9.
Remove throttle position sensor from engine speed control assembly (WP 0039 00).
a.
Turn engine start switch to OFF position (TM 5-3805-290-10).
b.
Record position of sensor before removing throttle position sensor.
c.
Remove throttle position sensor from housing (WP 0039 00) and inspect cables for signs of wear.
d.
Connect multimeter to terminal C of breakout T.
e.
Turn engine start switch to ON position (TM 5-3805-290-10).
f.
Record output signal of throttle position sensor with sensor slot in released position.

h.
Expected Results. Throttle position sensor output is 10 percent or less in released position. Throttle position sensor
output is 90 percent or more in advanced position.
(1)
If results are OK, operation of throttle position sensor is correct. Fault is caused by foot pedal or lever
assembly. Adjust or replace throttle pedal assembly (WP 0039 00). Verify repair eliminates problem.
(2)
If results are NOT OK, throttle position sensor is faulty. Replace throttle position sensor (WP 0039 00).
Verify repair eliminates problem.
