P0552 Power Steering Pressure Sensor/Switch Circuit Low input - 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

Checking output signals from P/S PS (power steering pressure sensor) every 2.5 sec. under detecting condition, if an signal below 0.05 V lasts for more than 1.25 sec., ECM sets P0552. MIL (Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2 driving cycles.
