Bought a 2022 Carbon CX5 and realize it has no TPMS at all. It shows one on the center display, but it is dimmed indicating it is not an option on this model. Mazda 1-800 rep told me that everything is there for it to work except the car did not come with tire sensors. I went to my dealer's service department and the service tech looked at me like I was crazy when I said I wanted to add TPMS sensors to my factory wheels. It makes sense if the "TPMS" shows on the display options. Can anyone tell me if this is actually an option to add Mazda sensors to a 2022 Carbon CX-5? Thank to all.

 

Mazda technician checking in, your car 100% has in-wheel direct-measurement tpms sensors, installed from the factory, as required by federal law. If you are showing any tpms light or indicator, that means you have either A: 1 or more improperly inflated tires, or B a malfunction with the tpms system. Take your new car back to the dealer you bought it from and have them fix it. Thread/

 

Thanks for the quick response...FYI...When i gave Mazda my VIN number they said it was not ordered with a TPMS and that was why it is dimmed out on my console.

 

Interesting! Assuming that whatever dealer rep you talked to gave you a correct answer (lol) look for a button on the left of your steering wheel that looks like the TPMS symbol. while in Park, press *and hold* this button until it flashes/beeps and disappears.

TPMS systems have been a Federal Mandate since 2007.

Traditionally Mazda likes to use Wheel Speed Sensors instead of in-wheel direct measurement units, where-in the relative speed of the 4 wheels is used to estimate tire psi. Your model may use these instead, but I doubt your model uses WSS. Look at the valve stem (where you inflate the tire) on your wheel. If it looks metal, you have a in-wheel unit. if it's rubber, press it inwards (towards the car) hard, several times. If you feel it hitting the wheel, you have in-wheel units. If it bends freely, you have WSS and they might need to be re-set properly.

*after resetting the TPMS monitor, the car must be driven a few miles to determine correct correlation of the WSS.*

Interestingly, you can trick the WSS system by incorrectly inflating the tires and then resetting them to the "correct" position.

 

My 2022 Carbon edition definitely has sensors. Not sure if it has been decontented due to supply issues, mine got off the truck and was delivered the last week of February.
