21-115

4-door DTC 2: A Short in the In-car Temperature Sensor Circuit

1. Remove the in-car temperature sensor (see page 21-149).
2. Test the in-car temperature sensor (see page 21-150).

Is the resistance within the specifications shown on the graph?

YES - Go to step 3.

NO - Replace the in-car temperature sensor.

3. Disconnect climate control unit connector B (22P).
4. Check for continuity between the No. 9 terminal of climate control unit connector B (22P) and body ground.

CLIMATE CONTROL UNIT CONNECTOR B (22P)

Wire side of female terminals

Is there continuity?

YES - Repair short to body ground in the wire between the climate control unit and the in-car temperature sensor.

NO - Substitute a known-good climate control unit and recheck. If the symptom/indication goes away, replace the original climate control unit.

4-door

DTC 3: An Open in the Outside Air Temperature Sensor Circuit

1. Remove the outside air temperature sensor (see page 21-150).
2. Measure the resistance between the No. 1 and No. 2 terminals of the outside air temperature sensor.
   *Dip the sensor in ice water and measure resistance. Then pour hot water on the sensor and check for change in resistance.

OUTSIDE AIR TEMPERATURE SENSOR

*Is the resistance within the specifications shown on the graph?

YES - Go to step 3.

NO - Replace the outside air temperature sensor.

3. Disconnect climate control unit connector B (22P).
