TPM

[Deleted member 19354]

What are your thoughts about faulty TPM. I had it go off and on a few times this weekend no change in pressure. Car is still under warranty. Ya think this maybe covered?

Should be covered, yes.

Question first though - do you have a dashcam? Because apparently there's something about this car and dashcams that seem to cause pressure sensors to think they're failing. Specifically, at least in my case, the left rear.

Weird thing is that my winter wheel set "failed" FAR less than my summer wheels/tires (the winter ones are OEM sensors also that came with the white rally wheels from Ford).

This is creepy. Have you been spying on my car? Yes dash cam and yes passenger rear!! ?

I had something similar with mine when I installed my dashcam. If you restarted the vehicle after a fault it would go away. Mine was also left rear. Dealership said they couldn't do anything unless I brought the car to them with the fault active. I used the 12V in the trunk cause I would run the wire in a cleaner more hidden way than the socket in the front.

I ended up putting a ferrite bead around the power cable by the dashcam plug in my trunk and that solved my TPMS issue.

That's interesting. Might have to give that a try. I have a BlackVue set that is run off of one of their batteries. And the battery itself is hard wired, so I guess I'd have to put it on the power running to the battery? Might have to play with that a bit. Would be nice for it to stop being stupid.

That's my exact setup aside from the battery being hard wired into the car. I used to have my BlackVue hardwired into the 12V battery but it's too small to use reliably for parking mode and even though I had the box that cuts power to the dashcam when the battery voltage is low I still had it drain the battery and lock me out of my car. Using the 12V socket it provides power for 30 minutes after the car is turned off which is enough to charge the BlackVue battery to give me at least a few hours of parking mode without killing the Mach E 12V battery.

I put the ferrite bead near the dashcam plug because that was the easiest place to put it without getting ugly since the ferrite bead is slightly bulky so can't be as easily hidden within any trim. You should be able to put it anywhere along the cable going to the battery. Technically you want to put it as close to the device causing the EMI as possible but I have no idea where that actually is. I just put mine near the plug and did one wrap around the bead and then had no problems. The plug probably isn't doing any EMI since it's basically just plastic and metal to connect the wires to the socket pins (and an LED to show it's receiving power).
