BMAX Tire Pressure Warning

Hi, I have a 2015 Ford BMAX with a diesel engine and I'm getting a tire pressure warning. The car only has 29809 km on it. The error message 'Tire pressure too low' keeps popping up on the speedometer, and I had a look with an OBD scanner which confirms an error is stored related to the TPMS. I've checked the tire pressures manually, and they're all fine. I'm suspecting a sensor battery might be empty. Anyone experienced this?

Could be a faulty sensor. But are you sure the pressures are correct? Sometimes a small difference can trigger the warning. I had a similar issue on my old Mondeo, and it turned out one tire was losing pressure very slowly due to a nail. Double-check all your tires carefully before assuming it's the sensor.

Thanks for the reply. I've checked them twice now with a digital gauge and they are all spot on. Is there a way to confirm it's the sensor without just replacing them?

Okay, if you're certain about the pressures, then it's highly likely to be a sensor issue. Unfortunately, without specialized tools, it's difficult to pinpoint which sensor is failing. I'd recommend taking it to a workshop; they can diagnose it properly. I ended up replacing all of mine as a precaution on my previous car.

Thanks for the advice. I took it to a local garage, and they confirmed it was a faulty sensor with a dead battery. Ended up costing me 280€ to replace. Appreciate the help!
