The TPMS units are actually manufactured by Pacific Industrial under contract with Denso Corporation and Denso markets them themselves and sells them to numerous carmakers who typically repackage them in their own branded packaging, such as the red and white Toyota scripted boxes we often see (image below).
Click the above link to see all the automobile related customers Pacific Industrial makes them for, which you will see also includes Denso - so technically it's not a rebrand when Denso markets and sells them to places like RockAuto.

The picture is a Pacific Sensor in a Toyota box. I honestly am not sure what your point is. Dill also repackages Pacific sensors also. I would recommend that the replacements used are Pacific, Dill or Denso but they are all Pacific sensors in a different box. Wouldn’t pay the extra for a Toyota/ Lexus box that’s for sure

I wouldn't be interested in buying a repackaged Pacific TPMS in a Dill box. Pacific Industrial does not manufacture Dill TPMS sensors and of course Dill does not manufacture Pacific TPMS sensors.
Dill Air Control Products designs and manufactures their own line of TPMS sensors but the company does offer some types of TPMS sensors made in France, Germany and other countries...and Dill offers some TPMS sensors made by Pacific Industrial.
I personally would only install the correct TPMS sensors for the car made by Pacific Industries, and if they are purchased in sealed Toyota packaging that's all the better because it assures they are genuine and will perform as the original equipment TPMS sensors did when the car was new.
I wouldn't be interested in buying Dunkin donuts in a Krispy-Kreme box, or Heinz ketchup in a mustard bottle or Mobil 1 motor oil in a STP bottle. I don't want to buy a Coca-Cola in a milk carton and neither do I want to buy a Pacific TPMS sensor in a Dill box.

If his scan tool is showing locations from the ECU. Never used an autel but sounded like that’s what he meant
The Autel tool does read sensors and will do the position relearn through the OBD connector. However I found that my tool is transposing the two rear sensor positions. After scanning all sensors in order, and programing to the ECU, Techstream shows the right rear sensor in the left rear position. So I scanned the rear wheels in a different order, and sure enough, they showed up in Techstream in the opposite positions. Tool must be defective.
I am also wondering if I got the wrong sensors. I got them from eBay (part #42607-06020) which said they match. The site showed alternative part numbers, but when I look at Lexus online parts for this car, they only show #42607-30060. And that was one of the alternative part numbers on the bay listing. In Techstream, everything is in the right position and showing pressures, etc. But still have dashes showing on the instrument panel. I sure wish we could get some temperatures above 40 degrees, to see if this temperature related.

Not trying to keep going back and fourth but I can tell you for sure that if you buy a Dill sensor for our vehicle you are going to find a Pacific stamped sensors inside the box. Just like the Denso one. I’ve bought hundreds and the Dill 1218 is a Pacific sensor.

Curious. What order where you scanning them in and what order worked.
is the actual tire light off? If so and you replaced them all I’m pretty sure you got the wrong sensor

Yes, I know and agree with you - as I previously said; "Dill Air Control Products designs and manufactures their own line of TPMS sensors but the company does offer some types of TPMS sensors made in France, Germany and other countries...and Dill offers some TPMS sensors made by Pacific Industrial." - as exampled by their Dill #1218.
It's like buying a Dell computer from Hewlett-Packard that has it packaged and labeled in a Hewlett-Packard box. That's okay as long what you expect to buy is the genuine article.
For anyone that wants to know how old their Pacific Industrial made TPMS sensor batteries are.
If the TPMS sensors were made by Pacific industrial (for Denso or repackaged and offered by Dill, provided by Toyota/Lexus or Discount Tire, etc.):
The above TPMS sensor has a date code of '13C19' which means this particular TPMS was built in year 13 (= 2013), of month C (= December), on day 19 (=19th).
[This particular TPMS was manufactured on December 19, 2013 which includes its nonreplaceable integral battery]

Note: The following post is from an old thread (posted for the information that may be helpful to others dealing with dashes - - instead of tire psi):

@lexo98 - Vehicles' various ECUs can become energized in a staggered manner due to how the car's CAN (Controller Area Network) operates in a particular vehicle. The Controller Area Network is a communication system that allows electronic control units (ECUs) to communicate with each other. The TPMS sensors themselves were most likely asleep and could have been slow to wake up, thus throwing all dashes (- - ).

As you probably already know TPMS sensors are triggered to transmit their signal data by emitting a 125 kHz radio frequency signal in close proximity to the TPMS sensor by a TPMS programming tool. But the TPMS sensors can also be awakened by using non-contact magnetic force from a relatively strong magnet - and of course a significant air pressure change should also awake them.
Not wanting to alter the tire air pressure to awake the TPMS sensors - it would be an interesting test case for someone with a vehicle that always seems to display dashes (- -) instead of tire psi to use a donut or U-shaped magnet (see image below of a donut magnet dedicated for use with TPMS sensors) before starting the vehicle to see if the magnetic force kick-starts the TPMS sensors to fully wake up for their 315MHz RF signal transmissions to display tire air pressures.

Nothing to do with the sleep mode. They were transmitting just fine, but they are old and the batteries are weak. If I deflate a tire the warning light still comes on.

So, you have new TPMS sensors but you haven't replaced them yet?
This is for anyone that wants to know how old their TPMS sensors are (including the batteries) that were made by Pacific Industrial:
If the TPMS sensors were made by Pacific industrial (for Denso or repackaged and offered by Dill, or provided by Discount Tire, or originally factory installed by Toyota/Lexus:
The above Pacific Industrial TPMS sensor has a date code of '13C19' which means this particular TPMS was built in year 13 (= 2013), of month C (= December), on day 19 (=19th).
[This particular TPMS was manufactured on December 19, 2013 which includes its nonreplaceable integral battery]
When getting new tires or anytime a tire is removed from its wheel it is recommended you take a closeup, in-focus picture of the TPMS sensor so you can read the date code and you'll know for sure its manufactured date and how old the TPMS sensors in your wheels really are, without guessing.
Any tire shop, including Discount Tire, will accommodate a customer's request to snap a picture of the TPMS sensor. They can just bring the TPMS sensor to you and put it in your hand...
