DTC P0533-00: Refrigerant Pressure Sensor Circuit High Input: Notes
DTC P0533:00 DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0533:00 |
Refrigerant pressure sensor circuit high input |
| DETECTION CONDITION |
- The PCM monitors input voltage from the refrigerant pressure sensor. If the input voltage at the PCM terminal 2W is above 4.9 V for 5 s, the PCM determines that the refrigerant pressure sensor circuit has a malfunction.
Diagnostic support note
- This is a continuous monitor (other).
- The check engine light does not illuminate.
- FREEZE FRAME DATA is not available.
- Snapshot data is available.
- DTC is stored in the PCM memory.

| FAIL-SAFE FUNCTION |
|
| POSSIBLE CAUSE |
- Refrigerant pressure sensor connector or terminals malfunction
- PCM connector or terminals malfunction
- Refrigerant pressure sensor malfunction
- Short to power supply in wiring harness between refrigerant pressure sensor terminal B and PCM terminal 2W
- Open circuit in wiring harness between the following terminals:
- Refrigerant pressure sensor terminal B-PCM terminal 2W
- Refrigerant pressure sensor terminal A-PCM terminal 2V
- PCM malfunction
