Peugeot 308 Tire Pressure Sensor Fault
Summary of the thread
A 2023 Peugeot 308 hybrid displayed a tire pressure fault warning, suspected to be caused by a dead sensor battery. After manually confirming tire pressures were correct, it was suggested that the issue was likely due to a faulty TPMS sensor. A visit to the garage confirmed the sensor battery was depleted, and replacing it resolved the issue.

Yes, pressures are fine after checking all four tires, air valve and topping up air inflation. Was it definitely the sensor in your case?

Indeed, it was the sensor. After manually checking and confirming the tire pressures were correct, the workshop diagnosed a faulty TPMS sensor with a depleted battery. Given your symptoms and the age of your Peugeot, it's highly likely a sensor issue. I would suggest visiting a workshop to get it checked out properly. They can use a diagnostic tool to pinpoint the exact sensor causing the problem.

Thanks for confirming. Garage confirmed sensor battery empty and replaced it. Cost 280€. All sorted now.

That sounds familiar. I experienced something similar with my Opel Insignia a few years back. The TPMS (Tire Pressure Monitoring System) can be quite sensitive. When the sensor batteries weaken, they often trigger false alerts. Have you checked the tire pressures manually with a pressure gauge, just to rule out an actual leak or under-inflation? Sometimes, it's the simple things.
