That year used the band type TPMS sensor and not the stem type. You had "one" installed and "only" that one won't train?

The train tool is placed 180 deg. from the stem on a band type.

I had a TPMS fault on my '09 FE that was covered under warranty and they replaced two of them. There is a battery in them so they don't last forever and probably not as long as they are supposed to!

I have no idea why your mechanic says it's the SJB. They do have a special TPMS diagnostic device but other simple devices just retrain the sensors. If a sensor doesn't train, it's thought to be bad. You should only need to replace sensors that won't train. If none will train, you have other problems.

Ford engineer here??? Never has been.

I also had this issue and was told by a dealership the SJB was to blame.

Apparently a low voltage from the battery can trigger electrical issues within the SJB (fry the board) and sounds like the TPMS's and driver's door lock are the first to go. I also had issues with the rear wiper. Had the SJB replaced today and everything works as normal. I did not install new sensors.

Not sure I would trust a mechanic to tell you that unless they had their hands on a diagnostic tool from Ford for your hybrid. Unfortunately a dealership would charge you both arms and a leg to plug up their diagnostics and a little investigation and find out whats up.

I do have exactly the same problems driver door lock, tpms and rear wiper won't work. How much should I expect to make it repair? Also, can I DIY?
