Code P2517 Chrysler Description

The P2517 Chrysler code indicates a problem with the Air Condition Refrigerant Pressure Sensor 'B' Circuit being too low. The air conditioning system in vehicles relies on the proper pressure of refrigerant to function effectively. The refrigerant pressure sensor is responsible for monitoring the pressure levels in the system and sending this information to the engine control module (ECM). When the sensor detects that the pressure is too low, it triggers the P2517 code.

Tech Notes for P2517 Chrysler

Do not just add more refrigerant, use an A/C machine to evacuate the refrigerant and charge the correct amount.

When is the Code Detected?

The Powertrain Control Module (PCM) sets the code when detects a short to ground at the A/C low side pressure sensor signal circuit.
