What does code P1532 mean?

Q: What does code P1532 mean?

A/C Evaporator Temperature Sensor Circuit Low Voltage. P1532 on a Chrysler vehicle means the powertrain control module (PCM) has detected an abnormally low voltage signal from the air conditioning (A/C) evaporator temperature sensor circuit. The PCM expects a voltage within a specific range that corresponds to the evaporator fin temperature, and a low voltage indicates a short to ground, a failed sensor, or a wiring fault.
