This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the sensor that checks how much power the air conditioner's motor is using. It's like when a toy's battery checker doesn't work right.
The A/C compressor motor current sensor monitors the electrical current used by the A/C compressor motor to ensure it is operating within the expected range.
The P0EAE code indicates that the current sensor for the A/C compressor motor is detecting a range or performance issue. This sensor is responsible for monitoring the electrical current flowing through the A/C compressor motor. If the sensor detects a current that is outside the expected range, or if its performance is compromised, the ECM (Engine Control Module) will trigger this code.
• A/C system not working properly
• Check Engine Light illuminated
• Unusual noises from the A/C system
• Reduced cooling performance
• Faulty A/C compressor motor current sensor
• Wiring issues or poor connections in the sensor circuit
• Malfunctioning A/C compressor motor
• Faulty ECM
A/C: Air Conditioning
ECM: Engine Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the A/C compressor motor current sensor.
• Test the A/C compressor motor current sensor with a multimeter.
• Check the A/C compressor motor for proper operation.
• Repair or replace faulty wiring or connectors.
• Replace the A/C compressor motor current sensor if faulty.
• Replace the A/C compressor motor if necessary.
• Reprogram or replace the ECM if needed.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance of the A/C system
• Periodic checks of electrical connections
• Routine inspection of the A/C compressor
Sensor Issue
• Have the A/C system inspected by a professional.
• Avoid using the A/C until the issue is resolved to prevent further damage.
Check with the vehicle manufacturer for warranty coverage on the A/C system components.
This code has been observed in hybrid and electric vehicles where the A/C compressor is electrically driven.
Moderate – While the vehicle can still be driven, the A/C system may not function properly, affecting comfort.
Driving without a functional A/C system is not a safety issue but may affect comfort in extreme temperatures.
• Engine running
• A/C system activated
The A/C compressor motor current sensor is typically located near the A/C compressor, often mounted on or near the compressor housing.
Q: Can I drive my car with this code?
A: Yes, but the A/C may not work properly, which can be uncomfortable in hot weather.
Q: Will this code affect my car's performance?
A: No, this code specifically affects the A/C system and not the overall vehicle performance.
