Q: What does code P1547 mean?

A/C System Performance Degraded. P1547 on Chrysler vehicles means the powertrain control module (PCM) has detected that the air conditioning (A/C) system is not cooling as efficiently as it should. The PCM monitors the A/C refrigerant pressure and/or evaporator temperature and compares the actual performance to expected values, setting this code when performance degrades beyond a calibrated threshold.
