1. OVERVIEW AND LOCATION

The location and the specifications of boost pressure sensor for the D27DTP (POWER UP) engine are changed due
to the mounted VGT turbo charger and additional throttle body.

BOOST PRESSURE SENSOR

Location

The boost pressure sensor is piezo-electric element type and consists of three terminal. It determines the injection
timing and calibrates the injection volume depending on the intake air. Also, it determines whether to stop the EGR.
