tire pressure warning valves and transmitters

Ok I searched several post on this but still not entirely clear.So I bought a set of 2017 trd wheels and 265/70/16 tires with sensors to replace my steel wheels and 245's that were on the truck.I set all of the new tire pressures but now I have flashing tire light at start that turns to a solid tire light.Do I have to take it to a dealer to register the new wheel id code?

 

3rd gen TPMS sensors won't work on a 2nd gen Taco. Your steel wheel TPMS sensors won't fit aluminum wheels. Steel wheel sensors can be installed upside down in aluminum wheels, but that's the Mickey Mouse way to do it.

Here is something I wrote a while back about how the TPMS system works.

Here's how it works. The sensors are 1 way communication. The truck listens to the information being sent to it by the sensors. The truck only listens to sensors it's been programmed to listen to. Let's call them Bob, Jake, Johnny, and Rafael. So, each sensor tells the truck what presure is in the tire. Let's say they're all at 32. When you push the button, the truck learns that 32 is normal pressure keeps the light off. Now, 1 morning Johnny is on a bad hangover and tells the truck he's only at 25PSI. The truck turns on the light to let you know. You give Johnny some pepto bismal(air), the truck is happy and turns out the light. On your way to work, there's a Tacoma beside you at the light with a low tire. That sensor is named Brittany. Your trucks light doesn't come on because your truck doesn't listen to Brittany.

So, when you get new sensors, there's 2 ways to make the truck happy.
1. Pull new OEM or aftermarket OEM type sensors off the shelf and program the truck to listen to them. Now the truck only listens to George, Paul, John, and Ringo. This programming can only be done by plugging into the truck OBD2 connector.

2. There are aftermarket sensors that have no name. It's like adopting a puppy at the shelter. Your dog Bob crosses over the rainbow bridge. You go to the shelter and adopt a new puppy and name him Bob. (The tire shop programs the nameless sensor to say, "Hi, my name is Bob") Now your truck still listens to Bob. Your truck isn't smart enough to realize it's a different Bob. He thinks it's the same old Bob, and is content and patiently waiting for Bob to go on a drinking binge.

 

Take the sensors that work with the truck put them in a pvc tube then seal both ends install an air valve into one end and Pressurize it to 40 psi and toss in in the truck put a rag in the tube so they don’t rattle around them put whatever wheels on there you want no more lite

 

Muddinfun, love that analogy, had me laughing.
$yoda$ that's the best way to deal with it, the old pipe bomb trick.

 

thank you. So i need to buy new sensors and have them
Programmed .where is the best place to buy the aftermarket sensors

 

RockAuto is a good place to start.

 

The only thing I can add to the very funny and informative post is that earlier TPMS systems were a little different than most current ones. Let's look at the system in my 2014 Tacoma for instance. I have four sensors named Moe, Larry, Curly, and Shemp. The truck knows them as do I and I reset the system with all four tires at factory recommended pressures last fall. After the first really cold night, apparently one (or more) of the boys weren't happy and I got the Tire Pressure warning light on my dash. Please note that all you get is a warning light and not an indication which sensor is showing a problem. Understanding that colder temperatures lead to lower pressures, I didn't panic because I was 99.9% sure nothing had changed. So, I checked all four tires and found all of them were down an equal amount. I told the boys to man up and stop complaining.

Newer TPMS systems actually tell you how much pressure is in each tire and thus which one is low right on the dash. This avoids the embarrassing need to walk around my truck and ask each sensor (by name) if they're happy or not. At least people smile at me when I'm at the gas station talking to each tire. Then again, it might just be because they think I'm an idiot.

One last point. Even though my truck cannot tell me which tire is low via an indication on the dash, plugging the appropriate diagnostic tool into the OBDII port will.

 

That has to be the BEST explanation that I have ever read!

 

So with that said by Too Stroked, if the year truck you have doesn't tell u the specific tire that's low, do the pipe bomb trick.

 

I run 2 Scangauge2s with an OBD2 splitter. 1 of them shows tire pressures and the other shows temps and stuff. I can check my tire pressures at a glance at anytime.

@windy ridge kennels Also worth mentioning, ‘06-‘08 came with a sensor in the spare. Since the batteries in your sensors are hanging on by a thread and you need to get new sensors programmed anyway, you might as well buy a new sensor for the spare and have it replaced at the same time. Many people have had good success having Discount Tire do their programming. There’s even a Discount Tire dealer that’s a member on TW. I have Techstream on a laptop and can do my own programming, but since you need to have the bead broke loose to install the new sensors, you might as well have the tire shop do the programming at the same time.

 

I just had Costco replace all five of mine. 2006 truck and they finally (well, maybe one of them died) went bye bye. $55 each (?) . My OEM ones were damn near magic to last 14 years.

 

Rarely do I find a thread that is current that is exactly what I'm looking for, and I don't feel like an idiot asking a question in a 5 year old thread... Anyway, just to clarify--the stock TPMS sensors that come in 3rd gen wheels cannot be learned by a 2nd gen vehicle?

 

Correct. No way, no how, not possible. Like trying to understand your cat when it’s meowing.
