Tire PSI sensor battery replacement, DIY? Or Dealer

After the replies on my previous thread wandered off somewhere, I put the most likely source of the warning in my 2009 without a spare tire sensor on the 4 sensor batteries. Those must be very small, and after +/- 8 years (not counting shelf time), not hard to imagine them getting weak. I wonder if there is a way to check'em.....
Has anyone gone through the process of having them replaced? Curious what the job requires. Do the tires need to be dismounted? If so, too bad I didn't know about it a few months ago at the new tires recently put on.
Gotta love technology,.... And just waiting for this Artificial Intellegence to start coming on strongER, it's in the news and scary!

 

turn off TPMS and enjoy

Or spend the money on new TMPS sensors and get it programmed which requires tire removal
ebay has new ones for 80-160 a set

 

If "Turn off TPMS..." Was simple, I'd do it. Not interested in the wiring changes listed on this board to turn it off. Too bad Toyota gives the owners a system that will at some point cause them trouble, with NO simple way out except $$$$$. (5$, equals 4 sensors+dealer!)

Found this on a web search, among many others....... Interesting if you want to see what they look like.

Batteries are not replaceable. Any shop should have the capabilities to scan each sensor to see if it's dead or alive. Do it all the time

 

Saved myself some money and decided to put up with the light on the dash lol.

 

Never understood the sensors for everything. Just something else to break and cost money. I can buy 40 of those pen gauges for the cost of 1 sensor. Or I'll just buy 1 good digital gauge to read my tires. They way people are today amazes me. What did people do to check their tire pressure before sensors?

 

I saved a buncha money by.... just dealing with the light in the dash. I have the TPMS sensors from my stock wheels and maybe eventually build the pipe to contain them but I'm not that worried about it.

 

Toyota's TPMS OEM sensor's have a life span of anywhere from 8-10 yrs. After that well the dreaded tpms light symbol on your dash will just be there, staring at you, annoying your ass.

So either just deal with it or do something about it by (1) just strongly ignoring it?......... (2) just cover it up?........(3) just disconnect it?......or.....(4) replace all four sensor's (five if your spare has one) and as someone else has already mentioned, have the new ones reprogrammed, etc., the cost? .....well not cheap either $.

Forget about going cheap and trying to replace the batteries on them because that won't work either and even "if" you were to replace the batteries on them, the system would "still" need to be reprogrammed so basically.......your screwed.

 

a small piece of tape will cover that light forever!

 

I think they waited until it ran flat then bought a new car...

 

it has nothing to do with you or me, but the largest number of vehicle owners are idiots
and Ford spec crap tires at 28psi, and people died from tire failures because...they never check tire pressure
or do a vehicle walk around every time they drive...so they murdered the tires from constant low pressure
until they rip apart and ....crash at speed

it is a Federal mandate that all cars and truck must have TPMS when sold. if vehicle doesn't
have TPMS then TPMS must be retrofitted.

 

I believe you forgot the part about 2007 and up are required by federal law. There's no way I'm putting a tpms system in my 83 Toyota to sell it.

 

If somebody died from not checking their tire pressure then that's just natural selection. It's only a 30k dollar piece of machinery your still making payments on. Why would you want to take care of it? I say remove all warning labels and safety devices from everything and let's just let the idiots off themselves. Imagine the lanes opening up on the highway at rush hour.

 

Just pulled this broken sensor out of a Porsche Panamera. (Ugliest "supercar" on the planet)

 

it's not DIY unless you can remove the tire and remount yourself.

my local toyota changes $175 for an OEM replacement and labor

 

The issue with Ford and Firestone tires, mainly on the Explorer, is much more complicated than the owner not checking the tire pressure. Ford specified 26 psi originally, which was too low, causing extreme overheating of the tire and lots of tire failures at high speeds, and many deaths. There were also problems on the Firestone side in the manufacturing process. Read all about it here: https://en.m.wikipedia.org/wiki/Firestone_and_Ford_tire_controversy

I personally prefer no sensors, but other than folks here at TW and other "enthusiast" sites/clubs, most drivers don't have a clue. And, thanks to computer technology, there is no end in sight as far as nanny sensor/devices are concerned. You can't argue the potential safety aspects of V2V and V2I technology, but it also creates a lot of debate also. A little fun reading...

For my second TMI post of the day...

The first passenger vehicle to adopt TPM was the Porsche 959 in 1986, using a hollow spoke wheel system developed by PSK.

In the United States, TPM was introduced by General Motors for the 1991 model year for the Corvette in conjunction with Goodyear run-flat tires. The system used sensors in the wheels and a driver display which can show tire pressure at any wheel, plus warnings for both high and low pressure. It has been standard on Corvettes ever since.

FYI - According to the statistics, for every 10% of under-inflation on each tire on a vehicle, a 1% reduction in fuel economy will occur. In the United States alone, the Department of Transportation estimates that under inflated tires waste 2 billion US gallons of fuel each year.

and... Under-inflated tires lead to tread separation and tire failure, resulting in 40,000 accidents, 33,000 injuries and over 650 deaths per year. Further, tires properly inflated add greater stability, handling and braking efficiencies and provide greater safety for the driver, the vehicle, the loads and others on the road.

 

That interior tho...
