A year ago I had replaced what I thought was all of my Pressure Control Valves on my #ford #Focus. Today, I discovered that a third valve was hiding behind another valve that I had changed. I have posted a link to the Vacuum schematic that I by chance found while scouring the internet.
The link to the Vacuum diagram for the Ford Focus:

Thank you so much for posting this! After I did the 8th oil change two days ago, I connected the hoses in a wrong way. I found that diagram too, but seeing you explain it on the car makes it much easier. In my case, one tip of one of the 2 T connectors has no hose. I guess I will have to search for it down below. Your car is in better condition than mine, no big oil leaks, so easy to see al the parts and working on them.
@ciutacu Hey, thanks for your comment. I am so happy that this helped you. I too will be driving my Ford till it falls to bits. I will be posting a video soon explaining how I think the throttle body works.
I've looked high and low for this and not been able to find it I really appreciate you sharing this I have the same engine and I have a boost issue you don't by any chance know where the fuel pressure sensor is located
Hi Fordyuk26, thank you for your comment. I believe the fuel pressure sensor is on the fuel rail. It is also difficult to see. It is on the bottom of the fuel rail roughly between the fuel injector pipes of cylinders 2 and 3. I hope this helps.
Interesting video. I have the same engine in my 2007 Mondeo, however on those it only has one inlet, with two pressure control valves to the right of the engine.
Interesringly, my engine has a knock sensor just under the fuel rail, but no wires going to it! Any idea where the wires should run from?
Hi Rik, thanks for your comment. If you have the same engine then it is most probably DW10 PSA engine. On my engine it has two inlets as the turbo is at the back of the engine. I will do a video on that, but at the moment I am working away. I could not see such a sensor under my fuel rail. I will look though. Were they even fitted with such a sensor? I know the engines on the Focus and Mondeo look the same, but I think there were a few differences.
Have you done the glow plugs yet 😂😂😂😂 you will love them egr and cooler must be removed 😢😢
Hi Karl, thanks for the comment. Yes,I have done the glow plugs and the egr at the same time.For anyone wanting change these items, I suggest being blind folded for 2 weeks before hand and learning to do little jobs in the dark. I would also suggest learning to bend over backwards. As you a fewer words pointed out, they are bastards. 🤣🤣🤣
@@knockittogether-kit that fuel injector return unit is a heat sensor the plug part comes off the pipe unit just a sensor and 3 holes for pipes just taking fuel pump on vacuum pump off changed all sensors crank cam and few other things it fucking refuses to start 15 times cranking then will go then checked live data no codes new good battery 2.2 kw starter at a loss o and had new fusebox
@@karlbigmore7949 OK, iI had a problem like this and it turned out to be the solenoid on the low pressure side of the pump. Check to see if that thing is opening.If it is not you will be cranking till the cows come home.
@@karlbigmore7949 You could also check this by loosening off an injector pipe and cjecking for diesel.
What was your problem with car and what symptoms it has ? I have problem with no getting turbo boost on this engine with error code P0299 car is running like it have 60bhp instead of 136bhp I changed that Y piece on intake also I put a new hose from intercooler side, cleaned EGR and check all of those vacuum pipes and nothing seems to work
Hi @alantir666. Try the following, reset the fault and disconnect the turbo vacuum pipe, test drive and see if you get another error. After that connect the turbo vacuum pipe directly to the vacuum by passing the valve. This is a good way to test the turbo vacuum diaphram and the Vacuum solenoid / switch.
@@knockittogether-kit Thx for reply I already change solenoid witch going to turbo actuator but I found side of pipes witch control hot air intake are leaking some where can it be possible that solenoid can have leak ? also that black tank in system right under that Y piece of intake can it leak somewhere ?
@@knockittogether-kit I solve a problem it was that zip tie witch were holding those pipes together over time pipes gets soft and zip tie mash them together so it restrict amount of vacuum going into the solenders
@@alantir666 Cool that you found the problem. Somtimes it is something silly which can cause a car to run badly.
@@alantir666 There are three solenoids in the system if it is the same as mine. If one or both of the other solenoids are faulty, then you may not be getting the needed vacuum required.
Hi
What was the problem to change those solenoids?
Morning, they were very difficult to get at and I did not know that the Solenoid was buried underneath the other solenoid. It is attached to the under side of the plate. That document is the only reference I have found relating to the Ford Focus Vacuum system.
@@knockittogether-kit But what was the problem with the car?
@@Ray-om5xt Hi, the problem I had was that as the valve was old and malfunctioning, it was no longer holding the vacuum which would was causing a whistling sound and problems with the turbo operation. This valve also controlled the anti shudder valve.
@@knockittogether-kit Hi anti judder valve? I've never heard of that, mine used to judder under acceleration. My exhaust has broken at the flexible pipe and now I have poor performance but no juddering.
How does the anti judder work?
@@Ray-om5xt Sorry mate, my mistake. That should be shudder valve. It helps when turning off the engine by cutting off the air supply.
