| Description |
A/C pressure transducer measures the pressure in high pressure line and converts it into voltage. Based on the converted voltage, engine ECU controls cooling fan by operating it at high or low speed. Engine ECU stops the operation of compressor when the temperature of refrigerant line is too high or low irregularly to optimize air conditioning system.

| Inspection |
| 1. |
Measure the pressure of high pressure line by measuring voltage output between terminals “1” and “2”.
|
| 2. |
Check if the voltage is within specification.
|
| 3. |
If the measured voltage is not wihtin specification, replace the A/C pressure transducer.
|
| Replacement |
| 1. |
Disconnect the negative (-) battery terminal. |
| 2. |
Recover the refrigerant with a recovery/charging station. |
| 3. |
Disconnect the A/C pressure transducer connector (A). |
| 4. |
Remove the A/C pressure transducer (B).
|
| 5. |
Install in the reverse order of removal.
