This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer detected a problem with the sensor that checks the voltage when charging. It's like the sensor isn't getting enough power to work properly.
The P1C46 code indicates a problem with the voltage sensor circuit responsible for enabling the charging process in the Universal Charger Extension Control Module.
The Universal Charger Extension Control Module monitors the charge enable voltage sensor to ensure the charging system is functioning correctly. A 'Circuit Low' condition suggests that the voltage reading is below the expected threshold, which can prevent the charging system from operating as intended.
• Charging system malfunction
• Warning light on the dashboard
• Inability to charge the vehicle
• Faulty voltage sensor
• Wiring issues such as shorts or open circuits
• Defective Universal Charger Extension Control Module
Voltage Sensor: A device that measures the voltage in a circuit.
Circuit Low: A condition where the voltage is below the expected level.
• Check for any visible damage to the wiring or connectors.
• Use a multimeter to measure the voltage at the sensor.
• Inspect the Universal Charger Extension Control Module for faults.
• Replace the faulty voltage sensor.
• Repair or replace damaged wiring or connectors.
• Replace the Universal Charger Extension Control Module if necessary.
• Multimeter
• OBD-II scanner
• Screwdriver set

Moderate
• Vehicle 1
• Vehicle 2
• Vehicle 3
• Regular inspection of charging system components.
• Ensure all electrical connections are secure.
• Avoid exposing the charging system to extreme conditions.
Sensor Issue
• Do not attempt to charge the vehicle until the issue is resolved.
• Consult a professional mechanic if unsure about the repair process.
Check with the vehicle manufacturer for warranty coverage on electrical components.
This code has been reported in vehicles with advanced charging systems, often due to sensor wear or electrical issues.
Moderate – It should be addressed soon to avoid charging failures.
Driving with a malfunctioning charging system can lead to battery issues and potential vehicle shutdown.
• Vehicle in a safe, stationary position.
• Battery fully charged or connected to an external power source.
The Universal Charger Extension Control Module is typically located near the vehicle's battery or charging port.
Q: Can I drive my car with this code?
A: It's not recommended as the charging system may not function properly.
Q: How can I clear this code?
A: Fix the underlying issue and use an OBD-II scanner to clear the code.
