1A-136 Engine General Information and Diagnosis:
DTC P0532: A/C Refrigerant Pressure Sensor Circuit Low
S4RS0A1104075
Wiring Diagram
8 Idle air control valve circuit check
1) Measure resistance between “BLK” wire terminal of idle
air control valve connector and vehicle body ground with
ignition switch turned OFF.
Is resistance continuity?
Go to Step 9. “BLK” wire is open
circuit.
9 Idle air control valve signal check
1) Connect connector to idle air control valve.
2) Using oscilloscope, check that idle air control valve duty
pulse is outputted referring to “Reference waveform
No.19” and “Reference waveform No.20” of “Inspection
of ECM and Its Circuits: ”.
Is duty pulse outputted at “C37-49” terminal of ECM
connector?
Replace idle air control
valve. Go to Step 10.
10 Idle air control valve circuit check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Using service wire, ground “E23-60” terminal of ECM
connector because of main relay turned ON.
3) Measure voltage between “C37-49” terminal of ECM
connector and vehicle body ground with ignition switch
turned ON.
Is voltage 10 – 14 V?
Substitute a known-
good ECM and recheck. Replace idle air control
valve.
