TPMS nuts are one time use only - careful when getting new wheels

When I got my new wheels I watched the guys transfer over the TPMS sensors which was easy enough and they used all the same parts from my old wheels. I unfortunately looked up the TPMS section in the service manual afterwards and found they say always to use new nuts and valve stems. The nuts have a little metal flange that deforms when putting them on and is intended for only a one time use. If you're getting new wheels you might want to order these parts first and give them to the guys changing your wheels.

I'm not sure what happens if you don't but I'll find out as I'm not going take my tires off again to replace these parts. I guess a slow leak is the possible danger. I'll keep an eye on my pressure for a month and see what happens.

Hello Vertrkr, what kind of wheels did you get? I purchased a new TPMS for my full sized spare and I noticed the valve stem and the TPMS unit were one piece. If we change the wheels do we need to change the whole TPMS unit? I believe I paid around $30 for the TPMS kit. When I inspected the unit, there appeared to be some type of battery...I'll take some pictures so you know what I'm talking about.

When I got my full size spare I bought the sensor and installed it myself. I then brought the rim to the tire place to get a tire mounted.

I was more concerned that they would properly seat the sensor or use the proper inch/lb torque wrench (and not the big lb/lb beast) which wouldn't have been accurate enough at the lower torque needed for the sensor.

You can reuse the sensor but need a new nut.

I traded my wheels for some stock Honda wheels that were black chromed:

You don't need to replace the sensor itself, the manual recommends replacing the valve stem, valve stem nut and valve stem screw. They should be tightened to 3 ft/lbs. The stem slips thru the sensor so they are not one piece although it may appear that way when assembled.

I decided to replace the nuts as it's the only thing I have access to now the tires are on. Just got off the phone ordering them, grand total is $9 for these.

Vert, you will probably be ok. Most manuals also recomend changing the brass washer on the oil drain plug but I have been using the same one for years without failure.

Ya, I think you're right. It's been two weeks and I would have noticed a slow leak by now so all is probably just fine.

Turns out those nuts I ordered for 9 bucks are the wrong part, Honda has the schematic wrong and those are actually the valve stem caps, sheesh. I canceled it and am calling it good.

Ok so now that winters over I bought some steel rims for winter tires. (Snow will be back in the fall :eek::()
From what I could find online looks as though Honda dealer gave me the correct TPMS sensors. (part # 06421-S9V-A03) I tried putting them on the rims and with the nuts finger tight the sensors were quite loose. According to vertkr, this is normal as the nut seems to have the little flange inside it that will deform when torqued.
So one question is... when I torque the nut, will this also torque the stem to the correct spec? or do I have to try and hold the stem from turning from the inside of the rim? What is the torque for the stems?
Next question...how much is 3 ft/lbs converted to in/lbs? (12in = 1ft so 3 ft/lbs = 36 in/lbs? Is this correct?)
Might be stupid questions for some, but I'd rather ask then buy again.
Thanks for any help.

See the attached file. Page two... All your answers are there... :)...

You're welcome....

Many thanks X, that was a quick response.
This file is for alloys but a guess it's the same for steel wheels. All the torque specs. are the same for all wheels.
Also, the torque wrench I have doesn't go lower than 10 ft/lbs. I can get one with in/lbs. Does anyone know how much is 3 ft/lbs converted to in/lbs?
Thanks again.

Opps. Sorry I should have read more.... here you go.

Yes... 3 ft/lbs = 4.09 Nm =36 in/lbs

A precision tool that goes that low costs about $130...

The alloy document is for when you switch over to those using your existing TPMS.

You can get an in/lb torque wrench at Sears for about 60$ maybe a little more, that will work just fine for the task :)

Or I can borrow one from work for free! :D
Once again X, you da man! :cool:

Not a problem... I recently went through this process when switching from my old alloys to some new '08's.

I've got some dandy snow tires that are mounted on the original Honda alloy rims that came on my '07 EX-L, and I'm thinking I'll just leave them mounted for next year and buy some fancy new alloys for the '3 season' tires...

So, I've been doing some research on the TPMS situation and looking at maybe buying a set off of E-Bay. Since I want to use new valve stem nuts, etc., and the biggest seller of 'used' TPMS' units states, " WE DO NOT SHIP TO CANADA"...I'm thinking a new set might be the way to go.

Question is, can someone confirm that '(part # 06421-S9V-A03)' is correct for a 2007 with alloy wheels? Does it matter that much if they are for a 2008 instead of 2007? Would any (Honda Ridgeline) TPMS sensor work on my 2007 EX-L??

Thanks,
Jim

Jim, first of all I would recommend that you abstain from purchasing used TPMS sensors. Two reasons for this is a) relatively low cost of purchasing new sensors from Honda dealer @ $45/each, b) limited lifespan of sensor batteries that range anywhere from 7 to 10 years.:(

Honda part no.06421-S9V-A03 TPMS sensor ass'y is limited for use with the thinner-walled stamped steel 17" wheels which were standard issue on the entry-level '07 DX model (CDN-spec). Honda part no.06421-S3V-A04 TPMS sensor ass'y is limited for use with the thicker-walled cast aluminum 17" wheels which were standard issue on the higher-end '07 EX model; the latter being the model which I personally used when mounting my aftermarket 20's.:)

Thanks Andy, appreciate the input. I had pretty much decided to go with a new set...now I have the 'correct' part # I'll have a look around to see what is available.

The fun part is trying to decide on the new wheels! Do you use the guys on Henri Bourassa at all?

Jim, this is the site I got my info from

Hope this helps.

If you are referring to Lazer Auto, I know them and have purchased many items from them. They are truly down-to-earth guys and can help you with your selection of rims.
http://www.lazer-auto.com/

I purchased my rims online from Wheels West of British Columbia. They have super prices and great service.

Those are the boys...Mike and Dan, just wasn't sure about 'naming names' on the board...

Yea, good guys, knew Mike from NDG in the 80,s when he was first getting started.

Thanks for the help,

Jim

Nope, used all my old stuff when I put new shoes on.............

No issues here ???

By the way, slight update to the pdf that xridgelinex posted above:



Use Torque Screwdriver to
Tighten TPMS Valve Stem Nuts to Spec
Currently Applies To: ’08–09 Accord, ’08–09 Civic,
’07–09 CR-V, ’07–09 Element, ’08–09 Fit,
’05–09 Odyssey, ’05–09 Pilot, and ’06–09 Ridgeline
EDITOR’S NOTE: This article replaces “Use Torque
Screwdriver to Tighten Valve Stem Nut” in the
February ’04 issue of ServiceNews.
To properly install a TPMS valve stem, you’ve got to
tighten its mounting nut to spec. And to do that, you
need a precision torque screwdriver that can be set
to 36 lb-in (that’s the torque spec).

If your shop doesn’t already have such a tool, CDI
Torque Products makes one that’s just the ticket. It’s
the Torque Screwdriver (Model No. CDI401SM). This
tool has a unique positive locking adjustment knob
that you can set from 5 to 40 lb-in. To set the torque,
just pull out the adjusting knob to unlock it, turn it to
the setting you want using the easy-to-read window
scale, then push the knob back in until it clicks. The
trilobular grip fits nicely in your hand, and it’s molded
in cool metallic blue. Snap on a 1/4-inch drive
adapter and an 11 mm deep socket (both
commercially available) and you’re good to go.

List Price: $305.39 :eek:

http://www.emaxaction.com/cdi401sm.aspx $183.23... Still :eek:

I reused my TPMS nuts after I had my rims powder coated. I tightened them until air didn't leak out around the valve stems.

No problems at all with my hand tightening method in a year and no reason to buy a $305 tool, especially since you can buy practically the same tool at Harbor Freight for $30.

Agreed. Free is always best.

I know you didn't just say that with a straight face, right?

I know, I know. It should work for his purposes though. All Harbor Freight tools are good for at least 2 1/2 uses. (It's always that half a use when it breaks in the middle of a project that pisses me off.)

When I replaced my RT steel wheels with stock alloys I just transfered the sensors without any problems. I ordered new TPMS nuts from the dealer as you are supposed to but but they sent valve stem caps instead. So I just reused the old TPMS nuts. Don't need no fancy torque wrench to figure out how tight to screw plastic nuts onto metal valve stems BTW.

Can just the nuts be purchased somewhere? I called Honda and they say I have to purchase the complete TPMS assembly. If there is a part number for the nut that I can request or is there a sponsor here that sells them?

Thanks

Yes... The part (stem and nut which are both to be replaced) is about $6-8 each... You can get them at any good tire shop (I did on a new RIM/Tire combo using the old sensors.), any Honda dealer, but apparently the one you use, or here...
