I remember the Sienna forum moderator would recommend kits like this one, which used to include a mix of 433 and 315, as well as metal and rubber stems, (also used to be cheaper too). Now they appear to sell the dual frequency type. Here's a kit. They would typically go on sale when Amazon has their sales. I know Porsche uses metal stems so I selected one of those. Also note the Autel Programmer probably only works to program Autel sensors:

EDIT- If you look carefully through the Autel kit I linked you may find (like I did just now) that Porsche is mentioned there as Automatically Relearn. If the error doesn't to away in the first say 5 - 10 minutes after turning the car on immediately suspect bad/incorrect/defective sensor(s). These systems tend to wake the sensors on start-up, so results should be very quick as I noted once I drove a little...

 

Ok to put closure on my issue, I did get the wrong TPMS with 433mhz. It should have really been 315mhz. I ordered and got those low priced China TPMS 315mhz, installed them...did a reset and they were recognized and now working perfectly.

So its was really the frequency. The ebay seller said they pre-programmed them with 433mhz while my Pan 970.1 is 315mhz.

Thanks everyone for your inputs and insights!
