What is P0558 fault code and what does it mean? What is Brake Boost Pressure Sensor Circuit Low Input malfunction? How do you fix the P0558 fault code What are the causes of P0558 fault code symptoms?
What is the P0558 Fault code? What does it signify?
P0558 is one possible fault code related to the brake booster pump circuit. This code means that the brake booster pressure sensor circuit is not operating properly due to a malfunction detected by the powertrain control module (PCM). Other fault codes that can be related to the brake booster sensor include P0556 (P0556), P0557, and P0559.
The brake booster pressure sensor circuit measures the amount of pressure applied to hydraulic brake booster. The PCM controls this circuit, which can adjust to different braking situations, adjust brake pedal pressure, and assist in pedal operation. This is required to stop or slow down the vehicle when the driver applies minimal force to the brake pedal.
The brake booster pressure is too high, a P0558 code means. If the PCM does not receive a voltage signal proportional the decrease in vehicle speed that is caused by the driver pressing the brake pedal, or the maximum parameters set forth by the manufacturer, the code P0558 will be set.
The P0558 fault code can affect vehicles of all makes and models, including but not limited to: Subaru, Suzuki, Dodge. Chrysler, Ford. Opel. Hyundai. Chevrolet. Volkswagen.
What causes the P0558 Fault code?
These are the most common reasons that P0558 is triggered
- Defective brake booster pressure sensor
- – Leaky or damaged vacuum lines or tubing
- – Corroded, damaged or loose connectors
- – Short-circuited, damaged or faulty cables
- – Defective vacuum hose non-return valve
- – Defective brake booster
- – Defective PCM
What are the symptoms of P0558 malfunction code?
You may experience the following symptoms if your vehicle has the code P0558:
- – The engine light will flash when the brake pedal is pressed.
- The brake warning light can flash or stay on if the brake pedal has been pressed.
- To stop the vehicle from accelerating or stopping, it may be necessary to push the brake pedal harder
- – Hardening your brake pedal
How do I fix the P0558 fault code?
The following repairs may be able to resolve the P0558 fault code:
- Repairing the brake booster pressure sensor that is defective
- – Cleaning corrosion and replacing damaged connectors
- – Repair of short-circuited, damaged wiring
- Replacement of leaking vacuum lines or hoses
- – How to replace a defective brake booster
- – Check the PCM for damage and replace it if necessary
How Serious Is the P0558 Fault Code
The severity of the code is dependent on the fault. It will get worse if it is not fixed quickly. The vehicle’s safety may be endangered if the fault is not addressed immediately. In some cases, this code can cause the brake pedal to become harder.
