Laymans terms

This code means that the car's charger system is detecting a voltage that's too high in a specific part of the charging system. It's like when a toy gets too much power from its batteries and might not work right.

Explanation

The code indicates an issue with the voltage sensor circuit within the power factor correction converter of the Universal Charger Extension Control Module, where the voltage is higher than expected.

Technical description

The P1C67 code is triggered when the Universal Charger Extension Control Module detects that the voltage sensor circuit in the Power Factor Correction Converter is reading a voltage level that is outside the normal range, specifically too high. This can affect the charging efficiency and safety of the vehicle's electrical system.

Symptoms

• Check engine light on

• Charging issues

• Reduced battery performance

Common Causes

• Faulty voltage sensor

• Wiring issues such as a short or open circuit

• Malfunctioning Universal Charger Extension Control Module

Glossary
