The automatic transmission fluid temperature is between 20-150掳C (68-302掳F) for 10 s or more.

Diagnostic Aids

A correct transmission fluid level is required for a proper function. The automatic transmission fluid temperature sensor is located inside the

transmission at the valve body. To ensure that the shown oil temperature is correct, measure the oil temperature with an external thermometer.

Circuit/System Verification

1. Perform the Transmission Fluid Level and Condition Check (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Testing

and Inspection/Symptom Related Diagnostic Procedures/AF40-6 - Automatic Transmission/Transmission Fluid Level and Condition Check)

to verify correct fluid level.

2. Engine idling at operating temperature, observe the scan tool Transmission Fluid Temperature parameter. The reading should be between -40

to +215掳C (-40 to +488掳F) and change.

3. Operate the vehicle at about 60 km/h (37 MPH) for 10 min. Verify the scan tool Transmission Fluid Temperature parameter varies by more

than 2掳C (3.5掳F) to verify that the sensor is not stuck.

Circuit/System Testing

Operate the vehicle within the conditions for running and setting the DTC to verify the DTC does not reset. You may also operate the vehicle

within the conditions that you observed from the Freeze Frame/Failure Records data.

Component Testing

Static Test

1. Ignition OFF, remove the K71 Transmission Control Module.

2. Ignition OFF, test for infinite resistance between the low reference circuit terminal 7 X2 and ground.

瀚慖f less than the specified range, replace the wiring harness.

3. Ignition OFF, test for infinite resistance between the signal circuit terminal 8 X2 and ground.

瀚慖f less than the specified range, replace the wiring harness.

4. Test for infinite resistance between each terminal and the low reference circuit terminal 7 X2 and also to the signal circuit terminal 8 X2.
