6E2-20 ENGINE AND EMISSION CONTROL SYSTEM (SEQUENTIAL MULTIPORT FUEL INJECTION FOR H27 ENGINE)
CLEANING
Clean throttle body bore and bypass air passages (1) by blowing
compressed air.
INSTALLATION
1) Clean mating surfaces and install throttle body gasket to
intake collector (1) with new gasket (2).
2) Install throttle body to intake collector and tighten bolts.
3) Connect PCV hose.
4) Install throttle body and intake collector to intake manifold
with new intake collector gaskets.
5) Install EGR pipe with new gaskets.
6) Connect breather hose and EVAP canister purge valve hose
and install PCV valve to cylinder head.
7) Connect connectors of EVAP canister purge valve, MAP
sensor and EGR valve.
Fix wire harness with clamps.
8) Install clamp bracket to intake collector.
9) Connect ground wire connector.
10) Connect connectors of TP sensor, ground and IAC valve.
11) Install surge tank pipe to intake manifold with new gaskets
and intake air pipe to throttle body. Install surge tank cover.
12) Connect engine coolant hoses to throttle body.
13) Connect accelerator cable and A/T throttle cable (A/T).CAUTION:
Do not blow compressed air through bypass air pas-
sage with IAC valve installed to throttle body. This will
cause IAC valve to malfunction.
TP sensor, idle air control valve or other components
containing rubber must not be places in a solvent or
cleaner bath.
A chemical reaction will cause these parts to swell,
harden or get distorted.

REMOVAL
1) Relieve fuel pressure in fuel feed line referring to “FUEL
PRESSURE RELIEF PROCEDURE” in Section 6-1.
2) Remove throttle body intake collector, refer to “THROTTLE
BODY” in this section.
3) Disconnect fuel feed hose (1) and fuel return hose (2).
4) Disconnect vacuum hose (4) and fuel return hose from fuel
pressure regulator (5).
5) Remove fuel feed pipe (8) and fuel connect pipe (7) from
delivery pipes (6) (right and left).
6) Disconnect connector (3) from each injector.
7) Remove delivery pipes (1) (right and left) from intake mani-
fold.
8) Remove fuel injector(s).
INSPECTION
CAUTION:
A small amount of fuel may be released when it is from
delivery pipe.
Place a shop cloth under delivery pipe so that released
fuel is absorbed in it.
WARNING:
As fuel is injected in this inspection, perform in a well
ventilated area and away from open flames.
Use special care to prevent sparking when connecting
and disconnecting test lead to and from battery.

5) Install fuel connect pipe (1) and tighten union bolts to speci-
fied torque with new gaskets (3).
Tightening torque
Fuel connect pipe union bolt
(b) : 30 N·m (3.0 kg-m, 22.0 lb-ft)
6) Install fuel feed pipe (2) and tighten union bolt to specified
torque with new gaskets.
Tightening torque
Fuel feed pipe union bolt
(a) : 30 N·m (3.0 kg-m, 22.0 lb-ft)
7) Connect vacuum hose (5) and fuel return hose (4) to fuel
pressure regulator.
8) Connect fuel feed hose (1) and fuel return hose (2).
9) Connect connectors of injector wire (3) to injectors.
10) Install throttle body and intake collector, refer to “THROTTLE
BODY” in this section.
11) With engine “OFF” and ignition switch “ON”, check for fuel
leaks around fuel line connection.

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.
