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.

Repair procedures

Inspection

1.	Connect the KDS on the Data Link Connector (DLC).

Measure the output voltage of the BPS during idle with IG ON.

Pressure [kPa (kgf/cm², psi)]	Output Voltage (V) [Vref=5V]
20.0 (0.20, 2.9)	0.79
46.7 (0.47, 6.77)	1.84
101.3 (1.03, 14.7)	4.0

Removal

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

2.	Disconnect the boost pressure sensor connector (A).

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.
