Low Tire Pressure Warning Light question - Toyota Nation Forum : Toyota Car and Truck Forums

Joe B · 06-30-2005, 09:18 AM

Mine came on yesterday.
The pasenger side front tire had 2olbs of air.
Must have a slow leak.
I didn't know the '05 Corolla has a low tire pressure monitor.
My question.

I don't see any monitors on the rims.
How does the system monitor air pressure?

If anyone is interested in the answer to my question I got an answer.

Uses the ABS sensors to monitor air pressure. Since a tire low on air has a different circumference than one filled with the proper air pressure. You will get a different number of revolutions at speed from one side to another.

Check your manual for an idiot light that will come on when pressure is low.
I didn't know the Corolla had thai feature.
It's pretty kewl!

I'd hate to reply to this so late, but could you help me with mine, too? Do you have any ideas? I posted about it here:
