PCV Valve Removal and Installation

S6JB0B1206007

Removal

1) Disconnect PCV hose from PCV valve.
2) Remove PCV valve from cylinder head cover.

Installation

1) Apply sealant to thread part of PCV valve (1).

“A”: Water tight sealant 99000–31250 (SUZUKI
Bond No.1207F)

2) Install PCV valve (1) onto cylinder head cover.

Tightening torque
PCV valve (a): 27 N·m (2.7 kgf-m, 19.5 lb-ft)

3) Connect PCV hose (2) to PCV valve (1).

PCV Valve Inspection

S6JB0B1206008

NOTE
Be sure to check that there is no obstruction
in PCV valve or its hoses before checking
engine idle speed / IAC duty for obstructed
PCV valve or hose hampers its accurate
checking.

1) Remove PCV valve referring to “PCV Valve Removal

and Installation”.

2) Connect PCV valve (1) to PCV hose and plug head

cover hole.

3) Run engine at idle.
4) Place your finger on the hole of PCV valve (1) to

check for vacuum. If there is no vacuum, check for
clogged valve. Replace as necessary.

5) After checking vacuum, stop engine and remove

PCV valve (1). Shake valve and listen for the rattle of
check needle inside the valve. If valve does not
rattle, replace valve.

6) After inspection, remove plug from head cover hole.

Then, install PCV valve to head cover hole referring
to “PCV Valve Removal and Installation”, connect
PCV valve, PCV hose and clamp securely.

referring to Step 1) to 11) of “Intake Collector and
Intake Manifold Removal and Installation in Section
1D”.

2) Remove EGR valve (1) and gasket from intake

collector (2).

Installation
Reverse removal procedure noting the following.

EGR Valve Assembly Inspection (If Equipped)

S6JB0B1206010

1) Check resistance between the following terminals of

EGR valve (1) in each pair.
If found faulty, replace EGR valve assembly.

EGR valve resistance
Terminal “A” and terminal “B”: 20 – 24

Ω at 20 °C

(68

°F)

Terminal “C” and terminal “B”: 20 – 24

Ω at 20 °C

(68

°F)

Terminal “F” and terminal “E”: 20 – 24

Ω at 20 °C

(68

°F)

Terminal “D” and terminal “E”: 20 – 24

Ω at 20 °C

(68

°F)

Terminal “B” and valve body: infinity (

∞)

Terminal “E” and valve body: infinity (

∞)

2) Remove carbon from EGR valve gas passage.

NOTE
Do not use any sharp-edged tool to remove
carbon.
Be careful not to damage or bend EGR valve,
valve seat and rod.

3) Inspect valve (2), valve seat (3) and rod for fault,

cracks bend or other damage.
If found faulty, replace EGR valve (1) assembly.

Repair Instructions

Engine Control Module (ECM) Removal and
Installation

S6JB0B1306001

CAUTION

!

As ECM consists of precision parts, be
careful not to expose it to excessive shock.

NOTE
If ECM is replaced with new one or with
another one, make sure to register
immobilizer transponder code to ECM
correctly according to “Procedure after ECM
Replacement in Section 10C”.

Removal

1) Disconnect negative cable from battery.
2) Remove ECM cover from bracket.
3) Disconnect connectors from ECM as follows.

a) Push lock (1) to release locking of lock lever (2).
b) Turn lock lever to arrow direction until it stops.

4) Remove ECM (1) from its bracket by removing its

mounting bolts (2).

Installation
Reverse removal procedure noting the following:
• Connect connectors to ECM as follows.

a. Make sure that lock lever (1) of ECM connector is

at unlock position.

b. In this state, insert connectors to ECM securely.
