1. |
Measure the pressure of high pressure line by measuring voltage output between NO.1 and NO.2 terminals. |
2. |
Inspect the voltage value whether it is sufficient to be regular value or not.
Voltage = 0.00878835 * Pressure + 0.5 [PSIA]
|
|
3. |
If the measured voltage value is not specification, replace the A/C pressure transducer. |
1. |
Disconnect the negative (-) battery terminal. |
2. |
Recover the refrigerant with a recovery/charging station. |
3. |
Disconnect the A/C pressure transducer connector (A) and then remove the A/C pressure transducer (B).
Tightening Torque :
10~12N.m (1.0~1.2kgf.m, 7.4~8.8lbf.ft)
|
Take care that liquid & suction pipe are not bent. |
|
4. |
Installation is the reverse order of removal. |
Description
A/C pressure transducer convert the pressure value of high
pressure line into voltage value after measure it. By converted voltage
value, engine ECU controls cooling fan by operatin ...
Description
The evaporator temperature sensor will detect the evaporator
core temperature and interrupt compressor relay power in order to
prevent evaporator freezing by excessive cooling. ...
