Transmission Fluid Temperature Sensor Check

Disconnect the A/T control solenoid valve assembly connector.

Measure the resistance between the sensor-side connector terminal No. 2 of the A/T control solenoid valve assembly connector and the ground.

FLUID TEMPERATURE AND RESISTANCE SPECIFICATION

Fluid temperature °C (°F)	Resistance kΩ
10 (50)	Approx. 6.62
25 (77)	Approx. 3.51
80 (176)	Approx. 0.55
110 (230)	Approx. 0.25

NOTE: In the information screen on the multi-information display, the fluid temperature warning comes on when the transmission fluid temperature is approximately 140°C (284 °F) or higher, and automatically goes out when the A/T fluid temperature dropped below approximately 135°C (275°F).

CAUTION: The A/T fluid temperature sensor cannot be removed or replaced as a single unit. When the A/T fluid temperature sensor needs to be replaced, replace the valve body assembly.

When the resistance of the transmission fluid temperature sensor is outside the standard value, and the fluid temperature warning comes on/goes out at other than the specified temperatures, replace the valve body assembly and the harness.
