Guys,
I need your help! The low tire pressure light on my 2007 RX 350 was on during highway driving yesterday. I checked the tires right after that and found one of the aluminum tire valve caps was missing. All other 3 caps were very lose as well. I did the oil change the day before yesterday and I saw them added more air into the tires, so I believe they didn't tighten the valve caps :(
My question is - could the low tire pressure light be triggered by the missing valve cap?
BTW, I checked the tire pressure of all 5 tires including the spare tire and all of them were above 30 psi.
Also, I followed this thread and deflated all the tires including the spare. Did the reset and did the proper inflation of the tires to >30 psi. But the light is still on. When I turn on the engine, the light is just flashing for about 60 times and then keeps on.
Could this be the problem with sensors? Should I take the car to the dealer now? Any input is welcome, thanks a lot!
All the best,
Tom
