This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer found a problem with the sensor that checks the voltage when charging the car. It's like when your phone charger isn't working right, and your phone doesn't charge properly.
The P1C48 code indicates an issue with the voltage sensor circuit in the Universal Charger Extension Control Module, specifically that the voltage is lower than expected.
The Universal Charger Extension Control Module monitors the charge enable voltage sensor circuit to ensure proper charging operation. When the voltage reading is lower than the expected range, the system triggers the P1C48 code. This could be due to a fault in the sensor, wiring, or the control module itself.
• Charging system warning light on
• Vehicle may not charge properly
• Reduced charging efficiency
• Faulty voltage sensor
• Damaged or corroded wiring/connectors
• Malfunctioning Universal Charger Extension Control Module
Voltage Sensor: A device that measures the amount of electrical voltage in a circuit.
Universal Charger Extension Control Module: A component that manages the charging process in electric and hybrid vehicles.
• Check for any visible damage to the wiring and connectors.
• Use a multimeter to measure the voltage at the sensor.
• Test 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.

Moderate
• Chevrolet Volt
• Nissan Leaf
• Toyota Prius Plug-in
• Regularly inspect charging system components.
• Ensure connectors are clean and secure.
• Avoid exposure to extreme temperatures.
Sensor Issue
• Don't ignore the warning light; get it checked soon.
• Avoid using the vehicle's charging system until fixed.
Check with your vehicle manufacturer for warranty coverage on charging system components.
This code has become more common with the increased use of electric and hybrid vehicles, where charging systems are critical.
Moderate – It should be addressed soon to ensure the vehicle charges properly.
Failure to address charging system issues can lead to reduced vehicle performance and may affect warranty coverage.
• Vehicle in charging mode
• Ambient temperature within operational range
The Universal Charger Extension Control Module is typically located near the vehicle's charging port or battery compartment.
Q: Can I still drive my car with this code?
A: Yes, but it's best to get it fixed soon to ensure proper charging.
Q: Will this code affect my battery life?
A: If not addressed, it could lead to improper charging and potentially affect battery life.
