TPMS conundrum

Hello Tundramen,
Trying to help my Dad with his ongoing TPMS problem.

2006 Tundra DC 4X4. Has had the light reset countless times.
I took it to Discount Tire and watched the guy reset light.

it works for about 100 miles then comes back on.
All 5 senders new as of 2020. Can not figure this one out.

doing the reset, seems to clear out any previous malfunction.

any ideas?

 

Can the tire folks check the batteries? Did you use OEM sensors or Amazon/ebay? I've purchased aftermarket and had them last less than a year due to old balleries in them.

 

They spent about 15 minutes on the car. Went and checked every tire with some handheld tool. Bought the sensors from them.
Very reputable Company.
Everything checks out. According to them.

 

DT sensors should be good. Gotta be the receiver in the truck. Loose connector possibly?
Whatcha flyin at AA? I just did my 20 at NJA.
