DTC P0532; PCM REFRIGERANT PRESSURE SENSOR CIRCUIT LOW INPUt: Notes
WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
DETECTION CONDITION & POSSIBLE CAUSE
| DTC P0532:00 |
Refrigerant pressure sensor circuit low input |
| DETECTION CONDITION |
- The PCM monitors input voltage from the refrigerant pressure sensor. If the input voltage at the PCM terminal 2AX is below 0.1 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 (Mode 2) is not available.
