New tire pressure sensor batteries
Well I changed two of my tire pressure sensor batteries in my 1999 coupe today and it was a snap. I used a small flat screwdriver to scrape off the epoxy and a pick set for the tight spaces. A paint can opener works great to pry the battery off the double sided tape.
here are the steps I took
#1
Make a line like I did on the back side. That line gives you plenty of room to expose the solder pads
#2
Using a small screwdriver slowly filet the small layer of epoxy.
#3
Take your time and work around the battery with the screw driver and pick set
#4
Once the area around the battery has been removed Cut the exposed battery lead and gently pry up the battery with paint can opener around all sides except for the solder joint side.Once the battery is loose cut the lead on the bottom
#5
Once the battery is out take your time and clean up the battery box area. be careful around the board area.
#6
Remove old battery leads with soldering iron and add a fresh bead of solder to each contact.
#7
Fold the positive lead onto the side and inset the battery positive down and line up the soldering points with the battery leads. Trim the negative lead as needed. I trimmed off 2-3 MM on mine.#8
Solder the leads, test them with a volt meter for safe measure and cover with a thin layer of hot glue. My old batteries were in the 2.89-3.02 volt range and the new ones are in the 3.44-3.48 range.#9
Fill in all nooks and crannys with silicone and smooth with a blade or putty knife. You are done
Tools and parts used
battery (digikey part # p030-nd) $3.68 each

small flat screwdriver
pick set
tube of silicone
hot glue gun
solder and solder pen
putty knife or razor blade
paint can opener (prys up old battery awesome)
The first one took about an hour to do and the second one took 40 minutes. it was a piece of cake. I can't wait to do the other two.
Hope this thread helped

I agree! There was no way I was going to pay over $400.00 for TPS
This was a very easy job. You just need to take your time and be careful around the board. These things are built to take a beating so changing a battery will make them just like new again

The tabs that are sodered on the battery I bought make it a snap to install.

The ones that I have not done yet took 10 seconds and 12 seconds to learn. The ones that I changed the batteries in took 6 seconds each
I had all 4 sensors in the same spot when I hit them with a magnet. Tomorrow time pending I will rebuild the other ones.
