I have a 2011 Accent and the tire pressure light came on, not the TMPS light. I serviced all 4 tires to 32 psi and drove 50 mph for about 22 miles. The light never went out. I deflated all 4 tires to below 20 psi. Then serviced to 32 psi and drove again. The light still does not go out.
Is there a way to reset the tpms to relearn the sensors? I know on some makes/models there is a reset button under the dash. I have looked and don't see one on this car. Maybe I just missed it. Is there a reset button?
