Lexus ES tire pressure sensor issue

I haven't seen that exact issue, but those sensors use batteries. Is it one specific tire, or random? Have you checked the tire pressure with a manual gauge to rule out a flat?

The error is consistent across all tires. I used a gauge and the pressure is correct. Could a faulty receiver unit cause this, or is battery failure still most likely?

A faulty receiver is possible, but less common when all sensors are affected. Since the pressure is correct and the error is on all tires, sensor batteries are the prime suspect. I'd suggest a workshop visit to confirm, but prepare for sensor replacement.

I visited a service center, and the tire pressure sensors needed replacement due to depleted batteries. The total repair cost was 280€.
