This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the air conditioner's pressure sensor isn't working right because it is reading a very low pressure.
The P2517 code is triggered when the Powertrain Control Module (PCM) detects a low voltage signal from the A/C refrigerant pressure sensor B circuit.
The A/C refrigerant pressure sensor monitors the pressure of the refrigerant in the air conditioning system. A 'Circuit Low' condition indicates that the voltage from the sensor is below the expected range, which could be due to a faulty sensor, wiring issues, or low refrigerant levels.
• Air conditioning not working properly
• A/C compressor not engaging
• Check Engine Light illuminated
• Faulty A/C refrigerant pressure sensor
• Wiring issues such as shorts or open circuits
• Low refrigerant levels
PCM: Powertrain Control Module, the car's main computer
Refrigerant: The fluid used in the A/C system to provide cooling
• Use an OBD-II scanner to confirm the code
• Inspect the A/C refrigerant pressure sensor and wiring
• Check refrigerant levels in the A/C system
• Replace the A/C refrigerant pressure sensor
• Repair or replace damaged wiring
• Recharge the A/C system with refrigerant
• OBD-II scanner
• Multimeter
• A/C manifold gauge set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly check A/C system for leaks
• Ensure proper refrigerant levels
• Perform routine maintenance on the A/C system
Sensor Issue
• Do not ignore the Check Engine Light
• Have the A/C system inspected by a professional
• Avoid using the A/C system until the issue is resolved
Check with your vehicle manufacturer for warranty coverage on A/C components.
This code has been commonly reported in vehicles with aging A/C systems or after refrigerant leaks.
Moderate – While it may not affect drivability, it can lead to discomfort and further A/C system damage if ignored.
Ensure all repairs are conducted in accordance with local laws and safety regulations.
• Engine running
• A/C system activated
The A/C refrigerant pressure sensor is typically located on the high-pressure side of the A/C system, near the condenser or compressor.
Q: Can I drive my car with this code?
A: Yes, but the A/C may not function properly, and it could lead to further damage if not addressed.
Q: Will this code affect my car's performance?
A: No, it primarily affects the air conditioning system, not the engine's performance.
