Honda Avancier Tire Sensor Woes: Real Fix or False Alarm?

Hey there! I have some experience with cars and had a similar issue with my 2004 Honda Accord (I also own a Civic). The exact same thing happened, persistent low tire pressure warnings despite normal tire pressure. Turned out the TPMS sensor batteries were dead. Took it to my regular mechanic, who replaced the sensors. The whole thing cost me around 280€ but totally worth it for peace of mind. Quick question though, are you getting warnings for all tires or just specific ones? This detail would help figure out if you're dealing with one faulty sensor or if they all need replacement. Also, how long have you had these warnings popping up?

Thanks for sharing your experience! I'm getting warnings for the rear right tire only, so hopefully it's just one sensor acting up. My Avancier is at 58507 KM and had its last service about 3 months ago, but they didn't mention anything about the TPMS then. The warning started flashing about 2 weeks ago. Good to know about the sensor battery replacement, definitely sounds more reasonable than what I was worried it might cost. Did your mechanic have to program the new sensors, or was it just a straightforward swap?

Since I shared my Accord experience earlier, let me follow up on that! Yeah, in my case when I had the sensor replaced, they did have to program it. It wasn't just a simple plug-and-play job. The programming was actually included in the price I mentioned before. Funny enough, mine also started with just one tire (but it was the front left). What's interesting is that when I initially took it in, my mechanic said that when one sensor starts failing, the others usually aren't far behind since they're all the same age. I didn't believe him at first, but guess what? About 4 months later, another sensor started acting up! Since your car's only showing issues with one sensor and it's relatively recent, you might get lucky with just needing that single replacement. But honestly, given your mileage, it might be worth asking about the condition of the other sensors while you're at it. Could save you another trip to the shop down the line. One tip from my experience, make sure they check the valve stems when they do the sensor replacement. Mine were a bit corroded, and replacing those at the same time saved me future headaches.

Thanks so much for all that detailed info, super helpful! That's a really good point about checking the other sensors while I'm at it. Might as well have them take a look since I'll be there anyway. Definitely don't want to deal with this same headache in a few months if another one fails! And I wouldn't have thought about the valve stems, so I'll make sure to mention that too. I'll give my mechanic a call tomorrow and set up an appointment. At least now I know what to expect and won't be shocked when they mention programming costs. It's way better than I was imagining, I was worried it might be something wrong with the whole system! Really appreciate you sharing your experience with this. I'll probably just bite the bullet and have them check all the sensors while they're at it. Better safe than sorry, right?
