A/C Refrigerant Pressure Sensor B Circuit Low

Where it lives

For P2517, the sensor sits on the circuit this code reports. The description of P2517 reports a fault at the sensor.

Check these first

• Low refrigerant from a system leak
• A failed A/C refrigerant pressure sensor B
• A sensor B wire shorted to ground
• A sensor B that is not seated or calibrated

What to do next

1. Read A/C refrigerant pressure sensor B on a scan tool
2. Check for a refrigerant leak and the charge level
3. Test the sensor B wire for a short to ground
4. Verify the sensor B reference voltage
5. Replace the A/C refrigerant pressure sensor B if the charge and circuit test good
6. Clear the code and retest
