MONITOR DESCRIPTION
The automatic transmission fluid (ATF) temperature sensor converts ATF temperature to an electrical resis-
tance value. Based on the resistance, the ECM determines the ATF temperature, and the ECM detects an
opens or shorts in the ATF temperature circuit. If the resistance value of the ATF temperature is less than
79 W or more than 156 kW, the ECM interprets this as a fault in the ATF sensor or wiring. The ECM will turn
on the MIL and store the DTC.

INSPECTION PROCEDURE
1 Check transmission wire.
PREPARATION:
Disconnect the transmission wire connector from the transmis-
sion.
CHECK:
Measure the resistance between terminals OT2+ and OT2-.
OK:
79 W to 156 kW
CHECK:
Measure resistance between terminals OT2+ and OT2- of the
transmission wire connector and body ground.
OK:
Resistance: 1 MW or higher
NG Replace the transmission wire (ATF tempera-
ture sensor).
OK
