Inspection
- Measure the high-pressure line pressure by measuring the output voltage between terminals No. 1 and No. 2.
- Check that the voltage value is within the specified range.
Voltage = 0.00878835 * Pressure + 0.5 [PSIA]
- If the measured voltage value does not meet the specification, replace the A/C pressure sensor.
Replacement
- Disconnect the negative (-) battery terminal.
- Recover the refrigerant using a recovery/recharging station.

- If PAG oil is mixed with the system's POE oil, dielectric breakdown may occur due to reduced volume resistance, and the compressor may not operate.
- Disconnect the air conditioner pressure sensor connector (A).
- Remove the air conditioning pressure sensor (B). [Without Heat Pump]
[With Heat Pump]
- Install in the reverse order of removal.
