-
sure sensor connector/turbo-
charger outlet pressure sensor
connector N-C5 (WP 0018,
Figure 36) from inlet manifold
pressure sensor (WP 0092).
12. Turn battery disconnect switch
and ignition switch to ON position
(TM 5-2410-241-10).
13. Check for Diagnostic Codes or
1. If active code 262-4 code is pres-
Event Codes (WP 0013).
ent, proceed to step 14.
2. If 262-4 code is not active,
replace inlet manifold pressure
sensor (WP 0092). Ensure all har-
ness connectors are reconnected.
Verify correct operation of
machine (TM 5-2410-241-10).
14. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-2410-241-10).
15. Disconnect turbocharger inlet
pressure sensor connector V-C20
(WP 0018, Figure 37) from turbo
inlet pressure sensor (WP 0066).
16. Turn battery disconnect switch
and ignition switch to ON position
(TM 5-2410-241-10).
