Laymans terms

This code means that the car's computer thinks the brake pedal isn't moving as it should when you press it. It's like when you push a toy car and it doesn't roll as far as you expect.

Explanation

The brake pedal position sensor measures how far and how fast the brake pedal is pressed. This code indicates that the sensor is not detecting the expected change in position.

Technical description

The C106B code is triggered when the brake pedal position sensor detects a gradient (change in position) that is lower than expected. This could be due to a faulty sensor, wiring issues, or mechanical problems with the brake pedal assembly.

Symptoms

• Brake warning light on the dashboard

• Unusual brake pedal feel

• Reduced braking performance

Common Causes

• Faulty brake pedal position sensor

• Wiring issues or poor connections

• Mechanical problems with the brake pedal
