Seeking Advice on Troubleshooting Tire Pressure Sensor Issue in 2018 Mazda CX3

Tire pressure to low

Hey everyone, I'm dealing with a bit of a puzzling issue on my 2018 Mazda CX3 with a gas engine. Lately, it's been showing low tire pressure - even though I've checked and the pressure seems fine. Thinking it might be a glitch with the tire pressure sensor, but I'm not 100% sure. Anyone run into something similar or have ideas on how to troubleshoot? If you've had this problem and got it resolved in the workshop, could you share your experience? Really appreciate any tips or suggestions.

Hey there! Not long ago, I had the same issue with my 2017 Mazda CX5 - pretty similar model to yours. I'm not a car whiz but I have some experience with it. Turns out, it was a sensor battery problem. Took it down to my local workshop - those guys know their way around Mazdas - and they figured it out quick. Swapped out the sensor battery and things went right back to normal. Cost about 280€ all up, a bit pricey, but it did the trick. Sounds like your problem might be the same? Double check with your workshop. Also, it'd help to know a bit more about your car - any other symptoms or recent work done? Hope this helps!

Thanks for your advice! Appreciate you taking the time to share your experience. Sensor battery problem, huh? Never would've thought of that. I actually just had my Mazda serviced, not too long ago. It's currently sitting at around 37,085 km mileage, runs like a charm - this issue aside of course, lol. There hasn't been any other work done or any other symptoms. I'm guessing my ride’s problem is likely the same as yours. I've got a trustworthy workshop nearby, they know my 'lil Mazda inside out. I'll run this problem by them, let's see if it's the sensor battery. Fingers crossed it doesn't cost an arm and a leg! Thanks again!

Hey, no problem at all! I’m glad I could help you out. Your mileage is quite low, which is good, but that sensor battery doesn't really care about usage, they tend to have a lifespan of about 6-10 years typically. So, its age might be the culprit. If the shop you’re talking about is as good as you say, they'll probably do a great job diagnosing it, and worst case if it is the sensor battery replacing that isn't the end of the world. And hey, while it can be a bit of a hit to the wallet, it sure beats driving around guessing what the tire pressure is, right? Anyway, good luck with it, hope it all goes smooth. Let us know how it turns out, always good to get more data points on these kinds of issues. Safe driving!

Cheers for the reassurance! Yeah, the sensor's age could definitely be a factor. I got the car used and never really thought about the sensor battery before this. It's good to know this isn't a doom-and-gloom kind of problem. I agree, the peace of mind will definitely be worth the hit to my wallet, haha. I'll update once I've had it checked out - might help someone else in the future. Thanks again for all your advice, really appreciate it. Safe driving to you too!
