5) After checking vacuum, stop engine and remove

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

6) After checking, remove plug and install PCV valve.
7) Install air cleaner assembly securely.

Repair Instructions

EGR Valve Inspection

S6JB0A1226006

CAUTION

!

Do not disassemble EGR valve, or original
performance will be spoiled.

1) Check EGR valve for the following.

If malfunction is found, replace EGR valve.
• Check EGR valve for wear and damage.
• Check EGR valve operates smoothly by opening

EGR valve fully by hand.

2) Check resistance of EGR valve as follows.

If malfunction is found, replace EGR valve.
a) Check resistances between the following EGR

valve terminals respectively.

EGR valve resistance

b) Check resistance between terminals 2 and 6 is

decreased linearly when opening EGR valve
fully from close position.

3) Check EGR valve operation by ECM signal as

follows.
a) Turn ignition switch to OFF position.
b) Connect EGR valve connector (1) to EGR valve

(2).

c) Turn ignition switch to ON position.
d) Check EGR valve opens and closes each

approx. 10 times repeatedly and automatically
after turning ignition switch to OFF position.

If EGR valve does not operate at all, go to next
step.
If EGR valve operates correctly, EGR valve is in
good condition.

4) Check pulse signal for EGR valve as follows.

a) Disconnect EGR valve connector.
b) Turn ignition switch to ON position.
c) Measure operating pulse signal between

terminal “1” and terminal “5” of EGR valve
connector using oscilloscope after turning
ignition switch to OFF position.
If pulse signal shown in figure can be measured,
replace EGR valve.
If not, check connection and wiring harness
between EGR valve and ECM.
