ENGINE IDLE SPEED
• The engine must be warm for accurate idle speed
inspection.
• When inspecting the engine idle speed, make sure
that the fast idle knob is pushed fully in.
• Use a tachometer with graduations of 50 rpm or
smaller that will accurately indicate a 50 rpm change.
Start the engine and warm it up to coolant temperature
80°C (176°F).
Stop the engine and connect a tachometer according to
the tachometer manufacturer's operating instructions.
Start the engine and let it idle.
Turn the fast idle knob [1] to obtain the specified idle
speed.
Turning the fast idle knob counterclockwise results in a
faster/higher idle speed.
Turning the fast idle knob clockwise results in a slower/
lower idle speed.
IDLE SPEED: 1,800 ± 100 rpm
If engine idle speed can not adjust, check the fast idle
knob.
Refer to an official Honda Service Manual or see your
dealer to check the fast idle knob.
