That should still fall under emissions warranty, no? Sent from my SM-G960U using Tapatalk #3 · May 1, 2020 I posted the dealership repair manual for the 2016 Mazda 3 since I have one as well. I would try downloading and looking through it, it might be of help. I really haven't heard of this particular error before in the car, but I wish you luck. Please let us know if you do fix it what the solution ended up being. #4 · May 1, 2020 The car is in the dealership at Browning Mazda since 4/30. The tech just told me now that they can't figure out what's wrong so they called Mazda tech support for help. #5 · May 1, 2020 Oh wow, are they going to cover this under warranty? Or are you going to be coming out of pocket for the repairs? 0 Reply #6 · May 1, 2020 Don't know yet but I'm preparing for worst case scenario. Online they are selling the whole PCM for 700 plus installation. #7 · May 1, 2020 I would try to get some quotes from other Mazda dealerships around your area if you can, sometimes you can save money by doing that. 0 Reply #8 · May 5, 2020 Browning Mazda got some type of instruction to fix it but they couldn't. Now they are saying that engineers from Mazda are coming to fix it.... Huh? I had no idea that engineers from Mazda comes to dealership to fix cars . i hope the guy was not bullshitting. Well it has been 6 days including weekends that I'm without a car. #9 · May 5, 2020 From what I understand they do but it's very rare. Hope your car gets back on the road soon. 1 Reply #11 · May 6, 2020 Solution: Re-flash and Re-learn main engine computer and replace main fuse to engine. #12 · May 6, 2020 Glad you got it fixed! 1 Reply Insert Quotes Post Reply
