COOLANT TEMPERATURE SENSOR ERROR

Step
1. Disconnect the coolant temperature sensor connector from the
FATC harness.
1 2. Measure the resistance between the coolant temperature sensor
connector terminals..
Does the measured resistance indicate 2.2 kΩ at 25 °C?
Replace the coolant temperature sensor.
2
Is the repair complete?
1. Remove the controller with connecting the connector.
2. Turn the ignition switch to ON.
3
3. Measure the voltage between terminal B9 and connector A13.
Does the measured voltage indicate 2.2 V at 25 °C?

4
Is the repair complete?
Replace the controller.
5
Is the repair complete?
Step
1. Disconnect the I/P wiring harness connector form the air mix door
motor.
1 2. Use an ohmmeter to measure the resistance between terminals 5
and 7 on the air mix door motor.
Is the resistance within the specified value?
Replace the air mix door motor.
2
Is the repair complete?
Use an ohmmeter to measure the resistance between terminals 2 and 3
on the air mix door motor.
3
Does the measured resistance indicate approximately 3 kΩ?
Replace the air mix door motor.
4
Is the repair complete?
Use an ohmmeter to measure the resistance between terminals 6 and
3, 6 and 2 on the air mix door motor.
5
Does the measured resistance indicate approximately 3 kΩ?
Replace the air mix door motor.
6
Is the repair complete?
Check the connector terminals at the air mix door motor and the wiring
in the FATC harness.
7
Is there a problem with any terminal on either the harness connector or
the motor connector or the wiring?
1. Remove the FATC controller from the instrument panel.
2. Disconnect the harness connectors of the controller.
3. Examine the connector terminals on the harness connectors and the
8
controller connectors and the harness wiring.
Is there a problem with any of these connectors or the wiring?
Repair the problem found with a connector terminal or wiring.
