Throttle Full Open Switch: Adjustments

Throttle Switches





Check the idle switch by checking for continuity at connector terminals 1 and 2. The circuit should be closed when the throttle is at rest, switching open as the throttle is opened slightly. To precisely check or adjust the idle switch, open the throttle valve about half-way and slowly let it close. The idle switch should close, completing the circuit, when the gap between the throttle valve lever and its stop is 0.15 to 0.4 mm (.006 to .016 in.). Check the gap with a feeler gauge as shown in image above.
