S90 tire pressure sensor fault

I'm experiencing a tire pressure sensor fault with my 2022 Volvo S90 diesel. Mileage is at 145712 km. The system indicates 'Tire pressure too low' despite correct inflation. This is accompanied by an error message displayed in the speedometer, and an error is also stored in the error memory. I suspect a sensor battery issue. Has anyone encountered this?

Summary of the thread

A 2022 Volvo S90 diesel is experiencing a tire pressure sensor fault, displaying a 'Tire pressure too low' warning despite correct tire inflation. The issue is suspected to be due to a sensor battery problem. A similar case confirmed that a failing sensor was the cause, and a workshop visit for sensor replacement and programming resolved the issue.

Did this summary help you solve your problem?

I have an S90 as well, and I had a similar issue. Did you check the tire pressure manually to rule out an actual low tire situation before assuming it's a sensor malfunction?

Yes, I performed a manual tire check and confirmed the pressure is within the recommended range. All tires are properly inflated. That's why I'm leaning towards a sensor problem. Was your issue also triggered by correctly inflated tires?

Affirmative, my S90 exhibited the same behavior – correct tire pressure but persistent TPMS warnings. It turned out to be a failing sensor. I recommend a visit to a reputable workshop for diagnosis and potential sensor replacement. The battery life on those sensors isn't infinite.

Thank you for confirming my suspicions. I appreciate the insight. I took it to the workshop as suggested, and it turned out that the tire pressure sensor battery was indeed empty. The repair cost was 280€, including sensor replacement and programming.
