D27DTP/D27DT (EU4)

1. OVERVIEW AND SYSTEM LAYOUT

For the vehicle equipped with D27DTP (POWER UP) engine, the switchable engine mount system lets the engine
ECU electronically control the shock absorber’s characteristics in the engine mount.

This system can control the vacuum in two modes (soft and hard) through the engine ECU to minimize the noise and
vibration and improve driving comfort and stability.

• The components of vacuum sole-

noid valves are the same in vari-
ous types of engines. However,
their functions are different from
each other. The vacuum solenoid
valve for D27DTP (POWER UP) en-
gine controls the vacuum in the en-
gine mount. The vacuum solenoid
valve for D27DT engine controls
the vacuum in IWE (Integrated
Wheel End) of 4WD system.
