C2421 HYUNDAI Description
The Electro Hydraulic Power Steering (EHPS) is assistance steering ability system uses an electrical motor that generates oil pressure not to use the Engine power. The Temperature Sensor is installed in the Motor Pump Unit (MPU) in order to measure oil temperature, This sensor uses a thermistor whose resistance changes according to the temperature changes. The MPU ECU perform limit current control to prevent from over-heating and motor speed control according to viscosity changes. The MPU set this code If the input value from the temperature sensor is too low and not control EHPS.
