This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the temperature sensor in the charging system is reading too high. It's like when a thermometer shows a higher temperature than it really is.
The P1C5B code indicates that the voltage signal from the cooling system temperature sensor in the universal charger extension control module is higher than expected.
The Universal Charger Extension Control Module monitors the cooling system temperature sensor to ensure proper operation. If the sensor's output voltage is higher than the predetermined threshold, the control module triggers the P1C5B code.
• Check engine light is on
• Charging system may not function properly
• Possible overheating of the charging system
• Faulty cooling system temperature sensor
• Wiring issues such as short to voltage
• Faulty universal charger extension control module
OBD-II: On-Board Diagnostics II, a standardized system for vehicle diagnostics
Multimeter: A tool used to measure electrical voltage, current, and resistance
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors of the temperature sensor.
• Test the temperature sensor for proper operation.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Replace the universal charger extension control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Vehicle 1
• Vehicle 2
• Vehicle 3
• Regularly inspect and maintain the charging system.
• Ensure proper connections and wiring integrity.
• Monitor for any signs of overheating.
Sensor Issue
• Have the vehicle inspected by a professional if the check engine light is on.
• Do not ignore the warning signs as it may lead to further damage.
Check with the vehicle manufacturer for warranty coverage on the control module and related components.
This code is relatively uncommon and typically associated with newer vehicle models equipped with advanced charging systems.
Moderate – It should be addressed soon to prevent potential damage to the charging system.
Driving with a faulty temperature sensor can lead to overheating and potential safety hazards.
• Vehicle must be in a safe and stationary position.
• Ensure the charging system is not actively charging.
The temperature sensor is located within the universal charger extension control module, typically near the vehicle's charging port.
Q: Can I drive with the P1C5B code?
A: It's not recommended to drive with this code active, as it may lead to overheating and further damage.
Q: How can I reset the check engine light?
A: After repairs, use an OBD-II scanner to clear the code and reset the check engine light.
