Q: What does code P1541 mean?

A/C High Side Over Temperature. P1541 on Chrysler vehicles means the powertrain control module (PCM) has detected that the air conditioning (A/C) high-side refrigerant pressure has exceeded a safe temperature threshold, usually derived from the high-side pressure sensor. The PCM sets this code when the calculated or measured high-side temperature stays above the calibrated limit for a set time, often to protect the compressor and hoses from overpressure damage.
