Hyundai Genesis (DH): Engine Control System / Barometric Pressure Sensor (BPS) Description and Operation

Hyundai Genesis (DH) 2013-2016 Service Manual / Engine Control / Fuel System / Engine Control System / Barometric Pressure Sensor (BPS) Description and Operation

Description
Barometric Pressure Sensor (BPS) is a speed-density type sensor and is installed on the air cleaner assembly. It senses absolute pressure of the air cleaner assembly and transfers the analog signal proportional to the pressure to the ECM. By using this signal, the ECM calculates the intake air quantity and engine speed.
The BPS consists of a piezo-electric element and a hybrid IC amplifying the element output signal. The element is silicon diaphragm type and adapts pressure sensitive variable resistor effect of semi-conductor. Because one side of the silicon diaphragm is 100% vacuum and the other is affected by the manifold pressure, this sensor can output analog signal by using the silicon variation proportional to pressure change.

    Inspection If idle rpm is unstable or engine stops, check the ETC module operation with GDS diagnostic tool. And if necessary, clean carbon in the throttle body.

    Specification Pressure (kPa)Output Voltage (V)10.00.5055.02.21100.03.93115.04.50

    Description The auto defogging sensor is installed on front window glass. The sensor judges and sends signal if moisture occurs to blow out wind for defogging. The air conditioner control module receives a signal from the sensor and restrains moisture and eliminates defog by the intake actuator, A/C, auto defogging actuator, blower motor

    Inspection 1. Turn the ignition switch OFF. 2. Disconnect the intake actuator connector. 3. Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4. Verify that the intake actuator operates to the recirculation position when connected in reverse.
