This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks there's too much electricity going through a part that helps the air conditioner work.
The P0EAA code is triggered when the powertrain control module (PCM) detects a high voltage condition in the A/C compressor motor voltage sensor B circuit.
The A/C compressor motor voltage sensor monitors the voltage levels of the A/C compressor motor. If the PCM detects a voltage level that is higher than the expected range, it triggers the P0EAA code, indicating a potential issue with the sensor or the circuit.
• A/C not functioning properly
• Check engine light on
• Unusual noises from the A/C system
• Faulty A/C compressor motor voltage sensor
• Wiring issues such as shorts or open circuits
• Faulty PCM
PCM: Powertrain Control Module
A/C: Air Conditioning
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the A/C compressor motor voltage sensor for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty A/C compressor motor voltage sensor.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect the A/C system wiring.
• Perform routine maintenance on the A/C system.
• Ensure the electrical system is in good condition.
Sensor Issue
• Avoid using the A/C until the issue is resolved.
• Have the vehicle inspected by a professional mechanic.
Check with the vehicle manufacturer for warranty coverage on the A/C system components.
This code has been reported in hybrid and electric vehicles where the A/C compressor is electrically driven.
Moderate – The A/C system may not work properly, which can be uncomfortable but not immediately dangerous.
Driving with a malfunctioning A/C system is not illegal, but it can affect comfort and potentially lead to other issues if not addressed.
• Vehicle at operating temperature
• A/C system turned on
The A/C compressor motor voltage sensor is typically located near the A/C compressor in the engine bay.
Q: Can I drive with a P0EAA code?
A: Yes, but the A/C system may not function properly, and it's best to get it checked soon.
Q: Will the P0EAA code affect my car's performance?
A: It mainly affects the A/C system and not the overall performance of the vehicle.
