gen3 3sgte iacv problem Options

[match220]

So I've narrowed down my previous post "gen III 3sgte runs for 5 seconds and shuts off" to the problem. The iacv isn't fully engaging and I can hear the solenoid clicking about 10 times a second because it can't turn the valve. I took the solenoid part off (held by two screws) and tried to manually turn the metal stub in the TB...it turns but it is hard to turn and there was a little rust build up. I'm not sure if the solenoid is old and worn and can't turn the valve, or if the valve is stuck because it's old and it can't be turned by the solenoid. Either way, it's not moving. I tried spraying some lubricant and it didn't seem to help. Is there a replacement part that I can use instead of the gen3 3sgte one? Or do I have to try to find a gen3 iacv? I didn't see the IACV in the gen3 parts list, but I thought I would ask anyway. Part number on the white solenoid part is 22270-74230. I have a 22270-74290 off of a 5sfe (either 98 camry or 95 celica) that I can play around with and I should have another one off of another 5sfe (either 98 camry or 95 celica). I read in another post that there is a 22270-74210 that will fit too. Have you guys tried swapping these out? Do they function the same even though the part numbers are different? And is only the solenoid swappable or is the valve part swappable too?

Hi there ,

I see you post on the autronic forum . First you have to know that idle valve control is not mandatory and may not be full compatible with the sm4 .

Disconnect your iacv and try to get 3-4 % opening on your throttle body . (adjustable bolt or cable adjustment ?)

With this permanent opening you should be able to get your engine run with proper fuel and timming .

Do you have sync error ?

I have oversize throttle body with little opening (which is my 0% on autronic tb setting) and with the idle timming table on the autronic my 1.8L engine idle very well.

You should try permanent opening and idle timming table .

Thanks, I played around with the car more and got it running today. But it idles dangerously high now (4k rpm), so I don't let it run for long. The IACV should be able to function on the SM4, I've been told how to configure them on toyotas, but it still isn't working properly. Tomorrow I'll unplug it and see how it will perform. When I was rebuilding it I noticed it was partially open when off, so it will be a boost leak when disconnected. I might have to plug the hose.
