P0551 Mitsubishi Description

Power steering pressure (PSP) sensor is installed to the power steering high-pressure tube and detects a power steering load.

The ECM controls the electric throttle control actuator and adjusts the throttle valve opening angle to increase the engine speed and adjusts the idle speed for the increased load.
