Engine Control System / Description And Operation
Description
If the Gasoline Engine Control system components (sensors, ECM, injector, etc.)
fail, interruption to the fuel supply or failure
to supply the proper amount of fuel for various engine operating conditions will
result. The following

Removal
Disconnect the vapor hose (A).
Remove the PCV valve (B).
Inspection
Insert a thin stick (A) into the PCV valve (B) from the threaded side to check the plunger movement.
Warning
If the plunger does not move (PCV
Safe Exit Assist (SEA)
After the vehicle stops, when an
approaching vehicle from the rear area
is detected after a passenger opens the
door, Safe Exit Assist will warn the driver
with a warning message and an audible
warning to help prevent a collision.
