This code means there's a problem with a sensor that helps control the brakes in your car. It's like if a toy car's remote control isn't working right, so the car doesn't stop when you want it to.
The C058E code indicates an issue with the position sensor circuit for the brake booster motor B. This sensor helps the car's computer know the position of the brake booster motor, which is crucial for proper brake function.
The brake booster motor B position sensor is responsible for providing feedback on the position of the brake booster motor to the vehicle's control module. If the sensor's signal is out of the expected range or performance is inconsistent, the control module will trigger the C058E code.
• Illuminated check engine light
• Reduced braking performance
• Unusual brake pedal feel
• Faulty brake booster motor B position sensor
• Damaged wiring or connectors in the sensor circuit
• Malfunctioning brake booster motor
Brake Booster: A component that helps increase the force applied to the brakes.
Position Sensor: A device that detects the position of a component and sends this information to the vehicle's control system.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the brake booster motor B position sensor for proper operation.
• Replace the faulty brake booster motor B position sensor.
• Repair or replace damaged wiring or connectors.
• Replace the brake booster motor if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Regularly inspect brake system components.
• Ensure all electrical connections are secure and clean.
• Perform routine maintenance as per the vehicle's service schedule.
Sensor Issue
• Have the brake system inspected by a professional.
• Avoid driving the vehicle until the issue is resolved if braking performance is severely affected.
Check with your vehicle manufacturer for warranty coverage on brake system components.
This code is relatively uncommon and often associated with vehicles that have advanced braking systems.
High – Brake issues can significantly affect vehicle safety.
Driving with a malfunctioning brake system can be dangerous and is not recommended.
• Vehicle parked on a level surface.
• Ignition in the 'on' position without starting the engine.
The brake booster motor B position sensor is typically located near the brake booster assembly in the engine compartment.
Q: Can I drive with the C058E code?
A: It's not recommended to drive with this code active, as it can affect your vehicle's braking performance.
Q: How do I reset the C058E code?
A: After repairs, you can use an OBD-II scanner to clear the code, but ensure the issue is fixed first.
