DavidZ - If the light is blinking, there is a fault in the system. Either the 5 sensors or the receiver is throwing a trouble code. Unfortunately the dealership is the only known place to diagnose it.
Let us know what you find out. If the light was a steady ON, then one of the tires is low on pressure.

The TPS Light is blinking. I have also tried the following:
1. Pump the spare to 37 PSI. The rest are 32PSI.
2. Discinnect the battery and reconnect back after 30s to reset the whole system.
None has solved the problem. The TPS Light in the end is still blinking. I have to go to the Dealer next week. I am 100% sure all the tires all fully pumpped. I really have a solid ride now!.

I have aftermarket wheels on my 4runner. After about 2 hrs of driving the tps light starts to blink, because my stock wheels are in the garage.
When I park in the driveway, I'm approximatly 10 feed away from my stock tires. It usually takes a few cranks to have the tpms light come off. My method is: see where the light is when the key is in the ON position and then start the car. If it stays on, I turn the car off and remove the key. Lock the doors and then try again.
It may take a few times before it stays off.
Has anyone had the dealer disable the light?

I took the truck on the the highway yesterday. After I speeded up to over 120km/h, I noticed the TPS blinking light went away. After that it did not come back.
SO here is what I did in summary:
1. Pumping up all the tire's pressure.
2. Reset the system power.
3. Driving on the highway.
I would say the step 2 is not necessary. It was my desperate effort to put off the TPS blinking light. I think the TPS was indeed triggered by the lower tire pressure at the very beginnng as I notice some tires, especially the spare was below 28psi. And on the day the tempature dropped down, the TPS was triggered. However the syatem may have a problem of resetting and it appears that the resetting treshold is above the 32psi for the cold tire. Thus high speed driving does help to make the light go away.
This is the second time it happened to me in two years time since I owned the truck. Well in the end, the light does go away. I think just doing step 1 and 3 should make it work properly in this situation.
Hope the information may be helpful to others.

I'll bet that unfortunately, the light isn't off for good.
As has been posted before, a blinking light indicates a system problem, and a steady ON light indicates a pressure problem.
The light could blink for any of the following reasons:
- Transmitter not registered
- Registered transmitter not being received (dead battery, spare missing, or you changed your rims)
- Communication error (it didn't understand what a transmitter said)
- Abnormal temperature inside tire (book doesn't say what that means)
- Receiver ECU failure
All of the above failures register a DTC code that you can pull with a code reader, even if the Check Engine light is not on.
The tire light will be on steady if the pressure drops below 27 psi in any one of the 5 tires. That can be caused by a leak, a flat, or the cold air making the pressure fall inside the tire. (The pressure of air drops as its temp decreases.)
DavidZ, I'd still go to a dealer or an auto parts store and put a code reader on it and try to find out what the problem was. The auto parts store will probably do it for free; the dealer will give you a hard time if you're not under warranty. If you get a code, post it here and I'll look up what it means. All of the tire DTC's are in the form C21xx.

Thanks for the info. I will go to the dealer since my rear wiper does not work. I do not know whether it was the result of my disconneting the battery power.
Anyway all three incidences happened to me, all had the TPS blinking. I never had a steady on before. However the first two times I just needed to pump up the air pressure.

The rear wiper issue could be as simple as the rear window not being completely in the "up" position.
Before taking your truck to the dealership, do yourself a favor and do a search on the forums. A lot of times your question can be answered here saving you time, money and stress levels

Yes. It is. I tried to lower down the rear window and up again. The wiper works well now. I also did a search on the forum and found that my situation is related to the fact that I did the disconnecting the battery and caused the system to reset. I also recalled that the front window up/down button beside the front seat was also flashing and I did a up/down the front window that fixed the problem. I did not know what it meant at that time. Now I know the explaination.
Who knows what else might be reset and may have any protential problem?
On the other hand since everything is fine and I am going to cancel the appointment with the dealer. That means I won't have the chance to find the error recorded as the result of the TPS blinking
Thanks everyone who helped!
The moonroof and the compass will also need to be reset.

Not well written owner's manual.
Yes I agree that the manual is not well written to make it clear and easy to follow. I have 2007 4Runner. I went through some sections, and there are many important pieces of information are not included. For instance, the tire pressure, what psi should be for the 4 tires, and the spare. And even better, what it should be for cold and warm weather. I live in Arizona so this information will help me a lot. Another missing information is the transmission fluid, dipstick (none listed in the book). Also not much information about changing your oil with the oil pan, oil filter. Another one is there is no information where to place your jack to jack up your car higher for easy access. This is only 3 sections out of a whole book and yet I found 4 major missing information. I think Toyota deliberately did this so that they can sell the preventative maintenance book (expensive), plus give the job to the dealers (also very expensive). I have 2001 Camry and its owner's manual is much better.

The tire pressure info is right there inside your driver door just like all vehicles.

One thing to also keep in mind is that the Toyota Limited 17" rims absolutely suck in environments with road salt. All 4 of my wheels have various levels of corrosion on them, and 2 rims/tires had slow leaks. I took it to NTB (since I have the tire warranty with them) and they said there were no holes in the tires, but the rims were no longer sealing properly to the bead on the tire. When we dismounted the tires, the corrosion had also extended into the bead. We wire-brushed the bead seal and rim on all 4 tires and that seems to have fixed the issue for now. Toyota's response to this was "You live in an area which uses road salt which can corrode the wheels over time. This is not a defect." At roughly 75k miles on these rims, I can expect to replace them around 90-100k miles. When I traded my Yukon in with over 150k miles on it, the rims looked almost new (driving for more years in the same environment).
I've also been experiencing problems with corrosion too. The techs at costco took a wheel I was having to fill up weekly and placed some soapy water on them. The result was bubbling all the way around the rim. They were nice enough to dismount, clean and remount the wheels, but dang.. I'm almost tempted to buy new tires/rims and disable the tpms system once and for all.
