Inspection

1.	Turn the ignition switch OFF.

2.	Disconnect the ambient temperature sensor.

Check the resistance of the ambient temperature sensor between terminal “+” and “-” whether it is changed by changing of the ambient temperature.

Specification

Ambient temperature [°C(°F)]	Resistance [kΩ]	Voltage [V]
-30(-22)	480.41	4.71
-20(-4)	271.21	4.50
-10(14)	158.18	4.20

40(104)	16.13	1.75
50(122)	10.95	1.34

4.	If the measured resistance is not within specification, substitute with a known-good ambient temperature sensor and check for proper operation.

5.	If the problem is corrected, replace the ambient temperature sensor.

Replacement

1.	Disconnect the negative (-) battery terminal.

2.	Remove the front bumper cover. (Refer to Body - "Front Bumper Cover")
