Kia Cadenza YG: Engine Control System / Barometric Pressure Sensor (BPS) Description and Operation
Kia Cadenza YG 2016-2021 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 assemby. It senses absolute
pressure of the air cleaner assemby 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 100% vacuum and the manifold pressure apply to
both sides of the sensor respectively, this sensor can output analog
signal by using the silicon variation proportional to pressure change.
Inspection Throttle Position Sensor (TPS) 1. Connect the GDS on the Data Link Connector (DLC). 2. Start the engine and measure the output voltage of TPS 1 and 2 at C.
Specification Pressure [kPa (kgf/cm², psi)]Output Voltage (V)10.0 (0.01, 0.15)0.5055.0 (0.56, 7.98)2.21115.0 (1.17, 16.9)4.50
