INSPECTION

PROCEDURE

1. INSPECT TRANSMISSION WIRE (ATF TEMPERATURE SENSOR)

(a) Measure the resistance according to the value(s) in the table below.

HINT:

If the resistance is out of the specified range at any of the ATF temperatures shown in the table below, the driveability of the vehicle may decrease.

Standard Resistance:

Tester Connection	ATF Temperature	Specified Condition
2 (OT-) - 13 (OT+)	10°C (50°F)	5 to 8 kΩ
2 (OT-) - 13 (OT+)	25°C (77°F)	2.5 to 4.5 kΩ
2 (OT-) - 13 (OT+)	110°C (230°F)	0.22 to 0.28 kΩ
3 (OT2-) - 14 (OT2+)	10°C (50°F)	5 to 8 kΩ
3 (OT2-) - 14 (OT2+)	25°C (77°F)	2.5 to 4.5 kΩ
3 (OT2-) - 14 (OT2+)	110°C (230°F)	0.22 to 0.28 kΩ

If the result is not as specified, replace the transmission wire.
