Idle Air Control Valve

Hi,

Is it possible to clean the Idle Air Control Valve to get them to work properly or is it better just to buy a new one. I see it's a sensor of sorts since there's an electrical connection.

Also, does the Mass Air Flow sensor go bad. I cleaned it and re-mounted it. I'm getting no fault readings on the Mass Air Flow sensor. I do have an Idle control issue according to fault P0505. I'm looking at all the air and fuel control sensors. I just got my new Idle position sensor.

Up to you one can try and Clean Things.

Myself depending on age already 20 plus years old till you take things all apart to clean it I will get a New One.

 

yes it’s possible to clean, most often best to remove and clean it.
Not a sensor, it takes information from other sensors and try’s to maintain target idle speed.
MAF sensors do go bad.
No such thing as an idle position sensor, might you be referring to a throttle position sensor?

 

No, to diagnose a problem, it's a voltage check. If it's out of range, manual recommends to replace it.

For P0505, check for vacuum leaks first.

 

^^ You might try squirting a little QuikStart or some such around the end of the hose that connects to the IAC. Not too much, just a quick little spurt.
I write this because although the rubber hose connection appeared to be sealing, it wasn't. Nor was there any clamp around it. I took a good look at it and didn't see anything wrong with it, but after I put a hose clamp on it my problem went away.
