Q: What does code P0552 mean?

Power Steering Pressure Sensor/Switch Circuit Low Input. P0552 means the power steering pressure sensor or switch is reporting a voltage below the normal range to the engine computer, which interprets this as a low-pressure condition in the power steering system. The computer expects a signal that rises and falls with steering load, and a constant low reading tells it the circuit is grounded or the sensor has failed.
