1. Check sensor resistance.
(a) Turn engine start and battery
disconnect switches to OFF position
(TM 5-3805-291-10).
(b) Disconnect wiring harness from torque
converter output speed sensor (WP
0091 00).
(c) Measure resistance between contacts 1 1. If resistance is between 800 and 1,800
and 2 of speed sensor connector.
Ohms, go to Test 2.
2. If resistance is not between 800 and
1,800 Ohms, replace speed sensor.
Adjust speed sensor properly when
installing (WP 0091 00).
2. Check signal circuit for an open circuit
wiring harness.
(a) Engine start and battery disconnect
switches remain in OFF position (TM
5-3805-291-10).
(b) At wiring harness connector for speed
sensor, place a jumper between contact
1 and contact 2.
(c) Disconnect wiring harness connector
J1 from powertrain ECM (WP 0063
00).
(d) Measure resistance between contact
1. If there is less than 5.0 Ohms resistance,
J1-15 and contact J1-16.
go to Test 3.
2. If there is more than 5,000 Ohms
resistance, there is an open circuit in
wiring harness (wire E909-WH or wire
E908-BR). Replace wiring harness in
question (WP 0195 00 thru WP 0201
00).
