Hyundai Tucson: Accelerator Position Sensor (APS)
Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / Engine Control - Fuel System / 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 two sensors which adapt individual sensor power and ground line. The second sensor monitors the first sensor and its output voltage is half of the first one. If the ratio of the sensor 1 and 2 is out of the range (approximately 1/2), the diagnostic system judges that it is abnormal.

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.
