Electric Hydraulic Power Steering
C1262 Temperature Sensor Failure - 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

The MPU set this code If the input value of temperature sensor is higher or lower than normal value.
