Tire Pressure Light is on even though the tires don't need air.
My tire pressure warning light has come on several times on my 2004 RAV4. I've had a mechanic reset it before and check the tire pressure. The tires are fine, but the light ends up coming on again. Could this be an issue with the electrical wiring? I just care because I would like the warning light to actually provide a warning if the tires are low.
