Engine Control - P0553 Power Steering Pressure Sensor/Switch Circuit High Input - General Information

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 PCM as a wheel position signal. Controlling idle speed valve, PCM performs appropriate electric load correction With this signal.

DTC Description

Checking output signals from P/S PS (power steering pressure sensor) every 2.5 sec. under detecting condition, if an signal above 4.95 V lasts for more than 1.25 sec., PCM sets P0553. MIL (Malfunction Indicating Lamp) turns on when the malfunction lasts till consecutive 2 driving cycles.
