Hello all, I haven't posted on here for a long time but I need some help so I come to the experts!

I had 4 new tires installed a couple of days ago on my 2015 460L with 70k miles at Discount tire. I also had them replace all 5 TPMS sensors with new OEM Toyota sensors which I got off Ebay. Now the TPMS screen on the dash is blank (just dash lines) and the TPMS warning lite is flashing all the time. I tried resetting the system per the manual with no luck, the warning lite just flashes all the time and doesn't change when I hold the button under the dash. Any thoughts on a fix? The TPMS was working fine before the tire change. Thanks!

 

Any time a sensor is replaced the unique ID must be uploaded to the ECU. Not sure if the tire shop did that for you but it is mandatory. Pushing the reset button when the IDs haven’t been uploaded can cause the system to go in a lockdown mode.

Also, the sensor for that vehicle is specific. Lots of problems with EBay sensors.

 

Tell us the Part# of the new sensors?

 

I just went through this on my wife's Acura MDX and turns out that the sensors were not Honda, I have to use a different type of calibration machine cause the part is not OEM even though it said Honda on the label part number was not in the database. In other words, a knock off.

 

Thank you all for the info, I am going to check P/N's again, I may have ordered the wrong sensors. The tech at Discount Tire did register the sensors but the aren't connecting with the car. P/N of new sensors is 42607-33021 PMV-107J 315 MHZ.

 

Not sure what is the difference but according to Lexus P/N for the sensor is 42607-30060 (https://parts.lexus.com/p/Lexus_2015...260730060.html).

 

Your parts are for 2007-2012 LS460s. The 2013 and newer LS460s require a different part#. The OEM part for 2013 LS460s and newer is: Denso 550-0105.

 

Yesterday, I had all TPMS sensors replaced on my '10 460L, including the spare at Discount Tire, after the warning light started flashing to have TPMS checked by dealer. DT said two sensors were bad but I decided to replace all of them. No problems.
