This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks there's something wrong with the sensor that checks the voltage in a part of the car that changes electricity from one form to another.
The DC/DC converter in a hybrid or electric vehicle converts high voltage from the battery to a lower voltage for the car's electrical system. This code indicates a problem with the sensor that monitors the voltage within the converter.
The P1D14 code is triggered when the vehicle's control module detects an implausible voltage reading from the DC link voltage sensor within the DC/DC converter. This sensor is critical for ensuring the converter operates correctly and safely.
• Check engine light illuminated
• Vehicle may not start
• Reduced electrical performance
• Faulty DC link voltage sensor
• Wiring issues in the sensor circuit
• Malfunctioning DC/DC converter
DC/DC Converter: A device that converts direct current (DC) from one voltage level to another.
Voltage Sensor: A sensor that measures the electrical potential difference between two points.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections to the DC link voltage sensor.
• Test the sensor for proper operation.
• Replace the faulty DC link voltage sensor.
• Repair or replace damaged wiring or connectors.
• Replace the DC/DC converter if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Honda Accord Hybrid
• Toyota Prius
• Chevrolet Volt
• Regular maintenance checks
• Ensure proper electrical connections
• Avoid overloading the electrical system
Sensor Issue
• Do not ignore the check engine light.
• Have the vehicle inspected by a professional promptly.
Repairs may be covered under the vehicle's powertrain warranty if applicable.
This code has been reported in hybrid and electric vehicles due to the complexity of their electrical systems.
Moderate – Address the issue soon to avoid potential electrical failures.
Driving with a malfunctioning DC/DC converter can lead to electrical failures, which may be unsafe.
• Vehicle in 'On' position
• Battery fully charged
The DC/DC converter is typically located in the engine bay or under the vehicle, depending on the model.
Q: Can I drive my car with a P1D14 code?
A: It's best to have it checked as soon as possible to avoid potential electrical issues.
Q: What happens if I ignore this code?
A: Ignoring the code may lead to electrical system failures and reduced vehicle performance.
