P0551 Power Steering Pressure Sensor/Switch Circuit Range/Performance - General Information

Component Location





General Description

To reduce the required power to manipulate steering wheel, hydraulic pressure is used in power steering system. A load is sensed at steering oil pressure sensor then inputted to ECM as a wheel position signal. Controlling idle speed valve, ECM performs appropriate electric load correction With this signal.

DTC Description

ECM sets DTC P0551 if the ECM detects signal exceeds the possible range of a properly operating sensor
