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 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.
3) If idle mixture has been adjusted, confirm that idle speed is with-
in specification.
