Hyundai Venue: Air Conditioning System / A/C Pressure Transducer. Description and operation
The A/C Pressure Transducer (APT) converts the pressure value of high pressure
line into voltage value after measuring it. By converted voltage value, engine
ECU controls the cooling fan by operating it high speed or low speed. Engine
ECU stops the operation of the compressor when the temperature of refrigerant
line is very high or very low irregularly to optimize air conditioning system.

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.
