As far as I know, You can't just replace the batteries but have to replace the sensor. I'm sure someone else from the forum can give you a more difinitive answer though,

Someone on the Forum was offering to replace batteries at one time. From what I could make out it was a long and involved process.
Sounds to me like new sensors is a smarter way to go.

They are potted batteries...
which mean that they are encased in a resin like epoxy.
One has to use a dremel tool to grind it out, solder the new battery and re-pot it....

Yes, you can replace the batteries in the 1998-2000 sensors. Here is the link that has the instructions. Also, I have found that a small screw driver works fine for removing the potting material.

You can replace the batteries, but IMO it is easier to just buy a new TPS and be done with it. Do a search and you might come up with old posts on this subject.

For grins I replaced the batteries in my front two sensors when I had the wheels changed. I left the rears alone. So far they work perfectly. It's a simple swap if you take your time and don't booger up the sensor. Just make sure that the replacement batteries have the tabs welded to them to make contact with the circuit board. I got my batteries at batteries plus. They put the tabs on there for you.
