P0532

-
PINPOINT TEST 10: DTC P0532 OR P0533 - HYBRID

Normal Operation

Under normal operation, the A/C pressure transducer receives a ground from the PCM. A 5-volt reference voltage is supplied to the A/C pressure transducer from the PCM. The A/C pressure transducer then sends a voltage to the PCM to indicate the A/C pressure.

- DTC P0532 (A/C Pressure Refrigerant Sensor A Circuit Low) - The A/C pressure transducer inputs a voltage to the PCM. If the voltage is below the calibrated level, this DTC sets.
- DTC P0533 (A/C Pressure Refrigerant Sensor A Circuit High) - The A/C pressure transducer inputs a voltage to the PCM. If the voltage is above the calibrated level, this DTC sets.

Possible Causes
- Wiring, terminals or connectors
- A/C pressure transducer
- PCM
