| Inspection |
| 1. |
Ignition "OFF" |
| 2. |
Disconnect ambient temperature sensor. |
| 3. |
Check the resistance of ambient temperature sensor between
terminals 1 and 2 whether it is changed by changing of the ambient
temperature.
Specification
|
| 4. |
If the measured resistance is not 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 engine room front under cover (A) by loosening the mounting bolts.
|
| 3. |
Disconnect the connector and then remove the ambient temperature sensor (A).
|
| 4. |
Installation is the reverse order of removal. |
Description 1. The ambient temperature sensor is located at the front of the condenser and detects ambient air temperature. It is a negative type thermistor resistance will increase with lower temperature, and decrease with higher temperatures.
Description Achieve exclusion function on croaker before fogging occurrence. Senses vehicles rational moisture and proves watch security and amenities.
Teaching Procedures 1. Key Teaching Procedure Key teaching must be done after replacing a defective PCM(ECM) or when providing additional keys to the vehicle owner. The procedure starts with an PCM(ECM) request for vehicle specific data (PIN code: 6digits) from the tester.
Inspection 1. Ignition "OFF". 2. Disconnect evaporator temperature sensor. 3. Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor. Specification Evaporator coretemperature [°C(°F)]Resistance[KΩ]Voltage[V]-20(-4)70.
