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 0.05V lasts for more than 1.25 sec., ECM sets P0552. MIL (Malfunction Indicating Lamp) turns on when the malfunction lasts till consecutive 2 driving cycles.
