2014 F150 5.0L 4x4
Rock auto has 2 motorcraft TPMS listed. A 433MHZ and a 315MHZ. Which ones do I need?

 

315mhz

 

That is unfortunate. The 315MHZ is more expensive. Is there some way to confirm that morehousej?

 

I can confirm it with the vehicles VIN number.

315 is correct. I bought a set when I replaced my rims.

search ebay, i bought a set of 4, new, never used sensors for my 2011, cost me $80 CDN and I think $10 shipping... it was free to ship in the US. There were several buy it nows listed for sets of 4 oem sensors, all new, not take offs. Watch for takeoffs because the battery life in them could be almost finished. Sensors have an avg battery life of about 5-7 years.... of course, all depending on drive time, and what temperature extremes they have been subjected to.

Also be careful, not all 315mhz sensors will workmake sure they are for the F150. I have 2 sets of sensors here from my old ranger, one set never used, they are 315, but they will not work.

 

It is the 315 MHZ like everyone else has said. The part number 9L3Z1A189A is correct per VIN number.

 

Get TPMS on ebay for sure. They'll be OEM and you'll save a ton of money. I got a set of for last time for $99 shipped.

 

Thanks for the replies, ordered a set on amazon today.
