  1. Tire Pressure

    2019+ Mazda 3 Discussion
    Found this thread on Reddit, and went to check the TPMS readout in my 3, which had been sitting covered overnight. Sure enough... 43 or 44 PSI on all 4 tires. I had mentioned in another thread that my accelerator had a lot of "feedback"/vibration after the rocker arm recall that wasn't there...
  2. Exhaust Pressure Control Valve

    2014-2018 Diesel Engine
    Hi everyone, I have Mazda 3, 2016, CD105 diesel engine, and only 2 day after warranty expired I get check engine notification. I went to my dealership (all services are done by official Mazda dealership) and they check it I say it is error code: "P0476 Exhaust Pressure Control Valve...
  3. Brake Mean Effective Pressure: The Best Measurement for Comparing Engine Designs

    2019+ Mazda 3 Discussion
    Introduction Currently, Mazda produces three engines: the 2.0 L used in the Miata and the 2.5 L normally aspirated and turbocharged types. The SkyActive-X engine will not be part of this discussion as its exact specifications have not yet been announced. Some of our Forum members might be...
  4. AC pressure switch

    2004-2009 Mazda3 Discussion
    I have ordered at least 3 ac pressure switches that are located directly above where you fill the refrigerant in the low prrssure. Every switch I've ordered has been too thick of a threating to go back where the original switch was. The electrical connection part all matched. I would greatly...
  5. Tire Pressure Sensor TPMS Light indicator

    2014-2018 Mazda 3 Skyactiv How-To Guides
    Hey everyone So, it's been a while since I saw my TPMS indicator comes on. Actually since I bought the car in 2017 (new) I rarely see it lights. I think in all the time I have the car it came on maybe twice. This is regardless the fact that the tires off course has bee deflated several times...
  6. Hesitation and fuel pressure test

    2004-2009 Mazda3 Discussion
    My new-to me 04 Mazda 3 2.3 seems to have some issues acceleration. The car current has 122k miles on it. My previous 04 ran perfect till I sold it at 220k, so my standards are high. (I do realize that engines aren't consistently reliable when not treated well). I'm also getting some fairly...
  7. Pressure plate failing repeatedly 2016 2.5 6 speed

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    Hi all, Wondering if anyone else is experiencing this issue - at 12,500 miles the clutch pedal in my '16 2.5 6 speed was engaging at the very top of the pedal travel with no free play. Mazda replaced the pressure plate at no charge (even thought the wear item coverage for the warranty ended at...
  8. Continental DWS06 - Tire Pressure

    2014-2018 Mazda 3 Skyactiv Wheels and Tires
    Curious what other people run? Tire shop techs recommend the OEM PSI rating, it soakes up more bumps but feels less responsive. I asked them and they said they highly recommend not deviating because the center might wear faster due to overinflation. What do you guys think?
  9. Oil light? Low oil pressure in infotainment warnings?

    2014-2018 Mazda 3 Skyactiv Discussion
    This post has probably been done to death, but I've got a 2015 mazda 3 2.2 skyactiv-d. On Saturday afternoon the oil light came on and a warning about low oil pressure, checked the oil dip stick and it was raised and near the x. No worries I thought, I've known about this possibly happening...
  10. Automatic Transmission Oil Pressure Switch location on vehicle

    2010-2013 Mazda 3 & Skyactiv Discussion
    Hi I have a 2012 Skyactiv Mazda 3 that I am replacing this switch on. I have taken the transmission pan and what not off and I can't locate where this switch goes. If someone could either explain or show me a diagram it would be greatly appreciated. Thanks.
  11. High side A/C Pressure switch

    2004-2009 Mazda3 Discussion
    Hi everyone, owner of a 2008 Mazda 3i. 2 years ago I had the a/c compressor replaced, and worked fine for nearly 19 months. It now exhibits all symptoms associated with failing/ failed high pressure switch. My questions are: 1. Is there a way to test said switch 2. What's the difficulty in...
  12. Reading BluetoothTPMS (Tire pressure Monitoring) sensor data to your CMU Infotainment

    2014-2018 Mazda 3 Skyactiv Audio & Electronics
    It is possible to add live bluetooth based temperature/pressure sensors to your wheels and capture the data to your CMU/Infotainment via a bluetooth board with with USB CDC support that is plugged to the car's USB port. The only thing is missing is the UI. Though it is possible to integrate...
  13. Transmission pressure switch keeps leaking - common problem?

    2010-2013 Mazda 3 Engine and Performance
    I keep having a repeated issue with a transmission leak on my 2010 Mazda 3. From what I can tell of the maintenance records, it's always the transmission oil pressure switch that is found to be leaking. They replace it, tell me everything is good, a year later I bring my car back in for an oil...
  14. TIL: designated winter tires should be filled to 40.3 psi

    2014-2018 Mazda 3 Skyactiv Wheels and Tires
    I was going through the manual the other day and I glanced over what it seemed to recommend winter tires to be filled +4.3psi over the recommended 36 psi inflation for all seasons/summer radials The science behind it is that the air is less dense on colder weather thus requiring more air. :grin2:
  15. Plus sized wheel pressure

    Wheels / Tires
    hello, I just upgraded from the stock 16" on my 2016 3 hatch to 18"s and I was wondering if I am supposed to keep them at the same tire pressure I used on the old rims (34-36) or am I supposed to change it based on tire size? I have dunlop sp sport 5000 on them that are 215/45R18 89w. let me...
  16. Snow tire inflation pressure?

    2014-2018 Mazda 3 Skyactiv Discussion
    Anyone have a good explanation for increasing the pressure on snow tires? The following is from the Mazda owners manual: Inflate snow tires 30 kPa (0.3 kgf/cm 2 , 4.3 psi) more than recommended on the tire pressure label (driver's door frame), but never more than the maximum cold-tire pressure...
  17. Water Temp/Oil Pressure gauge??

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    So I recently purchased a 2017 Mazda 3, which I'm in love with. However, the one thing that bothers me is not being able to see water temperature and oil pressure. I've noticed there aren't any gauge pods out for the Gen3 right now, so a custom gauge pod would probably have to be fabbed up (not...
  18. Check Engine - P061B Torque Calc + P2229 Baro Pressure

    2010-2013 Mazda 3 Engine and Performance
    Hey guys, First time posting here. Looking for some help with my friends 2013 Mazda 3 5-Spd Sedan. She was driving home from work today when the money light came on and she said her car felt sluggish and hesitant afterwards. Came by with my scan tool and pulled up these codes which I haven't...
  19. High pressure oil lines

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I like K&N oil filters. But the Mazda dealership wrench-man said the high-compression Mazda-3 (2.5L) has high pressure oil lines. So I should stick with the Mazda oil filter. Comments ?
  20. What tyre pressure for aftermarket 18inch rims?

    2014-2018 Mazda 3 Skyactiv Wheels and Tires
    Hi everyone, I recently upsized my 16 inch rims to 18 inch ones and the lads recommended 240 kpa for the new tyre pressure(225/40). The original factory recommended tyre pressure for the 205/60 R16 wheels was 250 kpa. Any thoughts and advice as to the correct pressure to use?
