PCM monitors output signals from A/C pressure sensor. If a signal is above 4.65V for more than 10 seconds, the PCM sets a P0533 DTC.
Item | Detecting Condition | Possible cause |
DTC Strategy |
•
Detects sensor signal short to high voltage | 1. Poor connection 2. Short in signal circuit 3. Open in ground circuit 4. Faulty A/C Pressure sensor 5. Faulty PCM |
