DTC P0532-00: Refrigerant Pressure Sensor Circuit Low Input: Notes
DETECTION CONDITION AND POSSIBLE CAUSE
| DTC P0532:00 |
Refrigerant pressure sensor circuit low input |
| DETECTION CONDITION |
- The PCM monitors input voltage from the refrigerant pressure sensor when the ignition switch is ON. 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)/Snapshot data is not available.
- The DTC is stored in the PCM memory.
|
| FAIL-SAFE FUNCTION |
- |
| POSSIBLE CAUSE |
- Refrigerant pressure sensor connector or terminals malfunction
- Short to ground in wiring harness between the following terminals:
- Refrigerant pressure sensor terminal A-PCM terminal 2BB
- Refrigerant pressure sensor terminal B-PCM terminal 2AX
- PCM connector or terminals malfunction
- Refrigerant pressure sensor signal circuit and ground circuit are shorted to each other
- Open circuit in wiring harness between refrigerant pressure sensor terminal A and PCM terminal 2BB
- Refrigerant pressure sensor malfunction
- PCM malfunction
