P0551 - Power Steering Pressure Sensor/Switch Circuit Performance






General Description
The power steering system increases steering performance and improves steering feel and power-saving effectiveness. The power steering pressure switch senses the power steering load and converts it into a voltage (high/low) signal to the ECM. The ECM then controls the idle speed control motor by using the voltage signal from the power steering pressure switch.

DTC Description
If a power steering pressure switch signal to the ECM is ON when the enable conditions are met, the ECM determines that a fault exists and a DTC is stored.
