I have a 2011 Honda Fit. When I change tire, I broke one of tire sensor, anyone know if i can just replace the sensor myself? or I have to go to a dealer to do it?

And how much it cost to replace a new sensor at dealer?

 

Did you break the sensor or the stem/valve that goes with the sensor? If stem, try to get the stem only and replace it.

If sensor, you will need to get a new sensor and have it programmed to be recognized the the car. Any decent tire shop can replace the sensor/stem for less than $100 and have it reprogrammed to be recognized.

The dealer can do the same for more.

 

I broke one and replaced it myself. I bought the part from them. The dealer wanted to charge over $100 to program it. Basically charging an hours labor for 10 minutes of work. I asked if he could program a key to, since it was less than an hours work. He said it took a different machine to program do he would have to charge another hour. I bought my car from them and many accessaries and parts. It will come in consideration when buying another car.
I had Merchants tire program the tire sensor for $20. Many tire companies have the TPS programming tool now, so check with one of them. I looked at buying the tool myself and it cost way too much for me. Luckily since then my father bought a Snap on brand one.

 

Glad it worked out for you. Agree that many tire places have the tools to program a generic sensor. In fact, I think replacing the sensor/stem with generic one is better than going pure OEM because you can easily replace the stem/valve without having to rely on the OEM parts, like during weekend when the parts store is closed.

BTW, I had one of the sensor/stem replaced on other car from a local tire shop. It's less expensive than OEM sensor.

 

I used a oem sensor from my unfriendly Honda dealer.
