  1. Solved. The culprit was DC-DC for dashcam. Ford Edge 1 generation has common 315 MHz antenna for TPMS and Key Fob and very sensitive to Electro-Magnetic Interference. Now Key Fob distance is 20 meters and TPMS reads all tire sensors without issues.
  2. I have spare SJB from another Ford Edge 2008. I dissembled it and I guess it is tpms antenna:
  3. Thanks for replying. 2008 Ford Edge AWD SEL I had the issue with TPMS with error message. I replaced sensors 3 times. BTW I see the issue is not in sensors. I use forscan app +OBD reader to read all PIDs for tire pressure sensors. All sensors values (LR, LF, RF) updated, but RR sensor value (located most distance from receiver) updated very seldom. If RR doesn't pull values in 20 mins SJB considers it as fault. I suspected TPMS receiver. I know it is located in Smart Junction Box. I guess the TPMS antenna for this model is inside SJB. Is it correct ? Now I have another issue: Poor Key Fob Range. Before I could lock/unlock in distance ~20 meters. Now I can do it only in 1-2 meter. I replaced a battery in key, but the same result. Are there some workarounds to fix it ? Should I replace SJB in this case ? According wire diagram TPMS and RKE use the same antenna (315 MHZ) Check wires, connections, fuses ?
  4. Sometimes I have 'sensor pressure fault' . Replaced tire sensors 3 times ! I watched for sensors values and RR sensor didn't update. As far as I know tpms receiver located inner Smart Junction box ? Where TPMS antenna located ?
