Supra Tire Pressure and ABS Issues

Hey, my 2023 Toyota Supra IV with a gasoline engine is acting up. Just passed 53211 km and the low tire pressure light came on. I checked the pressure and inflated the tires, but the light's still on and now the ABS light is on too! Plus, the steering wheel is vibrating, and it's hard to steer, like the power steering failed! I checked the tires for punctures but didn't see anything. Any ideas?

Interesting. I had something similar happen in my 2018 Volvo XC60: low tire pressure warnings, ABS light, and steering issues. Did you check the tire sensor itself, not just the tire pressure?

Tire sensor? How do I check that? I know where it is, but is there a way to see if it's working without an expensive tool?

On my Volvo, it was a defective valve stem on one of the tires, causing a slow leak and messing with the tire sensor readings. The system is sensitive. I'd suggest a workshop. They found it fast and confirmed it. It's worth checking if it's similar. Seems like a defect triggering all the errors.

Turns out, you were right! I took it to the shop this morning, and it was a faulty valve in the tire causing a slow leak. A new valve and sensor cost 280€, and all the warnings are gone. Steering is back to normal. Thanks for the help!
