Well, since the sensors in your '01 go "dormant" when the car isn't being driven, my theory (which remains neither substantiated or disproved) is that the bigger issue is how many miles are on the sensors, as opposed to how old they are.... If you just don't want to take the chance, best price for new ones will most likely be from Fichtner Chevrolet or Gene at GMPartshouse (both supporting vendors).

SOrry for the Hijack, but I have a Sensor question also. How does the sensor know which corner it is measuring. The reason I ask is I pulled the rear wheels tonight and noticed they were going the wrong direction so I have to swap them. The right rear now the left rear and left rear now right rear.

And on that subject, just in case it is getting late for me, the directional arrows on the OEM Goodyears should point in the forward movement direction. If the arrows are at the top, they should point to the front of the car correct?

I have a 2001 that I just put new tires and wheels on. I decided to go with new sensors, partly because of age and because I kept my OEM tires/wheels for "whatever". They are supposed to last 6-10 years, but for approx. $200 you can get new ones with your new tires and not have to worry about dismount/remount of a tire before it is bald.

You train the computer to learn where the sensors are. It then knows "which corner is which". I just trained my C5 with my new rollers.
