My 1994 Camry 22.2L 5SFE Power Steering Pump has an Idle-Up feature requiring air connection to the pumps Air Control Valve

This is a problem about finding a new power steering pump With That Connection. Searches find pumps that do not have the connection. Toyota dealers want too much. I can't find pump with it.
Any ideas for good source with one besides dealers?

Any ideas? Guess it could go without but the Idle-Up would not occur during turns to compensate power dips.

 

What is the problem with the current pump?

Have you tried auto salvage yards? Years 1992 to 1996 use the same pump.

 

Thanks for reply toyomoho.

It squeals when turning to extreme direction, or close to extreme. Maybe that's what they call lock to lock (not sure term meaning)?

Not certain as I have bad oil leak too. Think it's oil but might be the PS pump, ATF fluid.
Need to make sure of that though,sorry not certain yet. PS reservoir level not dropping but oil dip stick is.

Just finished re-gasket valve cover, but still see drips. Investigating for Oil Pump leak next.
All said, I might not even have a bad PS pump but just extreme turn squeaks are my only PS symptom.
Hope I don't, cause can't find pump with the air valve. Find only cheezy rebuilts online with no air valve.

 

Is the pump squealing or the belt?

Could be the oil bypass valve in the pump is sticking. Read up on cleaning this.

Something changing the PS fluid will fix things. Suck out all the fluid from the reservoir and refill with new. Drive then repeat the process until the fluid is clear.

The PS should use Dexron III or its generic replacement called something like "ATF fluid." The internet has threads on Dexron III replacements.

 

Thanks Joey P.
It's not the belt but hydraulic sys and manifests by stiffening and resisting.
Failing the expected consistent smoothness, but mostly just on turn extremes.
Sounds real good. Be a bit to get to that but I'll report back when done.
Thank you sir. Rod

 

Is this an intermediate problem? If so, had the same issue years ago. Kept changed the PS fluid in the reservoir until clean and the problem eventually went away not to return.

Guessing the bypass valve was sticking.
