That is totally clogged! You can’t see daylight.Effectively it cannot register manifold pressure changes when your pistons move.just looked to see what that cable is and sending you photos.From what I can tell the cable on my car runs to the alternator.I don’t know what’s happening as you must have a cable to your alternater.
Yeah it was really bad. It took quite a bit of time to clean it. Your'e right, a needle worked great. I ised a toothbrush as well but it was well solid. There's no possible way that could have been functioning correctly, or at all! I probably could have done a better job of cleaning it, but at least the sensor part is clear. I took the car for another spin this morning and plugged in the ODB reader. No errors or pending errors at the moment. I won't know for sure for at least a few more days.
Regarding the supposed cut cable, my alternator seems to be connectod alright. I will need to check over it again. I'm sure if it was a major issue, something would be noticeable. The only issue I have with the car now is that there is a clear juderring/vibration feeling on the steering wheel at high speeds - over 65 mph usually. I thought maybe it was the wheel balance but not so. I've had this checked. I have absolutely no idea what is causing this, but it is very notiecable. I will worry about this issue when I get the EGR/vacuum faults resolved.
I can send you a brilliant link for your engine where they do a 26 minute video cleaning the EGR system out of a CX5.It looks complicated if your not a mechanic and it won’t be cheap.How to Clean EGR System Removing Carbon MAZDA CX-5 2.2D 2014~ SH-VPTS FW6A-EL AWD Part 1.
Wow, how in heck did you find that? That is really helpful. If the MAP/MAF sensor cleaning doesn't resolve, I will definitely look into this. I had the engine carbon cleaned as well using a hydrogen cleaner or something. I am hoping this will make a difference. I will definitely watch this. Very useful!
Well pleased for you Viper and hopefully your sorted without using using a sledge hammer to crack a walnut.Just put the above words into google and the video comes up.Its a workshop in the Far East and they do a total strip down and remove the EGR cooler etc which you don’t have to do.However there is a 10 black bracket you need to to remove to get EGR off.😃
Hahah I've felt like taking a sledge hammer to the engine a few times, believe me! Not because it has been unreliable or anything, but just because of the annoying error codes that multiple garage visits have been unable to resolve.
I have read the vacuum pump may be a Mazda recall.See how you get on.
Yes I read that too somewhere. I did an online check with some Mazda recall checker (sorry, can't rememeber where I found it) and it said no recalls were due for mine. I may as well call them just to double check that this is correct. The only other post I've come across about the P258B fault was where a mechanic mentioned he had replaced loads of vacuum pumps due to this fault. If the red warning triangle comes up again, I may have to consider swapping it out. It looks more challenging than replacing the EGR valve so I might take it to a garage for this if needed.
How are you getting on your with Mazda Jay? I hope yo've got to the bottom of your issues. Many thanks again! You've been a great help
