1.CHECK FLUID TEMPERATURE SENSOR (PART 1) Check resistance between transmission unit harness connector terminals.

Transmission unit harness connector | Condition | Resistance (Approx.)
Connector | Terminal
B50 | 45 | 46 | Transmission oil temperature: 20°C (68°F) | 6.36–6.68 kΩ
Transmission oil temperature: 50°C (122°F) | 2.17–2.23 kΩ
Transmission oil temperature: 80°C (176°F) | 0.86–0.89 kΩ

Is the inspection result normal?
YES>>GO TO 2.
NO>>Repair or replace damaged parts.
2.CHECK FLUID TEMPERATURE SENSOR (PART 2)
Check continuity between transmission unit harness connector terminal and ground.

Transmission unit harness connector | Ground | Continuity
Connector | Terminal
B50 | 45 | Ground | Not existed

Is the inspection result normal?
YES>>INSPECTION END
NO>>Repair or replace damaged parts.
