Engine General Information and Diagnosis: 1A-140
6) Check that specified engine idle speed is obtained with A/C ON if vehicle is equipped with A/C.
If not, check A/C control circuits and idle air control system referring to “A/C Control System Check (Vehicle with A/
C)” and “Idle Air Control System Check”.
Engine idle speed and IAC duty
NOTE
Above duty values are ON duty (low voltage rate) meter indications.
Idle Mixture Inspection / Adjustment (Vehicle
without Heated Oxygen Sensor)
S3RH0A1106002
All vehicles not equipped with heated oxygen sensor are
shipped with their CO % factory adjusted as follows.
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 following procedures.
Engine idle mixture (CO %)
0.5 – 1.5% at specified idle speed
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
Control (IAC) Duty Inspection”.
2) Using exhaust gas tester, check that idle mixture CO
% is within above specification. If it is out of
specification, adjust it to specification by turning
resistor knob.
NOTE
Turning CO adjusting resistor knob to “A”
increases CO % (A/F mixture becomes rich)
and turning it to “B” decreases CO % (A/F
mixture becomes lean).
3) If idle mixture has been adjusted, confirm that idle
speed is within specification.
