Idle Speed: Adjustments
FIXED SPEED ADJUSTING SCREW (SAS) ADJUSTMENT
NOTES:
1. The fixed SAS should not be moved unnecessarily; it has been precisely adjusted by the manufacturer.
2. If the adjustment for any reason is disturbed, readjust as follows.
Procedure
1. Loosen the tension of the accelerator cable sufficiently.
Fixed SAS Adjustment
2. Back out the fixed SAS lock nut.
3. Turn the fixed SAS counterclockwise until it is sufficiently backed out, and fully close the throttle valve.
4. Turn the fixed SAS clockwise until the throttle lever is touched (i.e., the point at which the throttle valve begins to open) is found. From that
point, turn the fixed SAS clockwise another 1 1/4 turn.
5. While holding the fixed SAS so that it doesn't move, tighten the lock nut securely.
6. Adjust the tension of the accelerator cable.
7. Adjust the basic idle speed as directed below.
8. Adjust the closed throttle position switch and throttle position sensor.
BASIC IDLE SPEED ADJUSTMENT
NOTES:
1. The standard idle speed has been adjusted, by the engine speed adjusting screw (SAS), by the manufacturer, and there should usually be no
need for readjustment.
2. In case the adjustment is disturbed or when the idle speed is too high or it drops owing to application of air conditioning load, make adjustment
by the procedure described below.
3. The adjustment, if made, should be made after first confirming that the spark plugs, the injectors, the idle air control motor, the compression
pressure, etc., are all normal.
Procedure
1. The vehicle should be prepared as follows before the inspection and adjustment.
^
Engine coolant temperature: 80-95°C (176-203°F)
^
Lights, cooling fan and accessories: OFF
^
Transaxle: Neutral (A/T for P range)
2. Connect the scan tool to the data link connector (white).
NOTE: When the scan tool is connected, the diagnostic test mode control terminal should be grounded.
If a scan tool is not used, follow steps a-c:
