2002 Ford Focus SE SPI
Maybe pressure regulator or something? Pressure switch?
Sadly Ive worked on most parts of the car but not power steering yet so I am not sure what this part is. From what I can tell it sort of looks like a pressure valve. At anyrate, mine is leaking out of it and I need a new one! If anyone can help identify that would be awesome! Its spitting foam/power steering fluid out the bottom of that part, its totally corroded away.

It should have an electrical connector on it and look like this:

Perhaps someone disconnected the connector?

Is this where its supposed to be? I cant find that part in that location on anything, did someone just move it?
I looked for a good 15 minutes and could not find any electrical connector dangling anywhere. The corrosion seems to be old, ive had the car 2+ years and never noticed.
If it is the sensor, I am guessing its just unscrew and screw the new one in? Considering I may not have an electrical connector, it seems a quick fix hopefully.
Thanks for the input!
(parts very may well be moved, whoever had it before me added a lot of aftermarket things then removed parts of them but left a lot of pieces)

I figured it was this when turning the wheel with car on, foamy fluid starts coming out of it.

Yes it seems the connector rotted off. Unless somebody cut the harness i think you will find the harnes connector and a part of the switch dangling somewhere.

You need a new power steering pressure (PSP) switch. Ford pn should be YS4Z-3N824-EA or aftermarket equivalent. They actually list two different switches - one with SAE threads and one with metric threads. It says SPI uses SAE threads and that is the pn I gave you.

Good luck

Thanks man!
Was such a let down last night at work to hop in the car, turn it on and hear the screaming groan and whine =/ Thanks!
Could very well be someone cut the harness off or it was already rotted off when I got it. Ill give it another look below for the danging wires but after 2+ years and however long the guy before me had it, it may of fallen/snagged and tore off at some point.
This is so much better news than I was worried it would be, my last Ford I got rid of because buying another of the same year was cheaper than the repair.

I would still try to find the harness connector and replace the switch and re-connect the connector. However if you absolutely cannot find the connector (and its been diconnected and working fine for a long time) you probably can just remove the old leaking switch and plug the hole in the port. The thread is 3/8-24. Go to an auto parts store, etc, and get a plug with the same threads that matches the threads on the switch. The plug will probably cost much less than a new switch.

Good luck

Yeah a new switch is about 60 dollars. I was just going to write and ask if any difference would be made by using a bolt/plug. Started thinking, it says it should throw a CEL,(says that online, I dont get why it would throw a CEL, its not an emissions part) it doesnt seem to. If it doesnt throw a CEL and I cant find the connector the only difference I could think of is that fluid cant come out and leak if the pressure goes up.

I do plan to try and find the connector after work today (have to ride electric scooter home, yay) but at worse, if there is no connector/wiring anymore there is absolutely no reason to spend so much on a sensor, I cant use.

Thanks again for infos! :)
(I did notice the steering was slightly stiffer than I was used to and expecting when I first got the car, (barely resistance when turning when usually it just moves without any effort)I chalked it up to it being a different model of car than I was used to, maybe this explains that)

The PCM will set a DTC for any sensing circuit failure - doesnt have to be emissions related. Not all DTCs result in a CEL illumination. If you have access to a scan tool you can check to see if a DTC has been set for that circuit.

Good luck

No DTC for it, no errors pending or stored at all. Very weird :(
Maybe they bypassed it someway or its still connected to the top of the connector somewhere and thats causing it to work? Will find out after work today in a few hours :)
(I love ForScan)

When it fell of it must of went into the belt area, short wires connector gone! Put a bolt in, still bleeding I needed more fluid
Make sure you insulate the ends of the broken wires.

It looks like the stock switch has a o-ring face seal:

Did you try to use the o-ring from the old switch on your bolt/plug?

Yep original o ring was in good shape and reused it. For now I zip tied the wires out of the way, plan to insulate in the morning before work. There was a lot of air in the system had to go get a 2nd little bottle =/
Thanks again for the help!
