This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the sensor that measures the voltage in a part of the air conditioning system. It's like a thermometer that isn't working right.
The vehicle's computer has detected a high voltage reading from the A/C Coolant Heater Phase W Voltage Sensor 'B', indicating a potential issue with the sensor or its circuit.
The P1D61 code is triggered when the Powertrain Control Module (PCM) detects a voltage level that is higher than expected from the A/C Coolant Heater Phase W Voltage Sensor 'B'. This could be due to a malfunctioning sensor, wiring issues, or a fault within the PCM itself.
• Check Engine Light is on
• Air conditioning system may not function properly
• Unusual noises from A/C system
• Faulty A/C Coolant Heater Phase W Voltage Sensor
• Wiring issues such as short circuits or open circuits
• Faulty PCM (Powertrain Control Module)
PCM: Powertrain Control Module, the computer that controls the engine and transmission.
A/C: Air Conditioning, a system in the vehicle that cools the air inside the cabin.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the A/C Coolant Heater Phase W Voltage Sensor for proper operation.
• Replace the faulty A/C Coolant Heater Phase W Voltage Sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Honda Accord
• Honda Civic
• Honda CR-V
• Regular maintenance of the A/C system
• Periodic checks of wiring and connectors
• Ensure sensors are functioning properly
Sensor Issue
• Have the vehicle inspected by a professional if the Check Engine Light comes on.
• Avoid using the A/C system until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on emissions-related components.
This code is relatively uncommon and typically occurs in vehicles with complex A/C systems.
Moderate – The vehicle can still be driven, but the A/C system may not work properly.
Driving with a malfunctioning A/C system may not be illegal, but it can affect comfort and safety, especially in extreme weather conditions.
• Vehicle engine running
• A/C system activated
The A/C Coolant Heater Phase W Voltage Sensor is typically located near the A/C compressor or coolant heater assembly.
Q: Can I drive my car with a P1D61 code?
A: Yes, but the A/C system might not work properly, which can be uncomfortable in hot weather.
Q: Is a P1D61 code serious?
A: It's not critical, but it should be addressed to ensure the A/C system functions correctly.
