Ignition "OFF"
Disconnect ambient temperature sensor.
Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature.
Ambient Temperature [°C (℉)] | Resistance between terminals 1 and 2 (㏀ ) |
-10 | 158.2± 3% |
0 (32) | 95.1± 3% |
10 (50) | 58.8± 3% |
20 (68) | 37.3± 3% |
If the measured resistance is not specification, substitute with a known-good ambient temperature sensor and check for proper operation.
If the problem is corrected, replace the ambient temperature sensor.
