Yes it can be cleaned. Normally it is just carbon clogging it up. Do a search and you will get many answers.

Are there any known problems with the Idle Air Control valve in 97 Maximas? This appears to be my problem. Also is there a way to clean it given that a new valve is $200? Please help.

The credit goes to Mango95SE for this procedure.
Tools needed:
10 and 12 mm sockets
3 inch socket extension
universal joint (swivel pivot socket thing)
12-inch rachet (a short rachet may not work - need something to apply a lot of torque to loosen the bolts
Philip's screwdriver
rag
throttle body cleaner
1. Unplug the 4 connectors from the IAC assembly. Undo the hose that connects teh IAC to the intake assembly.
2. The metal bracket holding up the gray-colored connector is blocking one of the IAC mounting bolts. Using a 10mm socket, remove the bolt that holds the metal bracket. The bolt is just below the purple connector - you have to twist your head and crane your neck around to see the bolt.
3. Remove the 3 mounting bolts using the 12mm socket. The lowest bolt may require the Universal joint.
4. Pull out your IAC valve and clean it w/throttle body cleaner, rag, and old toothbrush.
You may even want to separate the plastic valve to clean it more thoroughly. Use a philip's head screwdriver, but make sure it is a snug fight. It's on there tight and if you don't have a good fitting screwdriver, you could ruin the screw head.
Reinstallation is just the reverse of these steps. It may be easier access to the IAC if you remove the whole air intake assembly, but it's not necessary.
So if the reading is zero over these terminals (I looked it up in the service manual) the control valve is bad?

if you have an ohmmeter you can easure the resistance. I'll have to show you how to do this, but you should be seeing 30 ohms in terminals:
1-2
2-3
3-4
5-6
hope that helps.

After cleaning the IAC now my service engine light comes on. Is there any way to reset this?

Idle Air Control
I checked my idle air control and got zero ohms over the terminals shown in the manual. Is the valve bad? I turned the ignition switch to on and it moved. I cleaned it and put it back together and it seems to work fine. Also, when I put it all back together the service engine soon light came on. I think having some of the plugs undone when I turned the ignition on triggered it. Is there any way to reset the service engine soon light? Thanks.
