Description and operation
Description

Installed on the intercooler assembly, the Boost Pressure Sensor (BPS) measures the pressure of compressed air in the turbocharger.

The BPS consists of a piezo-electric element and a hybrid IC amplifying the element's output signal. The element is silicon diaphragm type and adapts pressure sensitive variable resistor effect of semi-conductor. One side of silicon diaphragm is 100% vacuum and turbocharger pressure is applied on the other side. Hence, output is gained from the silicon variation in proportion to the pressure change.

Removal
1.

Switch "OFF" the ignition and disconnect the negative (-) battery terminal.

2.

Disconnect the boost pressure sensor connector (A).

3.

Remove the mounting bolts (B), and then remove the sensor from the intercooler outlet pipe.

Boost pressure sensor mounting bolt :

9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)

Installation
  

Install the component to the specified torques.

Note that internal damage may occur when the component is dropped. If the component has been dropped, inspect before installing.

Insert the sensor in the installation hole and be careful not to damage it.

1.

Install in the reverse order of removal.

Kia Stinger (CK) 2018-2023 Service Manual: Fuel Pump Control Module (FPCM)

Description and operation Description Installed on the righthand side of the fuel tank, the fuel pump control module (FPCM) controls the DC motor mounted inside the low pressure fuel pump. The module compares instantaneous fuel pressure information measured by the fuel pressure sensor (FPS) with target fuel pressure information provided by the ECM and generates the desired target fuel pressure by controlling the fuel pump motor and regulating fuel flow rate in the low pressure fuel line between the low and high pressure fuel pumps.
