2017-10-10

Description:

  • The fault code P0558 indicates that the brake booster pressure sensor is sending a signal that is too high to the Engine Control Module (ECM), indicating a potential issue with the power steering system.

Possible Symptoms:

  • Hard brake pedal or increased brake pedal effort

  • Brake system malfunction

  • ABS (Anti

  • lock Braking System) or ESC (Electronic Stability Control) warning lights illuminated

  • Check Engine Light (CEL) illuminated

Possible Causes:

  • Faulty brake booster pressure sensor

  • Open or short circuit in the brake booster pressure sensor circuit

  • Poor electrical connection in the brake booster pressure sensor circuit

  • Faulty brake booster control module

  • Faulty engine control module (ECM)

Related Parts:

  • Brake Booster Pressure Sensor: Brake Booster Pressure Sensor measures the pressure in the brake line that provides extra braking power. Problems lead to inefficient braking and may cause accidents

Possible Solutions:

  • Test and replace the faulty brake booster pressure sensor, if necessary

  • Check for any open or short circuits in the brake booster pressure sensor circuit and repair as needed

  • Ensure proper electrical connections in the brake booster pressure sensor circuit

  • Test and replace the brake booster control module if it is determined to be faulty

  • Test and replace the engine control module (ECM) if it is determined to be faulty
