Before I ordered them, I showed them to my Lexus mechanic and he said they should work fine.
From the get-go about a year ago, that most irritating dash light starting coming on. You know, the one with the tire and the exclamation mark. I have a Blue Driver set up so I just erased the code. My wife complains next month, "That light is on again." I erased the code. Next month, same thing. Of course I am checking the tire pressures in all 5 tires and they are all ok. Light comes on, I erase, light comes on, I erase, etc.
I finally took the GX back to the tire dealer and he said I was gonna have to take my GX back to the Lexus dealer. Matter of fact, the tire dealer has a Lexus and he had to take his back to the Lexus dealer to get the TPMS system to work properly.
My friend is a Lexus mechanic and he said bring it to his house and he would reset all the codes. Dropped it off and he calls the next day and only 3 of the TPMS's will communicate with the GX's computer. So I have 2 that he can code and 3 he can't code.
We talked and I decided to replace all 5 TPMS's with Lexus OEM parts. $68 each (WOW!). It has been two months with no more orange lights on my "wife's" dash. I am hoping my TPMS problems are solved.
I know my results may be very different from any one else's, but I have decided all my TPMS purchases will be from Lexus or Toyota. The hassle was far too great for me (even though I used Denso)
The independent dealer had to manually enter the 4 codes to get it to initialize. These are the Rockauto Densos for the 2009 ES350. The tire light came on because of the 21psi grommet leak. I did inflate to 35psi, and pushed the underdash reset switch. The tire light did go out.
How long did it take for your Amazon Denso tire light to come back on?
Anywhere from between a couple of weeks to a month. Thinking about it, I'm not out of the woods yet
