schrack Posted September 24, 2023 Report Share Posted September 24, 2023 2012 Ford Edge SEL AWD 3.5 - Recently installed new tires & 4 new Motorcraft TPMS Sensors. While trying to do relearn my Autel TPMS 508WF cant get the first two tires to scan & vehicle horn will beep. Third tire RR will scan into scanner, but will not beep horn & fails every time. It will beep after other3 scanned & keeps failing on the third RR. Any help appreciated. Quote Link to comment Share on other sites More sharing options...

The scan tool is designed to be able to read sensors from many different manufacturers, so it will read it regardless, if the sensor is alive. possibly a wrong frequency sensor? not a fun thing, having to replace a new sensor, but I suspect that is where this is headed. 1 Quote Link to comment Share on other sites More sharing options...
schrack Posted October 2, 2023 Author Report Share Posted October 2, 2023 Well thats what i thought. So purchased another set. Replaced the that wouldn't read with a new Motorcraft sensor & have the same problem. It will not read the third tire. So now two sensors that wouldn't read. So what controls the reading of the sensor BCM? Quote Link to comment Share on other sites More sharing options...

Swap #3 wheel with any other wheel on the vehicle (preferably 1 or 2) and see if the problem follows the wheel(sensor) or the location Quote Link to comment Share on other sites More sharing options...
Cerberus Posted October 2, 2023 Report Share Posted October 2, 2023 Also, which wheel are you calling number 3? Not everyone knows the correct sequence so it's worth asking Quote Link to comment Share on other sites More sharing options...
schrack Posted October 2, 2023 Author Report Share Posted October 2, 2023 Going to possibly go to local garage tomorrow if they can squueze me in $85 an hour, local Ford wants $165 an hour. The correct sequence is LF, RF, RR, LR, then spare. So wheel 3 is the RR. Keep you all posted. Quote Link to comment Share on other sites More sharing options...
schrack Posted October 7, 2023 Author Report Share Posted October 7, 2023 Went to the garage today. Mechanic was using a Snap On Tool. He was having the same problem as i did. Tried 3 different ways. Mechanic also scanned 3 new Motorcraft sensors & could not get them to scan & get car to beep on the third wheel. So the mechanic had a new universal schrader ez-sensor #33500 took out of box scanned beside vehicle & instantly the vehicle beeped, then scanned the fourth LR wheel to complete relearn. So he then broke down tire & installed new sensor. Long story short, like they were saying don't but Ebay TPM sensors. Paid the $134 bill , light still on. When leaving their parking lot light went out. I just find it hard to believe that 5 sensors out of 8 i ordered were bad, but seen it with my own eyes. 1 1 Quote Link to comment Share on other sites More sharing options...
