2014 Diesel Mazda Axela Experiences Engine Issues: Could it Be a Throttle Valve Fault?

Jerking on acceleration

Poor fuel economy

Hey all, I've got a bit of a puzzle with my 2014 Diesel Mazda Axela that's run a good 238,026 KM so far. She's been acting real wonky lately, with her engine light staying on, engine cutting out unusually, feeling like she's losing power, running unevenly, jerking when stepping on the gas, and chugging a whole lot more fuel than she should. After a lousy experience last time at the mechanic, I'm thinking this could be tied to a throttle valve fault? Anyone had similar episodes with their vehicles? How did your mechanics deal with it? Appreciate your insights!

Hey, that definitely does sound like a pickle you're in. I had a similar issue with my 2017 Mazda CX-5, same diesel beast like yours but on a fancy SUV. Turned out, the whole mess was because of a problematic accelerator pedal module, not the throttle valve really. The engine light was the initial warning sign, with the power loss and the erratic driving pattern following suit. When I took my car to the local garage, the mechanic ran some diagnostics first to get a proper sense of the problem. He found out the error codes relating to the accelerator pedal module were showing up. So, they replaced that faulty pedal module. Don't want to scare you, but it was a tad bit serious as this module basically translates your foot's commands into signals for your engine. Screwed that up, and you're in for a wild ride. She's been running as smooth as silk since then, so your Axela is likely in a need for a similar fix. Good luck!

Hey there, thanks for sharing your experience. Sounds like you hit quite the bump but I'm glad things got sorted out for your CX-5. I reckon we could be battling the same demon here with my Axela. Just out of curiosity, how hard did replacing that accelerator pedal module hit your pocket? Also, since you got it fixed, did any other gremlins start to pop their heads? Hope she's been treating you right! Cheers!

Hey, getting that accelerator pedal module sorted didn't exactly come cheap, but it was worth every penny. Ended up shelling out about 205.00 € to wave goodbye to that devil. And about other problems creeping up, I've been fortunate so far. She's been purring like a kitten without any new issues rearing their ugly heads. Especially that throttle valve issue we were discussing earlier hasn't resurfaced since the mechanic worked his magic. Plus, the fuel guzzling has noticeable calmed down. So yeah, fix that pedal module and your Axela should be good to go! Fingers crossed for you!

Thanks heaps for easing my concerns! Very helpful to have a ballpark figure so I know what I'm potentially looking at. Tremendously relieved to hear nothing's haunted your CX-5 after the fix. Fingers crossed my feisty Axela follows suit after we tackle this pedal module ghost. I'll definitely take your advice on board, and hopefully I'll be ripping the roads again with my Axela in no time. You've been a right legend! Cheers for the assist.
