Description and Operation

Description

The Boost Pressure Sensor (BPS), installed on the intercooler, measures the pressure of the compressed air from the turbocharger.

The BPS consists of a piezoelectric element and a hybrid IC that amplifies the output signal of the element. The element is a silicon diaphragm that is subjected to pressure. Its resistance changes with pressure (piezoresistive effect). One side of the silicon diaphragm is at 100% vacuum, and turbocharger boost pressure is applied to the other side. Therefore, the output produced by the silicon deformation is proportional to the pressure change.

Repair Procedures

Inspection

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

  2. With the ignition switch ON, measure the BPS output voltage at idle.

    [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. Turn the ignition switch OFF and disconnect the negative (-) battery terminal.

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

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