Should I replace my 2yr old TPMS when changing tires?

@Mendel Leisk Surely this could be determined by many other sensors ie VSC etc.

I do generally agree this system is sound - apart from Toyotas unsmart implementation to not auto learn new IDs until perhaps 2017-18.

That is not ok. Also - replaceable batteries should be mandatory. It’s all in all not pro.

 

So who's going to design them? YOU can do it!
Something that only likely needs to be replaced once in the life of the car, and is inexpensive?
Unless you purchase aftermarket ones, then their is no telling how long those batteries will last.

You CAN replace the battery, it's just takes some time. There are videos on youtube on how to do it.
Remember you have to fill the void so to protect from the heat and possibility of the battery cell getting
thrown out and flopping around in the tire....

 

I love threads like this. Its easy to id the grumpy old men (some early onset). And some females who are under informed.

 

Easy to id the kids that think they know it all..... ignored...

 

Yeah he lost me at “early onset”.

I’d like to think I’ve developed a “surge pile” over the years, become less prone to knee-jerk reaction, separate wheat from chaff.

@bisco is the sensei in that department.

 

I'll keep mine as proverbial dead doornails and turn off the light on the dash.

 

Did they get you to change your blinker fluid or just a top up?

 

That is just sad mansplaining and misogyny. And how do you determine that I am so under informed?

Especially @ASRDogman answer makes me realize this forum is just full of old men who think they know it all.

It’s like an answer from a 10 year old brain.

Toyota implementation of TPMs is terribly stupid and bad on gen3.

Any sensor without possible battery replacement ability should naturally be auto learned IDs when replaced.

But you wish to explain this with a wish consumers should redesign it. That’s almost trumpian. Aha.

Since y’all disagree, please mansplain why this system - that requires techstream to learn - is good.

 

I agree, but too bad you had to throw in your ideology.

 

still, it’s the norm. So here we are.

Didn’t take me long to come to same conclusion, but my take: if you take away the TPMS system, what happens? Not much. You’ve lost the convenience of an early-warming system, should be more vigilant, check your pressures regularly, and so on. But life goes on.

 

I just ordered 4 ‘Toyota’ tpms sensors off eBay. 50 bucks each. I bet they’ll turn out to be counterfeit.

 

Techstream is NOT required. Any scanner that is capable of writing the tire sensor ID numbers into the TPMS ECU can be used. A capable scanner does not mean it is an expensive scanner. The Autel AP200 scanner is capable of doing this, and it only costs $60.

 

My TPMS system started going bad after ten years. $40 worth of parts and $60 labor and it was good for ten plus more years. The fact it does not auto learn is no big thing when the tire shops have a $60-$200 Autel tool to setup the tpms ecu in the car. Safety is not compromised when a 20 psi tire with a nail in it is not felt by the driver.

That is my point others seem to rail against.

 

It's one of those things that work for some but most definitely not for all. If someone were to ask AI, for instance, the general rule of thumb is that the expected TPMS life is for 5 years in the world of somewhat certainty. Our plug-in had the unfortunate experience of a being on the short end of the stick as one of the set of four batteries died in under 2 years. That's most likely due to substandard TPMS quality batteries getting used.
