On my dash display under the tire pressure (PSI) display it use to show the air pressure in each tire and the spare tire. Now it does not show the air pressure, only shows blank dotted lines! How do I make it show the air pressure in each tire?
Thanks

 

Did you rotate tires or adjust tire pressure recently. Any battery issues? You may have incorrectly reset the TPMS. Please consult your owner’s manual for detailed instructions and troubleshooting - pages 761-765.

 

I found my problem - unfavorable radio wave conditions! Thanks for your help!

 

I know this is old, but I just recently replaced the TPMS and am having the same issue. It works, but doesn't show the numbers. Tire pressure went low and the light came on, but doesn't show the numbers. Air was added to the Tire and the sensor light came off.

 

Most major tire dealers are equipped with the knowledge and electronic tools to evaluate your TPMS. Some will help you for a nominal charge or maybe no charge. Costco, Walmart and Discount Tire come to mind. A Lexus dealer would probably be the most expensive.

 

Went to two Discount tire locations, and Walmart, and still cannot find out what's wrong. From researching, my guess is narrowing down to either one sensor goes bad or breaks during install, and this is the cause or you have to buy ALL OEM. Not sure if anyone can confirm if this is a possibility.

 

Did you have all 4 new sensors installed, and if so, what was the reason? I haven't had this issue but would venture to say that at least one may be bad or perhaps not registered to the vehicle. Another possibility could be a faulty TPMS monitor/receiver module.

 

I had bought OEM LC500 wheels and tried to get the sensors set by Discount tire and Toyota, but still did not work. I bought a new set of 4, and got it installed by Discount tire. The tire(tpms) light went off, but the psi tire pressure numbers do not show(only display dashes). I drove it for a couple days and still did not display any numbers. The tire light came on and said I had low air. I went back to Discount tire and they aired up the tire, and the light came off right away. The air was leaking from the tire because they installed the seal wrong. They reprogrammed the sensors and still the same thing. No numbers would display, but the sensors work.

Is registering the TPMS to the vehicle the same as programming it to the vehicle?

 

It’s hard to say with the information you provided. My guess is that your sensors are not the correct part for your car.

 

What about the spare sensor? If the computer looks for 5 working sensors and one is dead......not sure, but worth considering.

 

It could be the spare. When I had the OEM tires on, they were all working fine, but that was a year ago.

 

How do I find this? Thank you.

 

Please rephrase your question. THIS is too vague.

 

I am trying to find the PSI tire pressure setting so I can view the PSI on the dashboard screen. I am sorry not sure how to word it. I saw where the settings are but there must be more pages/screenshots. This screen thank you so much

 

There's a button on steering wheel "Display" will change that screen every time you press it. If this never appears, it's likely at least one of the tire sensors is dead. One dead = no display.
