P0554

2017-10-10

Description:

  • The fault code P0554 indicates that intermittent signal is detected in the power steering pressure sensor circuit. This may result in poor braking performance and difficulty in stopping the vehicle.

Possible Symptoms:

  • Engine misfires or runs rough, especially at idle or under load

  • Decreased engine performance or power

  • Poor fuel efficiency

  • Check Engine Light (CEL) illuminated

Possible Causes:

  • Faulty power steering pressure sensor

  • Open or short circuit in the power steering pressure sensor circuit

  • Poor electrical connection in the power steering pressure sensor circuit

  • Faulty power steering control module

  • Faulty engine control module (ECM)

Related Parts:

  • Power Steering Pressure Sensor: This sensor monitors the hydraulic fluid pressure in the steering system. Problems in this sensor lead to hard steering

Possible Solutions:

  • Test and replace the faulty ignition coil in cylinder 10, if necessary

  • Replace the spark plug in cylinder 10 if it is worn, fouled, or damaged

  • Clean or replace the fuel injector in cylinder 10 if it is clogged or malfunctioning

  • Perform a compression test to check for low compression in cylinder 10 and repair as needed

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