Also if you had a bad one in there and the tpms reset button kept getting pushed Toyota/ lexus go into a lock out mode. Not all do it but it happens and if you don’t have a tool to take the ECU out of closed loop the light will never turn off. Even some skilled techs don’t know what to do and tell you to just drive.

Last night I used the AUTEL tool to scan all the sensors and they checked out. Two of the tires had a 30 PSI so I inflated them this morning. Tonight I will hook up the tool and do a ODB relearn and go for a drive- hopefully this fixes it.

I’ve never used an Autel but with the tools I use immediately after programming the ECU you need to rescan each sensor so it sends a signal. LF RF RR LR SPARE if you don’t have a spare skip that. Most of the time a drive is not required.

Update- light started flashing again. Used the Autel tool and it looks like my passenger side front is now going bad. At this point, I've decided to replace them all.

Is it ok to use Shrader sensors? They are $21 on Rockauto- or should I use Denso?

Two TMPSs of my 2012 ES350 back tires were bad detected by both Discounted Tires and Costco Tires. I went three stores today. Discounted tires' quote said Five Dill 7007HP 71 315 Clamp for $225 ($415/sensor), labor for $55, backup tire for $71 (my old one from factory, never used in past 12 years), certificate for tire $14.1, Total $405. Lexus dealer, ~450 for four sensors, labor around $350 (saying installation takes 2~3 hours, Fxxk them), and programming .... Costco: five 7007HP RS 315MHZ METAL for $232.5, free installation and programming. Deal at Costco at last. The job was done within 25 minutes! One can DIY, however, i am not confident with the relearning (programming), even with those pre-programmed sensors (~$65 for five top-rated ones).
