This summary uses the existing diagnostic information shown in full below.
The car's air conditioner has a sensor that checks how much power is going to the motor. This error means that one part of the sensor is getting a much higher reading than the others, which could mean something is wrong.
The error code indicates that the current sensor for the A/C compressor motor is detecting a higher current in phase U compared to phases V and W, suggesting an imbalance.
The A/C compressor motor uses a three-phase current sensor to monitor the electrical current in each phase (U, V, and W). The P1D2E code is triggered when the current in phase U is detected to be significantly higher than in phases V and W, indicating a potential fault in the sensor or electrical system.
• Reduced or no cooling from the A/C system
• Illuminated check engine light
• Unusual noises from the A/C compressor
• Faulty A/C compressor motor current sensor
• Wiring issues or poor connections
• Malfunctioning A/C compressor motor
A/C: Air Conditioning
Compressor: A device that compresses and circulates refrigerant in the A/C system
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the A/C compressor motor.
• Test the A/C compressor motor current sensor for proper operation.
• Replace the faulty A/C compressor motor current sensor.
• Repair or replace damaged wiring or connectors.
• Replace the A/C compressor motor if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Honda Accord
• Honda Civic
• Acura MDX
• Regularly inspect and maintain the A/C system.
• Ensure all electrical connections are secure.
• Use the A/C system regularly to prevent seizing.
Sensor Issue
• Have the A/C system checked by a professional.
• Avoid using the A/C system until repaired to prevent further damage.
Check with the vehicle manufacturer for warranty coverage on A/C components.
This code has been associated with vehicles experiencing A/C system failures due to sensor or electrical issues.
Moderate – While not critical, it should be addressed to restore A/C functionality and prevent potential damage.
Operating a vehicle with a malfunctioning A/C system may not pose immediate safety risks, but it can affect comfort and visibility in certain conditions.
• Vehicle at operating temperature
• A/C system turned on
The A/C compressor motor and its sensors are typically located at the front of the engine bay, near the radiator.
Q: Can I still drive my car with this code?
A: Yes, but the A/C might not work properly, and it should be fixed to avoid further issues.
Q: How can I prevent this issue?
A: Regular maintenance and inspections of the A/C system can help prevent sensor and electrical issues.
