Tire pressure sensor handling during tire changing
I thought the 2001 C5 had the band around the wheel which held the tire pressure sensor but now I understand that the sensor is part of the valve stem.
Does the sensor/stem need to be removed and then reinstalled when mounting new tires, or is the sensor simply left in place on the wheel during the tire changeover?:confused:

Re: Tire pressure sensor handling during tire changing (mozin)
I don't know where this myth started (there was another post with the same misinformation recently).
It's not part of the valve stem, it's next to the valve stem on the wheel.
You might want to consider changing the small rubber donut on it (your local Chevy dealer wants about $5.00 for 4; AutoZone about .30 cents) when you change the tires, but that's about it.

Yep, got to be removed before demounting. Check out this site for more details on tire changeout details:

Thanks for answering my question. I thought I would get one response with a simple yes or no but your responses were great. :yesnod:

Re: Tire pressure sensor handling during tire changing (mozin)
Watched the guy change my tires the other day.
He didn't take the sensors off, but I did notice he was careful were it was positioned on the machine before he started stripping my old tires off. :)

Re: Tire pressure sensor handling during tire changing (mozin)
Ok, check out this site: http://www.hunter.com/pub/undercar/PPT/sldeshow.htm
Hunter is a manufacturer of tire changing equipment and this appears to be their bulletin regarding handling of EMT tires and, to the point, pressure sensors.
I've also seen tires removed without removing the valve/sensor.
One final point: if you're in a snow area and drive the car in winter, you might want to tell your tire guy to be verrrry careful trying to remove the core (pressure release mechanism in the center of the valve) as it may be corroded. The corrosion doesn't seem to affect sensor performance, but if the core is damaged in removal, the entire sensor is shot. Sadly, I learned this the hard way. If the core is stuck, it's better to have the tire technician bleed the air out by hand.
Good luck.
Steve :cool:
ps: replace the rubber o rings AND lube them with silicone grease.

Drop Top Dave:
I'm not sure what you mean...sure looks like part of the valve stem to me!

DropTopDave, that is damming evidence!! yup, it IS part of the stem!!! HeeHEe!!

HeeHEe!!
Here's a picture of the sensor without the stem -- because it ISN'T a part of the stem:
And here's another picture of the sensor WITHOUT the valve stem, being installed in the wheel. Notice the valve stem is on the other side, being screwed into the sensor:
And here's a picture of the two separate parts screwed together:
So, if you go to the parts book, you know, the one produced by GM, you'll find that the valve stem and the sensor have two separate part numbers, because, let's see...,
oh my, they're separate parts, with two separate prices.
That's what I mean.
Pretty "damming evidence!! yup, ...!!! HeeHEe!!"
Hope this helps. :smash:

Re: Tire pressure sensor handling during tire changing (mozin)
Thanks mozin, they're actually from the posts above with some commentary added for clarity.
The way I understood you're original post, I thought that you felt they were part of the valve stem, possibly inside the valve stem like the valve itself.
In fact, they're inside the tire, and the valve stem is screwed to them from the outside.
The "next to the valve stem" part comes in when it's time to reprogram them -- that's where you need to hold the magnet.
And remember, don't forget to change out the donut and lube it a bit as was posted by another member above.

Re: Tire pressure sensor handling during tire changing (EHS)
I posted this question in the Wheel & Tire section but it got no response.
Has anyone tried to revive their tire pressure sensor after using the flat tire inflation gook? There must be some kind of solvent that could be used to disolve the gook out of the sensor. Any ideas?

Tom-
From what I have heard, the solvent that makes the sensors work again is called "Money."
In other words, all posts I have seen say that the gook totally ruins them and you need to buy new ones. Hope I'm wrong.

I just bought two sensors for a 2001 and when I received them, the stems and sensors came as one, with one price, sealed in one GM bag :confused:

Re: Tire pressure sensor handling during tire changing (EHS)
The myth must have carried over from the C4 Low Tire Pressure Warning System (LTPWS). The sensors were attached to the wheel with a band. They weren't monitoring sensors like the ones on C5... they just transmitted when the pressure dropped below a certain point. Then a light would come on the information center telling you to check tire pressure.

Re: Tire pressure sensor handling during tire changing (Innocent Bystander)
I had my wheels recently replaced...removed wheels from car...took wheels 5 miles away...did not remove the sensors before removing EMT tires...mechanic knew what he was doing.... marked the sensors for location RF,LF,RR ,LR...took them home waited a week for the new wheels...installed sensors.... didn't even have to recalibrate them.

Re: Tire pressure sensor handling during tire changing (jawski)
I just ordered a set of S03's from the TireRack and they said that the sensors don't have to be removed but you have to be very careful not to damage them.
