A/C pressure transducer visual inspection

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Disconnect A/C pressure transducer connector.

(3)

Check if corrosion and contamination at A/C pressure transducer terminal is detected.

(4)

Check A/C pressure transducer connecting torque and A/C refrigerant leakage.

(5)

Does any problem is detected at A/C pressure transducer?

YES

a.

Replace A/C pressure transducer and go to "Verification of Vehicle Repair".

NO

a.

Go to "2. Check A/C pressure transducer waveform " as follows.

2.

Check A/C pressure transducer waveform

(1)

IG KEY "OFF", ENGINE "OFF".

(2)

Connect A/C pressure transducer connector.

(3)

Connect oscilloscope to A/C pressure transducer connector terminal 2.

(4)

Monitor A/C pressure transducer waveform at idle as turning A/C "ON".

1)

Specification :

note

Output signal(voltage) changes in accordance with the amount of refrigerant and the change of weather.occurs

Check if normal pressure change in accordance with A/C compressor operation at normal pressure range shown in "Specification".

(5)

Is A/C pressure transducer waveform outputted correctly?

YES

a.

Go to "Verification of Vehicle Repair".

NO

a.

Replace A/C pressure transducer and go to "Verification of Vehicle Rapair".
