Peugeot 406 tire pressure error

Hey, I've got a 2003 Peugeot 406 with a gasoline engine and I'm running into a weird issue. The display keeps showing a 'tire pressure too low' error, and the speedometer has a constant error message about it. I checked the error memory, and there's definitely a fault stored related to tire pressure. All tires are properly inflated. Anyone seen this before? I'm suspecting a faulty sensor, maybe just a dead battery after 254439 km.

Hmm, sounds familiar. I had something similar happen with my old Opel Astra. Kept getting low tire warnings even though the pressure was fine. Did you try resetting the TPMS? Sometimes that helps, but in my case, it was a temporary fix at best.

Yeah, I tried resetting it a couple of times, but the error comes back almost immediately. Did yours eventually turn out to be a sensor issue then?

Yup, eventually it was the sensor. The battery probably died. Honestly, after the reset didn't work, I just took it to a workshop. They confirmed it pretty quickly. It's probably worth getting it checked out properly rather than chasing ghosts.

Thanks for the advice. Took it to the shop, and you were spot on – dead sensor battery. New sensor fitted, cost me around 280€, and the error is gone. Appreciate the help!
