Hyundai Venue: Engine Control System / Accelerator Position Sensor (APS). Description and operation
Hyundai Venue (QX) (2020-2024) Service Manual / Engine Control / Fuel System / Engine Control System / Accelerator Position Sensor (APS). Description and operation
| 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.

Air bag collision sensors
WARNING
To reduce the risk of an air bag deploying unexpectedly and causing serious injury or death:
Do not hit or allow any objects to impact the locations where air bags or sensors are installed. Do not perform maintenance on or around the air bag sensors. If the location or angle of the sensors is altered, the air bags may deploy when they should not or may not deploy when they should. Do not install bumper guards or replace the bumper with a nongenuine HYUNDAI parts. This may adversely affect the collision and air bag deployment performance. Place the ignition switch in the LOCK/OFF or ACC position when the vehicle is being towed to prevent inadvertent air bag deployment. Have all air bag repairs conducted by an authorized HYUNDAI dealer.
