2001 SUZUKI GRAND VITARA Engine removal

6E2-44 ENGINE AND EMISSION CONTROL SYSTEM (SEQUENTIAL MULTIPORT FUEL INJECTION FOR H27 ENGINE)
Emission Control System
EGR system (if equipped)
EGR SYSTEM INSPECTION (USING SUZUKI SCAN TOOL)
1) Connect SUZUKI scan tool to data link connector (DLC) (1)
with ignition switch OFF.
Special tool
(A) : SUZUKI scan tool
2) Start engine and warm up it to normal operating tempera-
ture.
3) With engine idling (without depressing accelerator pedal),
open EGR valve by using “MISC. TEST” mode.
In this state, according as EGR valve opening increases
engine idle speed drops. If not, possible cause is clogged
EGR gas passage, stuck or faulty EGR valve.
REMOVAL
1) Disconnect negative (–) cable at battery.
2) Disconnect EGR valve coupler.
3) Remove wire harness bracket from intake collector.
4) Remove EGR valve (5) and gasket from intake collector.NOTE:
For operation procedure of cartridge, refer to its car-
tridge operator's manual.

INSPECTION
1) Check resistance between following terminals of EGR valve
(1) in each pair.
If found faulty, replace EGR valve assembly.
EGR valve resistance:
2) Remove carbon from EGR valve gas passage.
3) Inspect valve (2), valve seat (3) and rod for fault, cracks,
bend or other damage.
If found faulty, replace EGR valve (1) assembly.
INSTALLATION
Reverse removal procedure noting the followings.
•Clean mating surface of valve and intake manifold.
•Use new gasket.
