Laymans terms

This code means that the car's computer has detected a problem with a sensor that helps control the brakes. It's like the car is saying, 'I can't tell where the brake helper is.'

Explanation

The code C058D is triggered when the vehicle's control module detects a high voltage signal from the brake booster motor position sensor circuit.

Technical description

The brake booster motor position sensor monitors the position of the brake booster motor. When the sensor circuit sends a voltage signal that is higher than the expected range, the control module sets the C058D code, indicating a potential issue with the sensor or its circuit.

Symptoms
