I got the low tire pressure on the info screen, Cheked pressure put air in tires. Now it won't go away, What do I do?

 

You might still be under-pressure and/or have a leak. What air pressure did you fill them to? Always check the pressure when the tires are cold, because this is the reading that should match up with the recommendations that are listed on the door jam.

 

proper tire pressure procedure is to use manafacturer specs when the tires are cold not sure if you checked them if they were warm

 

I've been through this twice now, with some cooler weather, and the trick is that you have to overinflate them a little to get the monitors to reset.

Just run the tires up to 40 or so, turn on the ignition so you can see the display, and when the warning is off, bleed off the excess to get back to the right pressure.

 

if your tire pressure is right and its still turning on, make sure your tire pressure monitoring is on Main not 2nd.

 

mine went off last week--all 4 tires were low. After inflation, the warning went a way about 10 sec after re-ignition. If all the tires are indeed properly inflated, you may need to re-initialize the sensors (instruction in the manual).

 

A friend of mine had the same problem with his Honda. It ended up being the spare tire that was low on air. Does Lexus put a sensor in the spare?

 

What kind of Honda ??? I'm not familiar w/any Honda/Acura that has a TPMS sensor in the spare - almost all of them have the silly lil' compact donut. I know my '06 IS350 has the compact donut and it doesn't have the sensor . . .

 

Went to the dealer today, pressure was off but they said they had to reset the computer, whatever it works thats all i care about.
