Good day.Tacoma owners . New user here and I'll get right to the subject. Any useful info, out there, on how to defeat the pesky tire pressure light on my dash. I installed some nice aftermarket rims and tires on my 06 tacoma 4x4 double cab .It is due for a state emissions test in april 09 and it will come up as a code on the computer. I kept the wheel sensors.Is there a way to somehow fool them or perhaps short them?Any info is much appreciated. George

Did you install the sensors on the new rims?

Hi George,

You are very correct on "pesky." "PAIN IN THE ___" is how I described this one. Here's what I did with mine..

Please note that if the truck is still under warranty, Toyota will deny responsibility after this mod is made.

Start with all five sensors (..remember the spare has one too...)

Go to the hardware store and get a 6" long - 2" diameter piece of galvanized steel pipe that is threaded on both ends, and get two correctly threaded caps to fit the pipe.

Drill five holes in the pipe that are the exact diameter to fit for the valve stems. These holes should be very accurate. Mount the sensors with a little Permatex for a good seal. Be very careful not to get the Permatex on the sensor. Make sure to use it on the threads only. Also use some Permatex for a good seal on the caps.

The sensor system looks for differences between the different sensors, so you should be able to get away with putting about 30lbs of pressure in the pipe. This will keep all 5 sensors happy at once.

Wrap the pipe in a shop towel in case it bounces around at all, and put it in one of the cargo holds under the back seat. This way the sensors will talk to the engine computer and quit bugging you with that miserable light.

Good luck to you!

Vince

george,

I also forgot to mention that you will need to get a tap that is the same thread size as the external thread on the sensors so that you can make threads inside the holes in the pipe.

Any good hardware store should be able to set you up with a matched tap and drill bit set for for the project.

Also, use lots of oil when cutting the threads.

Thanks, Vince. Very Helpful . I'm gonna try it tomorrow. We have those nipples at work. I'll throw some plumbers putty on the end cap threads to seal up tight. Again, thank you, George

Hi George,

Glad to help.

Please understand that it's been almost a year since I did mine so details of the project keep coming back to me a little bit at a time. This being said, one other thing that I remembered from doing mine was realizing the fact that a small air chamber like this will fill up to 30psi VERY quickly. Go VERY VERY EASY when putting air in the pipe. I would bump it with your compressor in 1/4 to 1/2 second intervals. Since the system is looking less at the overall pressure and more for significant pressure differences between tire sensors, you might even be able to make the system happy with less than 20psi. Just take it slowly. I'm very certain that a piece of good galvanized steel pipe is much tougher than the air pressure you'll be working with, but let's not test the theory by cranking up the compressor.

Also, my tire pressure light stayed on even after I pressurized the sensors. I had to use a DTC code reader to shut it off, and it stayed off after that.

Let me know how it goes..
