This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is having trouble getting a steady reading from a sensor that checks the voltage in part of the car's electrical system. It's like when a flashlight flickers because the batteries aren't making good contact.
This code indicates that the voltage sensor labeled 'B' in the DC/DC converter circuit is sending intermittent or erratic signals to the vehicle's control module.
The DC/DC converter is responsible for converting high voltage from the battery to a lower voltage for use by the vehicle's electrical systems. The voltage sensor B monitors this conversion process. If the sensor's signal is inconsistent or erratic, it may cause issues with the vehicle's power supply.
• Fluctuating electrical power
• Warning lights on the dashboard
• Possible reduced vehicle performance
• Faulty voltage sensor B
• Loose or corroded electrical connections
• Malfunctioning DC/DC converter
DC/DC Converter: A device that converts direct current (DC) from one voltage level to another.
Voltage Sensor: A component that measures the voltage in an electrical circuit.
• Check for any loose or corroded connections in the DC/DC converter circuit.
• Test the voltage sensor B for proper operation.
• Inspect the DC/DC converter for faults.
• Secure or replace any loose or corroded connections.
• Replace the faulty voltage sensor B.
• Repair or replace the DC/DC converter if necessary.
• Multimeter
• OBD-II scanner
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly check and clean electrical connections.
• Perform routine maintenance on the vehicle's electrical system.
• Monitor dashboard warning lights and address issues promptly.
Sensor Issue
• If you notice any warning lights, have the vehicle checked as soon as possible.
• Avoid using high electrical loads until the issue is resolved.
• Consider having a professional inspect the vehicle to prevent further damage.
Repairs may be covered under the vehicle's powertrain or emissions warranty. Check with the manufacturer or dealer.
This code is more common in hybrid and electric vehicles due to their complex electrical systems.
Moderate – While not immediately critical, it should be addressed soon to avoid potential power supply issues.
Driving with a malfunctioning electrical system can lead to reduced vehicle performance and safety risks.
• Vehicle at operating temperature
• Electrical system under load
The DC/DC converter and its sensors are typically located near the vehicle's battery or electrical control unit.
Q: Can I drive my car with this code?
A: It's possible to drive short distances, but it's best to have it checked to avoid potential issues.
Q: What happens if I ignore this code?
A: Ignoring it could lead to more significant electrical problems and reduced vehicle performance.
