P0552 Power Steering Pressure Sensor/Switch Circuit Low 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 below 0.05V lasts for more than 1.25 sec., PCM sets P0552. MIL(Malfunction Indicatin Lamp) turns on when the malfunction lasts till consecutive 2 driving cycles.
