4. Install jumper wire between pin B
and pin C on air inlet manifold
pressure sensor connector/turbo-
charger outlet pressure sensor
Figure 36).
5. Turn battery disconnect switch
and ignition switch to ON position
(TM 5-2410-241-10).
6. Check for Diagnostic Codes or
1. If active 273-4 code is present,
replace air inlet manifold pressure
sensor (WP 0092). Ensure all har-
ness connectors are reconnected.
Verify correct operation of
machine (TM 5-2410-241-10).
2. If active 273-3 code is present,
proceed to step 7.
7. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-2410-241-10).
8. Remove jumper wire from Air inlet
manifold pressure sensor connec-
tor/turbocharger outlet pressure
sensor connector N-C5
pin B and pin C.
9. Disconnect engine ECM connec-
(WP 0296), test for continuity
