Anything special do I need to know about when replacing all 5 TPMS?

[Ogbassist182]

My air pressure warning light is blinking which means its malfunctioning. I am going to replace all 5. I found these. I am putting new tires on my ride, well they get here tomorrow, but I will wait to put em on so I can do it all at once. I will be getting a shop to put my tires on so hopefully they give me a break on installing TPMS. Do i need to buy anything else with these and are these the right ones for my 07 sport 4x4? I don't want them to take all the tires off and them end up being the wrong ones. And if anyone knows were to get them cheaper that would be amazing! Thanks in advance for the help.

Do you self a favor and just disable the system and it will save you a headache down the road I did after just about doing what you are doing. I just check my tire PSI once a month and also my spare tire, that also keeps the tire carrier in good working order (small amount of lube oil when its down)

If I disable it, will the light go off?

Yes forever unless you reactivate it.
Here is the link on how to do it.

It should only take 30 minutes to do even never doing it before (that's how long it took me and I am very anal about my work)

Yeah I read that post. I ordered some Scotchlocks. Hopefully I ordered the right size. I got the 16/14 gauge, you think that'll be the right size? I think they are blue. They look purple but I think they are blue. I read on that post someone said they used the blue ones and they worked so we'll see.

I paid $53 per sensor from Tire Rack, but they were the exact same as the OEM version. If / when you replace the TMPS sensors, you also have to update the truck's own board computer with the serial number of each new sensor (write the down before they are installed)

I bought an ebay "MINI-VCI" cable for the OBDII port (See here for more info on the cable)
and followed the instructions in a thread on a lexus site on how to download and install a version of the full toyota "Techstream" software. This software let me update the TMPS info myself, and it gives me access to lots of data, info and diagnostics about the truck.

If you don't get a cable and get the software running, then you'll have to pay a shop to program the new sensors for you.

The sensors just screw in to the rims... they are dog simple to mount while the tires are off.... but I guess it depends on the shop as to what or how much they will charge you. If they have to program the sensors (instead of you doing it yourself) then they will definitely charge you.

It took me about 45 minutes to install the Techstream software and make the suggested changes in the thread that I linked to, to get the software working on my computer. If you're not very comfortable working on a windows box (like in the cmd shell), then the installation might be a bit daunting. It depends on your skill level and familiarity with PCs.

I personally like the TPMS on my 08 limited. In techstream there are settings that factor in the outside temp, and whether the tires are hot or cold. So the TPMS works very well for me.

I previously had an '04, and it was a real pain, because everytime the weather got cold (winter cold), the TPMS light came on, because the cold weather lowered the pressure in the tires (I think that's called Boyle's law, if I remember correctly).

However, on my 2008, Toyota made the system MUCH smarter, so it knows if the low pressure is due to it being cold outside, and it doesn't bug me by showing me the low pressure warning. It's much, much better.

Yeah, im just gonna disable it, I check my tires regularly.

[BOSMECH]

Blue ones will work fine.

I have a question about this system. Could you remove the sensors from the four regular tires, and leave a sensor in the spare? The computer would only see one signal, and if the pressure was good in the spare there would be no light?

 

[radlynx]

not a good idea to disable it. during long drives, it's a good idea if you can tell if your tires are loosing pressure. remember, when you are driving and you are not aware that you have low pressure, chances are you will overheat the tire and cause a blowout which can get you in an accident. keep it for your own safety. it's not much to spend.

I don't know the answer to that question, but I suspect that the TPMS indicator would either flash on and off or stay lit if it can't get a signal from five sensors.

I am experimenting now with my spare. I am trying to figure out the distance from the vehicle where the light would come on. I put the spare in my pickup, and drove it a mile up the road and back. The wife was in the 4 runner, and she said the light never came on. i will continue to increase the distance I travel, and see what happens.

Yes because until the TPMS was invented there were millions of hapless drivers who never checked their tire pressure and thousands died every day. Oh the wrecks by the side of the highway...Oh the humanity.

By the way it's losing not loosing.

If you are too stupid to check your tire pressure once in a while you are too stupid to drive.

The blue Scotchlocks worked fine.

Thanks for correcting me on the wording. I didn't realize it until now and read it again. My honest mistake.

I disabled tpms. It took 5 minutes. and like 10 cents.

I think that was a good choice. I am still experimenting with mine. My spare is now up at the house, about 50 yards from my shop where the 4 runner is. There is no air in the spare, and no light on the dash. It has been a couple of days now, and still no light.

Maybe the issue isn't being out of range. Maybe it's being in range and receiving a signal indicating low pressure.

Checking PSI once a month is fine, until you hit a nail on the freeway and begin to lose pressure at 80 mph.

Exactly. I was 45 mins into a 1 hour drive when my light came on. I pulled into the first gas station and was down to 20 psi already. Aired it back up and it got me the last 15 mins to my destination where I changed to my spare. I had a tire drop quickly in my Tacoma and didn't make it to the side of the road in time, which resulted in destroying a tire and waiting a week for a replacement to come in.

I get the sarcasm, but there is a difference between blowing out your tire on your way out camping and off roading leaving you with no spare in the middle of nowhere, and pulling over quickly enough to prevent damage. There's also a difference depending on where you live. A blow out at 60-80 mph in Southern California is likely to get someone killed because of the density of the freeway. I literally noticed no difference in 40 psi to 20 psi when my light popped on and I was moving at a good clip.

To each their own. I usually have my son in the 4runner with me. Keeping a nanny light to prevent catastrophic failure in the event of a blowout is far more important than wrecking my car and potentially killing my son, myself, or someone else on the road.

I think you are correct. I was just curious to see if it would actually know that the spare was missing. I don't think it cares.
