Off topic - Tire pressure monitoring system

Post  rsv1cox on Tue Nov 13, 2018 11:05 am

TPMS that little amber caution light on your dashboard.

Mine came on this morning on my 2007 Honda CR-V a keeper if I ever had one!

When I got home I checked the tire pressure in each tire and found them all within a pound or two of the recommended 30 psi.

Got on youtube and found this video:

Good stuff starts about 10 minutes in. I did not know the sensors had a battery, narrator says a sensor (government mandated) lasts about 5-7 years. Mine has lasted 11. Replacement cost $205 to $275 depends on who you talk to. Gets expensive if you replace all four. Each sensor has a different frequency.

Last summer I got a low pressure warning light (tire icon) on my 2007 Nissan 350Z. Checked each tire and found one down about 7 psi. Filled it to recommended PSI and it went out. Repeat about three months later. Took it to the dealer, said it was the sensor $205 OTD.

I declined. Seems to me a leaky tire, not the sensor.

I've hade several go rounds with TPMS sensors, OEM at dealer about 1K cost. Aftermarket sensors unreliable. The owners manual should tell you how to link new sensors to cars computer.
Some sensors require special equipment to link. The batteries should be replaceable. Don't even get me started on the new "keys"!!
I check my tires weekly, one day my wife said "funny little light on in the dash" it was low tire warning so worked for her.

Knock on wood so far since 2001 with first new vehicle and TPS I have been exceedingly lucky*... when I bought the 1987 Winnebago monster 40 foot that had very very small tires....I had to invest in top line Michelin tires that would take 80Psi and hold up to 22,000 lbs at 65 mph....8 Tires..2 front. 4 drive axle, 2 load trail axle...Camping world ONLY charged me $789 to install a TPS system in all 8 expensive tires

Best day(s) with a boat?

Best day(s) with a Giant RV?


BOTH are giant holes in driveway into which you pour time and money

*2016 Jeep Cherokee, left rear constantly reporting low..no sweat fill it some... next week low
service time at dealer...Hey Mr Fred your left rear tire has side wall puncture..no fix...replacement tire 2 days away

Fred sez...fine order and install and bill me...now get courtesy guy to drive me home...when car done deliver.....

That car was getting dirty...2016 with 10,701..traded this week for a Red 2019 same car newer bells n whistles...n smell grin

Bob, had exact same problem, took our SUV to Discount Tire, they found and removed a screw and patched for free. Sensor didn't need messing with. Sounds like the dealer was lacking work.

Thems is funny little things. I just replaced my tires, knowing one of my TPMS was broken. ACtually, the threaded tip that the valve cap goes on broke away from the base but stayed on properly. Anyways, I had the shop replace it, but while replacing another tire, they broke another one. So, I had to replace 2 of them that day. I had aftermarket ones installed for $94 CAD plus $24 CAD to program.

Here's an article that gives insight into TPMS repairs. It is called the rebuild kit, which is recommended to do when replacing tires. Parts you mention NEW222 appear to be a part of this kit, no?

Discount Tire: TPMS Rebuild Kits

Rubber TPMS Rebuild Kit:


There's another kit for the metal stem one, but I think you'll get the idea. Article is an overall good summary of TPMS. A decent shop ought to be able to replace the OEM module satisfactorily, IMO. My personal feelings are that if you are satisfied with the shop you've been using, there is no sense to cut corners on tire costs and seek out someone else, who may in the end be a real pain when problems occur.

My son had his tires replaced at Costco last week and they must have replaced those parts and kept the sensors in place. He found the old parts left in his car.

So I always wonder about batteries....atomic clock(s) AA x 2, TV remote(s) AAA x 1 or 2, Wireless head sets AAA x 2

Funny I actually have had the factory ( batteries included) TV remote or Toy controller no name brand AA or AAA last a lot longer than Ever-ready or Duracell.... but I digress

how come my TPMS bats can last 5 to 9 years???...and to tell the truth on my 2005 F 350 King Ranch was sold(traded) with the original Tires and TPMS system fully functional in 2016...that is 11 years on the 4 batteries...curious...what is the magic going on there

should google to see what chemistry..certainly not alkiline button cells they corrode pretty fast in my experience

Note since we retired we both put very few total miles on a vehicle any more...in my case between 4500 and 7600 per year. Renie a bit more in the 8k to 9K range per year

Batteries are crazy Fred.

Yesteryear (50's/60's) I might get 3/4 years out of a car battery. But the 2007 battery in my MG midget was coaxed back to life after sitting for 11 years. Got another three months out of it before it died completely. Quarter size button batteries are still good after 20 years but the AA batteries in my camera are gone in a month or two. Switched from Duracell to Varta "High Energy" and made in Germany with the same result. New smoke detectors feature batteries that last an advertised 10 years. We will see.

Maybe Elon Musk has the answer.

How's that new Cherokee working out? My early 30's something granddaughter just bought a 2014 with 100K+ miles despite my caution and she loves it. "Look it's got heated seats." Smile

Speaking of batteries going crazy, 2 years ago, I soldered in a new NiMH 4.8V 300mAH battery to the power supply board in my 1997 GeneralMusic WK2 hard disk MIDI arranger. It should have lasted longer, but failed recently. My arranger no longer was retaining its custom settings and user stored styles, I had to redo settings and pull styles from hard disk every time I wanted to use.

A cell within the pack had failed by swelling and leaking.


2nd cell in the NiMH pack went bad.


My trusty soldering gun, an old Sears item from a while back.


New pack in place, my arranger is back in use.


This is what the arranger looks like.
