10) Check for each pressure of low side and high side if it is within shaded range of graph. If each gauge reading is out
of specified pressure, correct defective part referring to the following table.
When diagnosing troubles of abnormal pressure on the low side and high side for each pressure more specifically,
refer to “Trouble Diagnosis for Abnormal Pressure”.
NOTE
Pressure registered on gauge varies with ambient temperature. Therefore, use the graphs when
determining if pressures are normal or not.

Low side and high side pressure example, Gauges should read as follows when ambient temperature is 30
°C (86 °F)
Pressure on high pressure gauge (HI): 1130 – 1560 kPa (11.4 – 15.6 kgf/cm2)
Pressure on low pressure gauge (LO): 270 – 390 kPa (2.7 – 3.9 kgf/cm2)
High pressure gauge
[A]: Pressure of high pressure gauge [C]: Ambient temperature [E]: Acceptable range
[B]: Pressure of low pressure gauge [D]: Humidity
Condition Possible cause Correction
Pressure is higher than
acceptable range
(“A” area)Refrigerant overcharged Recharge.
Expansion valve frozen or clogged Check expansion valve.
Clogged refrigerant passage of high pressure side Clean or replace.
Condenser cooling fan malfunction (Insufficient
cooling of condenser)Check condenser cooling fan.
Dirty or bent condenser fins (Insufficient cooling of
condenser)Clean or repair.
Compressor malfunction (Insufficient oil etc.) Check compressor.
Engine overheat Check engine cooling system
referring to “Engine Cooling Symptom

1) Disconnect A/C refrigerant pressure sensor
connector.
2) Turn ignition switch to ON position.
3) Check if voltage between “RED” wire terminal and
“ORN” wire terminal of A/C refrigerant pressure
sensor connector is 4.75 V to 5.25 V.
If not, check A/C refrigerant pressure sensor circuit.
4) Connect A/C refrigerant pressure sensor connector

recovery and recycling equipment referring to
“Recovery” in “Operation Procedure for Refrigerant
Charge”.
2) Disconnect negative (–) cable from battery.
3) Disconnect A/C refrigerant pressure sensor
connector.
4) Remove A/C refrigerant pressure sensor (1) from
liquid pipe (2).Installation
Reverse removal procedure noting the following
instructions.
• Apply compressor oil to O-ring of A/C refrigerant
pressure sensor.
• Tighten A/C refrigerant pressure sensor to specified
torque.
Tightening torque
A/C refrigerant pressure sensor (a): 11 N·m (1.1
kgf-m, 8.0 lb-ft)
• Evacuate and charge the A/C system referring to
“Evacuation” and “Charge” in “Operation Procedure
for Refrigerant Charge”.
A/C Switch InspectionS6RW0D7216016
• Check that there is continuity between terminal (1)
and terminal (2) when A/C switch is at ON position.
• Check that there is no continuity between terminal (1)
and terminal (2) when A/C switch is at OFF position.
