Peter, I reckon if you did a video of 'Mazda 6 2.2 diesel buyers guide by a mechanic' with links to all the videos you've done previously. You could talk a bit about the history of the model - the year it was introduced etc, the standard features and, importantly, the most common issues, you'd get lots of views.
If I were thinking of buying one of these cars, this sort of information would be extremely useful. I'm sure fellow mechanics would find it very helpful too. Keep up the good work, Peter. Your videos are excellent and with a bit of focus on what would be useful to the masses, I hope you can increase the number views and subscribers etc.
Thank you Ricardo. It nice to be able to know if it’s starting to fail prior to returning it to the customer & then get a call 2 days later with a check engine light on again 😬😬👍

Hi Peter, Good video with lots of details 👌. I have the same error code. Is ut enough to replace the vacuum pump or I need to get other parts checked. Many thanks
If you have a scantool look at brake booster pressure & then crimp the small vacuum pipe coming off the vacuum pump to see if the vacuum readings improve. If it does you have something wrong on the turbo control side, if it doesn’t improve it is just the vacuum pump 😉
Many thanks, a very useful video. I've just watched a video regarding changing the exhaust camshaft and its above my skill level. Do you thinks its worth just changing the vacuum pump alone ( which i can do), or will the new pump fail quickly if i don't have the camshaft done too? Thank you again.
Just changing the vacuum pump alone will get the car back running good. And plan for the camshaft replacement down the line, the worst that can happen is the Dpf will block due to it being worn . Hopefully that helps Paul 🤞🤞🤞
Hi again. Yes it does help, so thank you very much. My last question is should the car start again after everything has been disconnected then reconnected without any specialist work? I remember issues in the past after changing a fuel filter on a diesel car. Again, many thanks.

Hello I have the 2016 cx5 ,I got the p258b error code and the yellow triangle light on dashboard ( no check engine light ) Car drives perfectly , what do you recommend me to do? Is it the vacuum pump?
@@kennedysgarage3281 Thankyou for the reply. Will changing the vacuum pump solve this issue? Or more work should be done? There are no really good mechanics in my area
If the vacuum pump if broken will it have an effect on proformances? I have a ish where at low reves it doesn't have the power it had previously looks like you point towards the exhaust pressure sensor aswell ?
No mate I had a chap come out with his snap on OBD and the The vacuum pump was read silly numbers in excess of 3k so that's the direction we've gone ... The turbo kicks in around 2/2.5 rmp
That’s a quality video! Do you think it’s reasonably safe to change vacuum pump now and then exhaust camshaft two month later? I have got p258b code on right now.
Yes, that would be fine. The exhaust camshaft being worn will only affect the fuel economy & the Dpf at some point. But that could be 000’s of kms down the line 😉👍👍👍
Great video! Quick question. I have a Mazda 6 Skyactive 2.2 diesel 2018 and have 2 codes. P0401 (carbon build up) and P258B. My main concern is that I cannot afford to buy a new vacuum pump. Is it possible to recondition the same vacuum, or what’s the cheapest pump I can get? How much would this cost.
I would suggest contacting you mazda dealer because some of them can be covered by warranty or a percentage of the part price. I have ever or heard of anyone reconditioning these pumps, but they are possibly able to be done 🤔🤔🤔
Great video 👍 I’ve got a 2014 cx5. It’s done 100k I replaced the turbo at 70k after actuator cap fell off, I about a month ago I done a deep clean on the intake and all the parts that get gunked up with carbon. The power double and it improved the car a lot, now a month later I’ve not this vacuum pump error code coming up. The Kpa is dropping slowly to about 12Kpa. You said this is related to cam shaft wear which is concerning me and since I’ve had the car I’ve always had one issue. I think the clutch could soon be on its way out, slight rust just above the windshield. Do I get rid of it and cut my losses or fix the parts in the near future? I will have to repair this vacuum issue before I sell it. What do you think???
You have the turbo done so I’d go a few pound more into it to get it right. But that just me. Replace the exhaust camshaft, vacuum pump & injector washers. Then replace oil pump timing chain & strainer @ a later stage an then you’ll have a great car 🤞🤞
Great video Peter..would you say there is a case to be made that if the vacuum pump need to be changed so too should the exhaust camshaft? Or vice Verda? Which leads me to my primary question..why does the exhaust cam shaft lobes wear so badly? Is it the “sticking” valves which then makes me ask..why do the valves stick so badly on the exhaust side? (..also no progress to report..just getting the Clubman off the ramp today 🫣so hopefully this week and have a 2016 1.6 CDTi Mereva sitting outside the door looking for some TLC..🤪)
Hey Damien, Look at the rockers I sent you. You will see all the lobes that wear have no roller bearing underneath, so steel on steel will wear. Then the exhaust valves only stick due to not being opened because of the worn camshaft. The sticking valves free out very fast once the new camshaft is filled. As for the vacuum pump failing, they say that is because of the metal from the camshaft 😱😱
Currently selling a 2015 Mazda 3 2.2D with 163000 miles (262000 km) and I have an unpleasant feeling that the vacuum pump is packing in. Ever wished you'd sold a car a year ago? 😅
I actually have a Topdon diagnostics machine and was able to replicate your results almost bang on. Had it booked in to get the work done in Belfast and lo and behold, someone bought it. I'm guilt free because I did tell them and took a few quid off to compensate. (Still glad It's not my problem) 😄.
I show the Mazda part number in my video, just take a screenshot. And the best place to get it is in your local Mazda dealership. They are easy enough to change 🙏🙏
Hi Peter, love your channel i watch nearly all your videos. I've started getting problems with my 2013 Mazda 6 2.2 Skyactiv. Error P253F Low Oil Pressure. Is this any easy fix? There's only 97k miles on the clock. I just had it serviced too so its ok with oil and that. Im based in Limerick btw
@@theartofflying3108 It can still be driven but the car will most likely be in limp home mode & possibly block the Dpf is driven anymore than a few days.

@@derekryan5760 yes, the camshaft is what caused the vacuum pump to fail. Replace the injector washers when in the too. They can contact me if they need any advice 👍
I got this P258B code at 78 000miles on mine. Its 2015 mazda. I clear it and it appears regulary every 12-14 engines warm-ups. I monitoring it with ForScan. Its strange I think if pump failed and not creating vacuum code would be permanent but after clearing it I can drive for days and after 12-14 engine worm-ups code appears and it appears when car is iddling after start up on warm engine. Any thoughts?
That is exactly what this video is for. Press the brake a few times before starting. Look at brake booster pressure sensor, it should be 100kpa start & within 30 seconds it should be under 100kpa. If that doesn’t happen you will need a vacuum pump & more than likely an exhaust camshaft 👍👍
why is your pump part number different? As long as I know part number for this vacuum pump is SH01-18-G00A. I never seen number SHY5-18-W00C. SH01 is engine code for skyactiv D 2.2. What SHY5 mean?
That I don’t know the answer to, but I do know that quite a few people have told me of price differences on different chassis number vehicles. I must do some research and see if I can find out the answer to that 😉👍👍
I bought a Vgate vLinker FS yesterday plugged it into my car and a laptop. Downloaded Forscan and was looking at this live data in 10 minutes. It cost me £27 on Amazon and £10 for the software. Give it a go it's great. Let's you code other features on the car as well not just fault diagnosis.
On the top of the ‘live data’ screen in the very middle, there is a little square icon. Swipe down on that and it opens up a little search bar on the top right hand side. I’ll do a ‘RUclips short’ on it Monday 😉
They can be expensive to own, the best and least expensive way to fix them is to do a cylinder head gasket and all related bits that fail. Around 5k but done once and for all 😬😬😬
