DTC Description
P0532 A/C PRESSURE SENSOR CIRCUIT LOW
VOLTAGE
Is DTC P0532 indicated?
YES : Check for poor connections or loose terminals at the A/C pressure sensor and the PCM. If the PCM was
updated, substitute a known-good PCM See PCM UPDATE or PCM REMOVAL AND
INSTALLATION , then recheck. If the PCM was substituted, go to step 1.
NO : Troubleshooting is complete. If the PCM was substituted, replace the original PCM See PCM
REMOVAL AND INSTALLATION or PCM UPDATE . If any other Pending or Confirmed DTCs are
indicated, go to the indicated DTC's troubleshooting.

1. Start the engine, and let it idle.
2. Turn the blower switch on.
3. Turn the A/C switch on.
4. Check the parameter(s) below with the HDS.
Threshold
Signal
Current conditions
Unit Values Unit
Values
A/C PRESSURE SENSOR More than 4.75 V
Do the current condition(s) match the threshold?
YES : The failure is duplicated. Go to step 2.
NO : Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at
the A/C pressure sensor and the PCM.
2. Determine possible failure area (A/C pressure sensor, others):
ο‘
1. Turn the ignition switch to LOCK (0).
2. Disconnect the following connector.
ο‘
A/C pressure sensor 3P connector
ο‘
3. Connect terminals A and B with a jumper wire.
Terminal A A/C pressure sensor 3P connector No. 1 (GRY)
Terminal B A/C pressure sensor 3P connector No. 2 (BLU)

Is there continuity?
YES : The PD SENSOR wire is OK. Update the PCM See PCM REMOVAL AND INSTALLATION
or PCM UPDATE if it does not have the latest software, or substitute a known-good PCM See PCM
REMOVAL AND INSTALLATION or PCM UPDATE , then do the repair verification .
NO : Repair an open in the PD SENSOR wire between the PCM (A27) and the A/C pressure sensor, then
do the repair verification .
