Installation

Installation

WARNING

Install the component to the specified torques.
Note that internal damage may occur when the component is dropped. In this case, use it after inspecting.

Install in the reverse order of removal.

Accelerator Position Sensor (APS)

Description Accelerator Position Sensor (APS) is installed on the accelerator pedal module and detects the rotation angle of the accelerator pedal. The APS is one of the most important sensors in engine control system, so it consists of the tw

Oil Temperature Sensor (OTS)

Description It generates the oil pressure and temperature information (output voltage) to control the pump operation proportional control valve in variable oil pump system. It measures the oil pressure and temperature discharged from the oil p

Rail Pressure Sensor (RPS)

Description Installed on the delivery pipe, the Rail Pressure Sensor (RPS) measures the instantaneous fuel pressure in the delivery pipe. The sensing element (Semiconductor element) built in the sensor converts the pressure to voltage signal.
