The P1531 fault code refers to a problem with the AC Low Side Temperature Sensor. This sensor is monitored by the HVAC Control Module, which is responsible for regulating the heating, ventilation, and air conditioning system in your vehicle. The sensor measures the temperature of the evaporator, and when the air is cold, the sensor resistance and signal voltage are high.

Conversely, when the air is warm, the sensor resistance and signal are low. If you are experiencing this fault code, it means that there is an issue with the AC Low Side Temperature Sensor. This could result in improper temperature regulation in your vehicle’s HVAC system, leading to discomfort or inefficient cooling.

It is important to have this issue addressed by a qualified technician to ensure optimal performance of your AC system.
