OEM TPMS Sensor Issue

[1500DFW]

I've searched the forums but was not able to find my exact issue so I thought I'd ask.

I have a 2019 RAM 1500 Limited. A couple days ago my right front TPMS sensor showed a fault. The truck is just not reading it. I just assumed the battery had gone bad so I replaced it with an OEM sensor PN: 68293199AA. I drove the truck around per the manufacture guidelines. It is still was not registering. I disconnected the battery, deflated and reinflated the tire, still no luck. I tried doing the roll test with AlfaOBD and no luck there either. I took the truck to Discount and their monitor is showing the sensor active and reporting the correct pressure. They were unable to get the ID from the sensor (as I was going to try to program it into AlfaOBD). I suppose I could break the bead again and look at the ID on the sensor and try to program it but that is a ton of work. I am guessing that the originally replaced sensor probably didn't actually go bad but that there's an issue with the truck. However all 3 other sensors work perfectly. My question is; has anybody had this happen before and is there any known fixes without taking it to the dealer? Thank you.

I believe, unless thinking of Grand Cherokee that there is a sensor near each wheel that picks up the pressures. Maybe look into that?

I have replaced all the senders in my truck in the past year. First 2 were oem, broadcasting on 433Mhz, the second pair was chinese knock offs.
All took several miles of driving before being picked up, no programming necessary.

The RFH is used in the TPM to receive the radio signals from the tire pressure sensors and sends the relevant values to the other modules through the Controller Area Network-Chassis (CAN-C) and Controller Area Network-Interior High Speed (CAN-IHS). The RFH module identifies the sensor position, receives the sensor data, compares the pressure data with the standard pressure values stored in the non-volatile memory, determines whether there is a problem in the tire pressure and stores the warnings regarding tire pressure and system faults. The RFH used the RF Data from the TPM Sensor and the vehicle traction control module wheel speed data to determine the location of each tire pressure sensor. When a sensor is installed in a tire on the vehicle, the RFH can automatically identify the sensor and its location during the first ensuing drive cycle. Identification will take approximately 20 minutes but the speed of the vehicle must exceed 24 km/h (15 mph). The Kit, TPM/RKE ANALYZER 2046300080 can also be used to program the new sensor identification number in the RFH module. The sensor Identifications (IDs) can also be programmed using a Scan Tool.
