This summary uses the existing diagnostic information shown in full below.
This code means the car's computer has detected that the sensor measuring the temperature of the air conditioning refrigerant is reporting a value that is too high.
The P0EBD code is triggered when the A/C refrigerant temperature sensor, which monitors the temperature of the refrigerant, sends a signal to the engine control module (ECM) that is higher than the expected range.
The A/C refrigerant temperature sensor is responsible for providing the ECM with the temperature of the refrigerant in the air conditioning system. A 'Circuit High' condition indicates that the sensor is sending a voltage signal that is higher than the normal operating range, which could be due to a sensor malfunction or an issue with the wiring or connectors.
• A/C system not functioning properly
• Check Engine Light illuminated
• Inconsistent cabin temperature
• Faulty A/C refrigerant temperature sensor
• Wiring issues such as shorts or open circuits
• Poor electrical connections at the sensor
ECM: Engine Control Module
A/C: Air Conditioning
• Use an OBD-II scanner to confirm the code.
• Visually inspect the A/C refrigerant temperature sensor and its wiring.
• Test the sensor's voltage and resistance with a multimeter.
• Replace the A/C refrigerant temperature sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive the vehicle to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Toyota Prius
• Chevrolet Volt
• Ford Fusion Hybrid
• Regularly inspect and maintain A/C system components.
• Ensure proper electrical connections.
• Perform routine diagnostic checks.
Sensor Issue
• Avoid using the A/C system until the issue is resolved.
• Consult a professional mechanic if unsure about repairs.
Check your vehicle's warranty coverage for sensor-related issues.
The P0EBD code has been associated with hybrid and electric vehicles due to their complex A/C systems.
Moderate – Addressing this issue will ensure proper A/C function and prevent further electrical issues.
Driving with a malfunctioning A/C system may not be safe in extreme temperatures. Address the issue promptly.
• Engine running
• A/C system activated
The A/C refrigerant temperature sensor is typically located near the A/C compressor or along the refrigerant line.
Q: Can I drive with the P0EBD code?
A: While you can drive with this code, it's best to fix it soon to ensure your A/C system works correctly.
Q: Will fixing this code improve my car's performance?
A: Fixing this code will primarily improve your A/C system's performance and reliability.
