Check An Idle Air Control Valve

The idle control valve in your vehicle is mounted on the throttle object and controls the air flow into the engine from on all sides of the throttle oppose. The valve, as the term suggests, controls the lazy. When this valve is begrime, your vehicle Testament corner a consolidated generation idling. Research to flash provided the valve is functioning properly by physically examining it. Whether it's blacken, you can Disinfected it; whether it's not soil and your vehicle is idling Rugged, the domination valve may hog failed. You Testament be able to confirm this with a voltmeter.


Pull the lazy clout valve off the throttle intent and turn it over to expose the valve openings.4. Turn the dial on the voltmeter to "Ohms."5.

Unplug the electrical plug running to the direction valve. It may pull fair off, on the contrary you may longing to squeeze the Proceeds tab on the top of the your plug before it Testament come off the borderline of the valve.

3.1. Free the hood and remove the screws holding the idle control valve to the throttle oppose on the back of the engine.2.

Touch one of the leads on the voltmeter to one of the terminals on the edge of the valve. Then, touch the other vanguard of the voltmeter to the other terminal on the extremity of the valve. The reading should be "0.00," but a variance of ".05" is acceptable. If it falls outside of this range, your valve has failed and must be replaced.

6. Check the inside of the valve openings for dirt if the valve passed the ohm test (resistance test). The sensor will be dirty if the valve is otherwise functioning properly.

7. Spray the sensor liberally with electronic parts cleaner and allow the fluid to drain out of the valve openings until it runs clear.

8. Let the sensor dry completely and then reinstall it onto the throttle body. Installation is the reverse of removal.
