99 TPS O ring size
Hey guys, I went to the dealer to get some new TPS O rings and was told GM no longer sells just the O ring - you have to buy the whole sensor to the the ring.
I thoght I read awhile back that these O rings could be purchased at home Depot and I thought (?) that post said they were size 6. I did a search and the only thing I could come up with was a size 9. Could be my poor memory or could be two different generation sensors.
Anyone know, for sure, what size the TPS O ring for a first generation TPS is ?
Thanks

Go to NAPA, or True Value Hardware or ant marine supply store. they all will have an O Ring assortment to select from..
Be careful, They cost about 6 cents apiece.

I did a wheel swap on my 99 FRC.
In our Home Depot there is a section with a lot of small o-rings, seals, connectors, etc. In that section I found a clear plastic small rectangular container hanging on the wall. The container is about 1" x 1" x2.5" and has 10 o-rings in it. I don't remember the cost, but I think it was only a buck or two.
The information on the paper liner inside the container is as follows:
Danco is the brand.
It says:
Repair
#9 O-Ring
5/8" O.D x 7/16" I.D x 3/32"
10 O-Rings Enclosed
#96726
On the side the SKU # is 3715596726
When I did mine i just removed the old O-rings and put the new ones in the same groove. Be careful taking the old ones out. They have been seated in the groove for years and are stuck. With a small blade or pick you can get the o-ring to start coming up in one section and pull it out. Be careful not to scratch the seal surface in the groove if you use a tool.
On the wheel, I just cleaned the inside surface where it sits.
I was most concerned on how tight to make the nuts. I found that value on the forum (the 2000 and older take 106 in lbs) ( the 2001 and newer is only 35 in lbs) and it worked good.
The sensors have been working and I have not had any air leaks since.
Good luck!
