3.
Inspect Throttle Pedal Assembly.
a.
Inspect throttle pedal assembly for components that are loose, bent, missing, or worn (WP 0039 00).
b.
Slowly depress and release pedal.
c.
Throttle pedal assembly should operate smoothly without excessive drag. Pedal should spring back smoothly to
low idle position without assistance.
Expected Results. Throttle pedal assembly functions properly.
d.
(1)
If results are OK, proceed to step 4.
(2)
If results are not OK, throttle pedal assembly is in poor repair. Replace throttle pedal assembly (WP 0039
00).
4.
Check status for "Throttle Position".
a.
Connect ET to diagnostic connector (WP 0005 00).
b.
Turn engine start switch to ON position (TM 5-3805-291-10).
c.
Observe status for "Throttle Position" on ET while you operate throttle pedal through entire range of travel.
Expected Results. Status is zero percent when throttle pedal is released. Status progressively increases to 100 per-
d.
cent when throttle pedal is pressed.
(1)
If results are OK, throttle position sensor is working properly. There may be an intermittent electrical prob-
lem with harness or connectors. Refer to Electrical Connector Inspection (WP 0022 00) if problem is
intermittent.
(2)
If results are not OK, throttle position displayed on ET does not correspond to movement of throttle pedal.
Proceed to step 5.
