Dtc P0533: A/C Refrigerant Pressure Sensor "A" Circuit High - Suzuki Swift Sport 2004 Service & Repair Manual

1A-132 Engine General Information and Diagnosis:
Step
7 A/C refrigerant pressure sensor check
1) Check A/C refrigerant pressure sensor referring to "A/C
Refrigerant Pressure Sensor and Its Circuit Inspection in
Section 7B" or "A/C Refrigerant Pressure Sensor and Its
Circuit Inspection in Section 7B".
Is it in good condition?

DTC P0533: A/C Refrigerant Pressure Sensor "A" Circuit High

Wiring Diagram
Refer to "DTC P0532: A/C Refrigerant Pressure Sensor "A" Circuit Low".
DTC Detecting Condition and Trouble Area
DTC detecting condition
A/C refrigerant pressure sensor signal voltage is higher
than 4.93 V for 0.5 sec. continuously.
(1 driving detection logic but MIL does not light up)
DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch turned OFF.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Check DTC.
DTC Troubleshooting
NOTE
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors referring to "Inspection of ECM and Its Circuits".
• Upon completion of inspection and repair work, perform "DTC Confirmation Procedure" and
confirm that the trouble has been corrected.
Step
1 Was "Engine and Emission Control System Check"
performed?
2 A/C refrigerant pressure sensor power supply circuit
check
1) Disconnect connector from A/C refrigerant pressure
sensor with ignition switch turned OFF.
2) Check for proper connection of A/C refrigerant pressure
sensor at "GRY/RED", "RED" and "ORN" wire terminals.
3) Turn ON ignition switch, measure voltage between
engine ground and "GRY/RED" wire terminal of A/C
refrigerant pressure sensor connector.
Is voltage 4 – 6 V?
