Electric Hydraulic Power Steering
C2420 Motor temperature sensor high input - General Information

Component Location





General Description

EHPS (Electro Hydraulic Power Steering) is assitance steering ability system uses electrical motor that generate oil pressure not to use the Engine power.
Temperature sensor is installed is MPU(Motor Pump Unit) in order to measure oil temperature, This sensor uses a thermistor whose resistance changes according to the temperature changes.
MPU ECU perform limit current control to prevent from over-heating and motor speed control according to viscosity changes.

DTC Description

This DTC code is set when supplied over current or input too high temperature to MPU ECU, in order to protect MPU ECU. The MPU not perform EHPScontrol.
