Is it possible to replace a rusty valve core on the sensor without having to replace the entire TPMS sensor?

Thanks for your inputs.

 

Yes. A rebuilt kit comes with a new valve core. They're around $5 per sensor.

 

Cool! Thank you for the information. Looks better than spending over $300 to replace the entire sensor.

 

The sensor cost is $ 52.00 per wheel at Sewel. I just bought a set of 4

 

I'm sure they're the same but Sewell lists a different part number for '06+ and they're slightly more @ $59 a piece?

 

When it comes to rotating the tires do the sensors have to be re calibrated or setup so that it knows which tire is where? Also is there something in the dash that will show you the tire pressure of each tire or only when its low? I have a Silverado with TPMS and I have to reset it every time I rotate the tires by letting air out util the horn honks on each corner.

 

It doesn't care which tire is where, simply let's you know when one or more drops below the threshold. Nothing needs to be messed with when rotating the tires.

 

Thanks, how do you like those Duratracs you have on yours? Ive been wanting to go a better tire. I like the Nitto Terra Grappler or the General Grabber AT2's. I have those on my truck and its a pig in the snow. I also want something that will go a few miles. How are they lasting?

 

My CTS-V was the same way. It would tell me the individual tire pressure and if you rotated the tires you had to reset them so it could recognize the new positions. Sometimes it was a pain but I liked knowing the individual tire pressure.

The GX will only come on when it falls below the preset PSI.
