P0553 OBD Code Description:

OBD2 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

Possible sumptoms of P0553
– Engine Light ON (or Service Engine Soon Warning Light) – Power steering inoperative Possible Causes

Possible causes of 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. Possible Solutions
