yes, it is a doughnut shaped magnet designed for this. I also had discount tire activate the sensors and still have the DTC code that will not clear. I even had them replace the rubber stems with aluminum and when that didn't work I went back to the DTC and found it was was not clearing. The DTC stays set after clearing, before I even try to learn. I don't think it will learn with a code set.

Replacement receivers are $300, so, if that is the case, i'll be pulling the wire.

Thanks,
Jim
