P0551 Power Steering Pressure Sensor Circuit Range/Performance
P0551 OBD Code Description:
OBD2 Code P0551 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 ECM or PCM. The ECM or 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 P0551
– Engine Light ON (or Service Engine Soon Warning Light) – Power steering inoperative
Possible Causes
Possible causes of P0551
– Power steering pressure sensor harness or connectors – Power steering pressure sensor harness is open or shorted – Faulty power steering pressure sensor – Faulty power steering pump The Error code is generally activated on detection of the following conditions: An out of range voltage from the sensor is sent to ECM or PCM.
