Advanced Diagnostics - DTC P0532: A/C Pressure Sensor Circuit Low Voltage
General Description
The A/C pressure sensor measures the change in the pressure of the air conditioning refrigerant. The signal from the A/C pressure sensor is low voltage at low pressure (when the air conditioning load is low) and high voltage at high pressure (when the air conditioning load is high). The powertrain control module (PCM) compares the expected voltage to the A/C pressure sensor output voltage. When the A/C pressure sensor output voltage is lower than the expected voltage for a set time, the PCM detects a malfunction and stores a DTC.
Monitor Execution, Sequence, Duration, DTC Type, OBD Status
Enable Conditions
Malfunction Threshold
The A/C pressure sensor output voltage is 0.24 V or less for at least 10 seconds.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, a Confirmed DTC and the freeze data are stored. The MIL does not comes on.
Conditions for clearing the DTC
The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
