Celica Tire Pressure Warning

Hey, I'm getting a weird tire pressure warning on my 2004 Toyota Celica with a gasoline engine. It's got about 21833 km on it. The light's on, and the speedometer shows an error, but I've checked all the tires, and they're properly inflated. Could it be a sensor?

I had something similar happen with my Opel Astra. Tire pressure light was on even after I checked the pressure. Did you check the spare tire's pressure? My spare had a faulty sensor that triggered the warning.

Thanks! I appreciate the spare tire suggestion. But my Celica doesn't have a sensor in the spare. Any other ideas what could cause the error?

Gotcha. If your spare doesn't have a sensor, it's probably one of the main tire sensors failing. Usually, that means the sensor battery is dead. I'd take it to a shop to diagnose and replace the bad sensor. That's probably the quickest fix.

Thanks for the advice! I took it to a shop, and you were right, it was a dead sensor battery in one of the tires. Replaced the sensor, and the error's gone. Cost me 280€, but it's fixed!
