IDLE MIXTURE INSPECTION / ADJUSTMENT
(VEHICLE WITHOUT HEATED OXYGEN SENSOR)
All vehicles not equipped with heated oxygen sensor are shipped
with their CO% factory adjusted as follows.
Engine idle mixture
(CO%)
0.8 – 1.3% at specified idle speed
Idle mixture adjustment should never be changed from the original
factory setting. However, if during diagnosis, the check indicates
idle mixture to be the cause of a driver performance complaint or
emission failure, the idle mixture can be adjusted using the follow-
ing procedures.
NOTE:
For this inspection and adjustment, exhaust gas tester (CO
meter) and engine tachometer are necessary.
1) Check idle speed according to “IDLE SPEED / IDLE AIR CON-
TROL DUTY INSPECTION” section.
2) Using exhaust gas tester, check that idle mixture CO% is within
above specification. If it is out of specification, adjust it to specifi-
cation by turning resistor knob (1).
3) If idle mixture has been adjusted, confirm that idle speed / IAC
duty is within specification.
