Ford Fiesta Focus 1.0 EcoBoost - Low Power - P132B - How To Test Turbo Control 

Knocking them out now mate 👌 Fantastic Diag & Repair 👍

Great case study. Good methodical approach to diagnostics

Perfect video, nice that you showed the diagram of the turbo and vacuum lines. Have a similar issue with my fiesta. Already checked the turbo and it looks fine, along with all my induction hoses. I think I'll try this out. Thanks a lot

The vacuum pump valve, diaphragm was shot to bits on mine, but I followed you video to check the diagnostics, which I'll have to check again when I fix it, I think I've sourced just the diaphragm alone for just under £15 🤞 Great work content like yours helps us save a few quid during desperate times

Great vid keep up the good work 👍

Great Diag SY, thanks for sharing

You can get the check valves separately now! Good video

Great diag. Thanks for sharing! 👍

Brilliant video again

Cracking vid, cheers.

Great vid Steve 👍

Great find thanks for sharing 👍

Great diagnosis and fix 👍👍

Thanks for this video!

Enjoyed that one mate..... top job 👍🏻👍🏻

Amazing vid. thanks

Thank you for teaching us how the computer controls the vacuum control solenoid which controls the turbo. Sincerely...

I love the diagnostic process you utilize. Very educational.

Absolute stunning mate and i like ur voice!!!

very good video,use this to fix a 20 dti zafira,very poor boost ,tested ecu to boost solinoid and got a switch earth ,opcom could power up solinoids too,applied vacum with a hand pump too,got waste gate to move and hold posistion ,all what was left was the pipes and the pump,pipes held vac and i tried vac pump on pump,did same as yours ,back forth on dial,but i not know that was a bad thing ,after watch this vid ,tried vac test on another zaf a dti and gauge held steady ,hold vac,your vid was the key to moving forward,swop out pump and zaf pulls like a train now ,got live data in opcom too,never thought of check there ,see what the ecu see,from its sensors ,cheers buddy ,keep up the good work ,i have fixed 3 transits now too,and got forscan ,from watching you,and a usb oscilloscope too,for my laptop,boss thinks its strange now i have started fixing more cars ,vans,told him i got a good teacher ,night school,

Excellent vid, crazy you cant get this valve separately.

Why do customers bring a car in for service with an empty fuel tank?

I would be stupid if I didn’t subscribe…..best best….looking for word to learn more thanks

Nice one mate. What’s the world coming to when you need to service your car regularly, they just don’t make em like they used to 🙄

My check valve was broken too. Tested it also on work bench but no need to remove the pump. Fitted an in-line 4mm dia hose check valve for the grand total of £5. At 2k rpm before fitting check valve I got vacuum pressure of 10inHg and after I got 20inHg!

Currently we are having this problem and hopefully changing the vacuum pump will stop the short circuit 🙏🙏

Thats a good bit of boost for a small engine.... I bet the brakes were a lot sharper to with restored vacuum.

the diaphragm he replaced the whole vac pump to fix can be found of under £10 on Ebay. the dead giveaway is that the wastegate actuator rod can be seen flapping about at idle when the engine is running. its just a case of pulling the hose out of the plastic diagram removing a T25 screw and inserting a new one then reconnecting the pipe. you may also want to wash about the BCS on the side of the engine as it can have oil in it that has been pushed into it because of the failed diaphragm so a shot of brake clean in the 3 ports and shaking out the oil inside before reinstalling it can fix the issue.

Thanks for the informative video SY Diagnostics, im hoping you or someone else can help me, i have found i have this issue and upon looking have confirmed the check valve inner rubber umbrella diaphragm membrane piece is broken/disintegrated, i tested with a good working valve from a friends car same car/engine and it solved my issue , so im looking for a replacement inner rubber umbrella membrane diaphragm for inside , does anyone know where i can buy one cheap in the UK ? failing that i have found an inline Brake Servo Non Return Valve Check One-Way Brake Booster Vacuum valve online. The specs for this valve are Valve Opening (Cracking) Pressure:

go a problem with same engine. got good vacuum from pump ( fitted new one way valve ) but it throws p132b :21 code and has loss of turbo power. ive swopped out the solenoid (2nd hand ) and its the same . Ive fited new map sensor and got voltage at the solenoid but it wont send vacuum signal to the waste gate. ( checken all hoses and smoke tested it ) Im stumped now . any ideas ? thanks for your great content .

Love the videos. I've managed to fix this fault with fitting a non return valve from a brake vac hose into the vac feed pipe to the boost control solenoid. Much better than a £300 pound vac pump. Hope that helps someone.

Heyy, I am experiencing the same issue on my Focus ( 1.5 Ecoboost engine ) 150 ps version ; can you help me with the part number for the Vacuum pump and how much did it cost you ? The dealer here refuse to give me the part number; And this engine is not on every market , so I don't know if my vacuum pump is the same as the Kuga ( Escape ) or Fusion with the same engine or even the 1.0 Focus . Thank You.

Troubleshooting path for 1.6 tdci fiesta could be same as here?

what if the vacuum is good at the pump but herratic at the turbo actuator ? should i fisrt try a new solenoid? there is no leak in vacuum lines

Debris in gauze filter usually wet belt starting to break up. Customer should be advised to check this as its a very common issue

I have been following this video with interest watched it a few times to get my head around it. Our 1.0 focus is down on power and there is hardly any vaccum on the pump. It seems to send out an oily mist at the same time pulsates if that make sense. We replaced the one way valve got one of ebay but it lasted a month. We have forscan that gives the same boost reading that you were showing shows a negative reading as the engine if revved. Looks like it needs a new vac pump, Worst engine I have ever owned poor sytem with the wet belt we have had that done after it broke but we were able to get it fixed.

Nice job mate can you help me P2307 Ignition coil C, primary circuit - circuit high P2308 Ignition coil B primary circuit - circuit high I fitted all new spark plugs and 2 new coils car is still the same misfiring bad do u think it might be bad camshaft sensor fault u can start the car a rev it lightly let the pedal go engine cuts out thanks

Can this broke valve give a rich mixture? Thank you!

1st boom:-)

This video has been great help for me, thanks! My turbo was broken and had to replace it, with new turbo I still get codes P132B and P006A.. Car is not working at all.. Checked the vacuum pump and it is holding vacuum. At idle it is giving 20psi vacuum, but when I press brake few times the vacuum goes to 0 and then is slowly going back to 20psi.. Should there bee strong vacuum all the time when motor is running? Should I replace my vacuum pump?

I have the same engine what's turbo wastegate at idle

Hey bud.. Notice that you are using vcmm scope. How do you like it compare to other scopes you may have used? Notice any things you cant use it for?

I have a P0238 error code on my 1.0l fiesta Turbocharger Boost Sensor A Circuit High which presents similar symptoms. What should i inspect first?

Great video, I found this searching for the same error code on 2012 fiesta 1.4 tdci euro 5 engine,, would you know if this has the same turbo vacuum pump to check for ? I do not have access to the testing equipment and am pretty sure after checking what I can that my problem could very well be the same if mine is the same set up at the ecoboost ? I appreciate reply in advance, ohh and my car is smoking badly when driven but smokes like made when driven! a sign of turbo malfunction also i believe, but does seem to boost when revs get to 3000

Regarding my earlier comment I see the smoke testing kit is expensive! I think I'm out my depth, some of it looks simple enough, checking the pump for damage, maybe checking the pressure. I ought to start at the beginning with the live data see what I get, that I should be able to manage.

Where abouts are you located ? I have a 1.4 tdi 2011 with same code but it's come up twice same as yours and the other says Turbo charging pressure sensor circuit signal outside lower limit , any ideas ?

great fix. but what is the cause for the debris on the gauze filter? maybe the timing belt?

I guess the check valve on the pump would stop any major vacuum fluctuations as the pump turned, unlike the test with the original pump where the needle was a blur in the vacuum gauge.

Where about you located mate i have the same problem with my ford focus 1.0 ecoboost 13 reg... and everyone is telling me is the turbocharger have to be changed...

I have the very same issue.....check valve was replaced(volvo sell it seperate) new recirculation valve and no leaks....any more ideas ?

Hi where did you find the turbo diagram?

I have pending DTC code p132b (21) and I'm looking to save some money and hopefully diagnose the problem myself (total novice) Lets be fair it's £45 just to get the diagnostics on it to tell you you've got a problem (I know already) what tools are required and are they expensive? I see a pressure gauges are required, Ive seen a kit at Toolstation and others for £20 or less are these adequate? How much is the smoke testing gear? is there anything that I shouldn't attempt? I have seen elsewhere that shot diaphragm can be a a route cause, and that's just undoing one bolt to check that ain't it? We are all just trying to save a few quid times are hard! I've only had the vehicle a few months 😭Been serviced regular, full MOT no advisories, vehicle health check at Perrys 31/03/2022 engine timing check required and fixed (£392.47) and a pre delivery inspection carried out 07/04/2022 (Turbo charger operates ✅Hoses lines and fittings ✅ wiring and cables ✅ Am I just unlucky? Sorry it's long winded, but I NEED HELP! Thanks in advance

you timing belt is in dissolution, thats the reason why your filter on your vacuumpump is blocked/clogged. Wrong engin oil used in this car

Pierburg boost control non-return valve Audi VW Skoda Seat 7.05817.00 046905291A giving one of these a try 🙏🏼

Did you by chance notice oil on the "check valve" of the vacuum supply (ie. 7:52) before taking the vacuum pump off? I have a 2014 Fiesta with exactly the same symptoms and also oil on the vacuum pump around the area where this valve goes in. here's a picture - imgur.com/a/XYF4yUy

Typical, no fuel!
