Turn the ignition switch ON.
Remove the front bumper.
(Refer to Body - "Front Bumper")
Disconnect ambient temperature sensor.
Check the resistance of the ambient temperature sensor between terminals 1 and 2 whether it changes by changing the ambient temperature.
1. Ambient Sensor (+) | 2. Ambient Sensor (-) |
Ambient temperature [°C(°F)] | Resistance between terminals 1 and 2 (㏀) |
-10(14) | 164.2 |
0 (32) | 97.5 |
10 (50) | 59.6 |
20 (68) | 37.5 |
If the measured resistance is not within specification, substitute with a known-good ambient temperature sensor and check for proper operation.
Replace the ambient temperature sensor if it is proved that there is a problem with the sensor.
Disconnect the negative (-) battery terminal.
Remove the front bumper.
(Refer to Body - "Front Bumper")
Disconnect the connector (B) and then remove the ambient temperature sensor (A).
Install in the reverse order of removal.
