Here is my change....
my sensors were not giving me an issue.
TPMS sensors.....I bought 4 'new car' take offs on ebay for $53. (original style)
I had them months on advance- for when I replaced my tires.
When it came time to replace tires- Shop changed out my sensors for $5 per tire.
So-- You may want to search online/ in store for sensors.
And then have the changed out when you have your tires replaced.
Or drive in to a mom and pop shop and see what they charge.
I have seen new a new replacement part # out for the OEM units.
The new ones are very cheap. I believe about $18 each.
