Code P105A MINI Description

The P105A MINI code indicates that there is an issue with the Internal Control Module VVT (Variable Valve Timing) where the error voltage is too high. The VVT system is responsible for adjusting the timing of the engine's valves to optimize performance, fuel efficiency, and emissions. When the voltage is too high, it can lead to incorrect valve timing, which can result in poor engine performance, reduced fuel efficiency, and increased emissions. If not addressed, this issue can potentially lead to engine misfires, reduced power, and even engine damage over time.
