P0552 DODGE – Power Steering Pressure Sensor Circuit Low Input

P0552 DODGE Possible Symptoms

Engine Light ON (or Service Engine Soon Warning Light),Power steering inoperative

P0552 DODGE Possible Causes

P0552 DODGE Description

Power steering pressure (PSP) sensor is installed to the power steering high-pressure tube and detects a power steering load. This sensor is a potentiometer which transforms the power steering load into output voltage, and emits the voltage signal to the Engine Control Module (ECM). 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.
