This summary uses the existing diagnostic information shown in full below.
This code means that a sensor in your car that checks the temperature of a part called the DC/DC converter is showing a very low reading. It's like a thermometer saying it's super cold when it shouldn't be.
The DC/DC converter temperature sensor 'D' is reading a voltage that is lower than the expected range, indicating a potential issue with the sensor or its circuit.
The P1CED code is triggered when the Powertrain Control Module (PCM) detects a voltage signal from the DC/DC converter temperature sensor 'D' that is below the specified threshold. This could indicate a problem with the sensor itself, the wiring, or the connections involved in the circuit.
• Check Engine Light illuminated
• Possible reduction in fuel efficiency
• Potential issues with vehicle charging system
• Faulty DC/DC converter temperature sensor
• Wiring issues such as shorts or open circuits
• Poor electrical connections in the sensor circuit
DC/DC Converter: A device that converts direct current (DC) from one voltage level to another.
PCM: Powertrain Control Module, the computer that controls the engine and transmission.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connections for damage or corrosion.
• Test the DC/DC converter temperature sensor for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty DC/DC converter temperature sensor.
• Clear the code and test drive the vehicle to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Basic hand tools (screwdrivers, pliers)

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect electrical connections for corrosion.
• Ensure proper maintenance of the vehicle's electrical system.
• Avoid exposure of the vehicle to extreme temperatures.
Sensor Issue
• Do not ignore the Check Engine Light; have the vehicle inspected.
• Regular maintenance can prevent sensor issues.
• Consult a professional mechanic if unsure about repairs.
Check if your vehicle's warranty covers sensor issues or electrical components.
This code is more common in hybrid and electric vehicles due to their reliance on DC/DC converters.
Moderate – While not immediately critical, it should be addressed to prevent potential charging issues.
Driving with a malfunctioning sensor can lead to reduced vehicle performance and efficiency.
• Ensure the vehicle is at operating temperature.
• Perform tests in a controlled environment to avoid false readings.
The DC/DC converter temperature sensor is typically located near the vehicle's DC/DC converter, often in the engine compartment or under the hood.
Q: Can I drive with the P1CED code?
A: It's possible to drive, but it's recommended to fix the issue to avoid potential problems with the vehicle's charging system.
Q: How do I clear the P1CED code?
A: After fixing the issue, use an OBD-II scanner to clear the code. If the problem persists, the code may reappear.
