Ford P0553 OBD-II Trouble Code Definition:
P0553 Power Steering Pressure Sensor Circuit High Input
P0553 Ford OBD-II Trouble CodeDescription:
OBD Trouble Code P0553
Power Steering Pressure Sensor/Switch Circuit High Input
What does the code mean? OBD-ii Code P0553 definition:
Power steering pressure (PSP) sensor is installed to the power steering high-pressure tube and detects a power steering load. This sensor is a potentiometer which transforms the power steering load into output voltage, and emits the voltage signal to the PCM. The PCM controls the electric throttle control actuator and adjusts the throttle valve opening angle to increase the engine speed and adjusts the idle speed for the increased load.

Symptoms Sumptoms of OBD code P0553
– Engine Light ON (or Service Engine Soon Warning Light) – Power steering inoperative
– Engine Light ON (or Service Engine Soon Warning Light) – Power steering inoperative
Causes Causes of the OBD-II code P0553
– Power steering pressure sensor harness or connectors – Power steering pressure sensor harness is open or shorted – Power steering pressure sensor The Error code is generally activated on detection of the following conditions: A low voltage from the sensor is sent to PCM.
