I had a "low pressure" warning light come on for the passenger side front tire. Checked the pressure and it was 38lbs. I brought it up to 40lbs. which is the same as the other tires and consistent with the recommendations on the drivers door instructions. Have now driven for a couple of days and the light is still on even though the pressure is holding at 40lbs. Is this just a "wait it out" scenario for the reset of the warning light?
