valve checking procedure.
Fuel Evaporative Emission Control System 
Inspection
S7RS0B0206014
1) Visually inspect hoses for cracks, damage, or  excessive bends. Inspect a ll clamps for damage and 
proper position.
2) Check EVAP canister for operation and clog,  referring to “EVAP Canister  Inspection in Section 
1B”.
If a malfunction is found, repair or replace.
Brake Discs and Pads InspectionS7RS0B0206015
1) Remove wheel and caliper but don’t disconnect  brake hose from caliper. 2) Check disc brake pads and discs for excessive wear, 
damage and deflection. Replace parts as necessary. 
For details, refer to “Front Disc Brake Pad Inspection 
in Section 4B”, “Front Brake Disc Inspection in 
Section 4B”, “Rear Disc Brake Pad Inspection in 
Section 4C” and/or “Rear Brake Disc Inspection in 
Section 4C”.
Be sure to torque caliper pin bolts to specification.
Brake Hoses and Pipes InspectionS7RS0B0206016
Perform this inspection where these is enough light and 
use a mirror as necessary.
• Check brake hoses and pipes for proper hookup, leaks, cracks, chafing and other damage.
• Check that hoses and pipes are clear of sharp edges  and moving parts.
Repair or replace any of these parts as necessary.
CAUTION! 
After replacing any brake pipe or hose, be 
sure to carry out  air purge operation.

EVAP Canister InspectionS7RS0B1206006
WARNING! 
DO NOT SUCK nozzles on EVAP canister. 
Fuel vapor inside EVAP canister is harmful.
 
1) Check outside of EVAP canister visually.
2) Disconnect vacuum hoses from EVAP canister.
3) Check that there is no restriction of flow through purge pipe (1) and air pipe (2) when air is blown (4) 
into tank pipe (3).
If any faulty condition is  found in this inspection, 
replace EVAP canister.
EGR Valve Removal and InstallationS7RS0B1206007
Removal
1) Disconnect negative (–) cable at battery.
2) Remove air intake pipe.
3) Remove EGR pipe.
4) Disconnect EGR valve connector.
5) Remove EGR valve and gasket from cylinder head.
Installation
Reverse removal procedure noting the following.
• Clean mating surface of valve and cylinder head.
• Use new gaskets.
EGR Valve InspectionS7RS0B1206008
1) Check resistance between following terminals of  EGR valve (1) in each pair.
If found faulty, replace EGR valve assembly.
EGR valve resistance (A – B, C – B, F – E, D – E 
terminal)
20 – 24  Ω
2) Remove carbon from EGR valve gas passage.
CAUTION! 
Do not use any sharp-edged tool to remove 
carbon.
Be careful not to damage or bend EGR valve 
(1), valve seat (3) and rod.
 
3) Inspect valve (2), valve seat and rod for fault, cracks,  bend or other damage.
If found faulty, replace EGR valve assembly.
PCV Hose InspectionS7RS0B1206009
NOTE
Be sure to check that there is no obstruction 
in PCV valve or its hoses before checking 
IAC duty, for obstructed PCV valve or hose 
hampers its accurate adjustment.
 
Check hoses for connection, leakage, clog and 
deterioration.
Replace as necessary.

PCV Valve InspectionS7RS0B1206010
NOTE
Be sure to check that there is no obstruction 
in PCV valve or its hoses before checking 
IAC duty, for obstructed PCV valve or hose 
hampers its accurate adjustment.
 
1) Detach air cleaner assembly.
2) Disconnect PCV valve from cylinder head cover and install plug to head cover hole.
