P2517 GMC Code - Air Condition Refrigerant Pressure Sensor 'B' Circuit Low
Quick Answer
The Powertrain Control Module (PCM) monitors the refrigerant pressure through the Air Condition (A/C) Pressure Sensor. Common causes include Low refrigerant, Too much refrigerant, Faulty Low Side Pressure Sensor. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.
