TEST OR INSPECTION
1. Check sensor.
(a) Turn battery disconnect and engine
start switches to ON position (TM 5-
(b) Disconnect wiring harness connector
from transmission oil temperature
sensor (WP 0092 00).
(c) At sensor connector, measure
1. If resistance is NOT between 18 Ohms
resistance between signal contact 1
and 34k Ohms, replace transmission oil
(wire R818-YL) and return contact 2
temperature sensor (WP 0092 00).
2. If resistance is between 18 Ohms and
34k Ohms, go to Test 2.
2. Check harness return circuit.
(a) Sensor remains disconnected.
(b) Turn battery disconnect and engine
start switches to OFF position (TM 5-
(c) Disconnect J1 and J2 wiring harness
connectors from powertrain ECM (WP
between contact 2 (wire J764-BR) of
wiring harness for sensor and contact
2. If resistance is greater than 5 Ohms,
J1-45 of wiring harness for ECM.
there is an open circuit between ground
contact and frame ground. Replace
wiring harness in question (WP 0195 00
thru WP 0201 00).
3. Check for a shorted harness.
(a) Sensor and ECM remain disconnected
from wiring harness.
(b) Battery disconnect and engine start
switches remain in OFF position (TM
