Service Tire Pressure System

[Coldfirex]

Howdy,
I have a 2019 1500 5th Gen. The "Service Tire Pressure System" warning came on about a month ago, and show my rear passenger tire just completely gone.
How should I troubleshoot this?
Appreciate any help.
Thanks

Sounds like one TPMS sensor has given it up.

I'd replace that sensor with a new one.

 

[Coldfirex]

Know of any videos that show how to do this?

Unless you plan on dismounting the tire from the wheel yourself, it's a tire shop job.

I have a 2018 Ram 1500 with 58,000 miles on it. I was just wondering how long the TPMS sensors typically last. Mine are still working fine, but in not too long I will need new tires. I've seen people that seem to go 10 years and/or 100,000 miles or more with the original sensors, but I was just wondering what is typical.

It's probably a moot question, because the obvious answer is I should replace them next tire change. Especially since I don't drive that many miles these days, and the new tires could be on for a number of years. But still curious what people typically get out of the originals

I like TPS, but we did without them for most of the time that there have been autos & trucks! Eyeball the tires, hand held pressure gauge, pump / compressor. I would get them all replaced when one went, if affordable.

I never had TPMS before I bought this truck, but I love having it. In fact they've helped me detect slow leaks, and I may have one right now. My front passenger side was showing a little bit low about a year ago, and that led me to find that it had a small puncture. Just today I went for a drive and my right rear was about 4 PSI low. I came home and checked it with another gauge, and the TPMS was accurate. I aired it up, and I'll see what it is tomorrow. I also added TPMS to my motorhome after I got this truck.

From all I have read the battery in a TMPS last a average 7 to 10 years !

I had 1 go out in my 2015 a couple years ago and did all 4 same time !

I know it is commonly said that batteries last 7 to 10 years. My first car that had TPMS was a 2006, it did not need new TPMS sensors until 2023 and it had 155,000 klms, so 17 years. My current 2015 car still has the original TPMS sensors in it and is at 100,000 klms (65,000 miles). The other 2 vehicles are 2020 and 2021, so still original TPMS.

You can buy OEM TPMS units from Rock Auto. A tire shop will charge you about 25 bucks a tire to install and re-balance your tire, or you can wait for the next tire change. I see no point in changing a TPMS out early as if it goes out it has zero effect on the vehicles drive-ability.

Funny when I had my tires replaced recently, I was having issues with passenger side front losing air. There was a nail in the driver side front which held air the best of the 4. My new tires are great (S/B for the price!) They do vary a pound or two as they warm up, and the 2 on the sunny side of the car are always higher to start. A credit to the TPS accuracy - things we never knew (or needed!) in olden days!

If a tire shop is taking the tire off to replace the sensor they are making a lot of work for nothing. You can breakdown the tire, change the sensor and re-inflate in less than 10 minutes.

All the factory mopar sensors have a screw mounting system that is universal and you don't have to change the stem to change the sensor. You can if you want but it's not required and that means no re-balancing or other services. As the tire doesn't need to come off the wheel.

I changed four sensors from ram to jeep in under an hour over the Thanksgiving holiday. Took longer to take the wheels off the jeep than it took to change the sensor.

Mopar sensors last 7 to 10 years, I wouldn't use anything but factory on this item.

I never change the stem, unless it leaks..

This type of tool makes it easy

Cool, that is info I did not know because I haven't done TPMS on a Stellantis vehicle so far and I have never had new TPMS installed other than when I was putting new tires on. Interesting things is, I would think this would apply to a lot of other vehicles too. Thanks for posting it, learn something every day.

Yeah dad was an auto dealer, back in the day, tire changer, balancer, whole 9 yards. I learned the hard way, doing things twice sometimes 3 times, till I matured, and saw things don't have to be overly complicated, unless you make them.

Just like ram and jeep, you think they use the same sensors, no that be too easy. Different mhz, mid year changes, I guess eventually they will figure it out but maybe not, it could be by design.

Well I found I do have a puncture in the middle of the tread. Some small nail or something. When I soap it it's leaking slowly. I didn't pull it out, I'm just going to start shopping for tires. Last time I had a puncture fixed the tires were just under 5 years old, and they were almost not going to patch it. Now they're about 5 years 6 months old. But again, the TPS did alert me that I had a leak, so it's a valuable tool. I'm pretty sure I'm going to have them replaced with OEM when I do the tires next week, so I'll check out prices.

Called America's Tire. They sell several brand sensors like Continental and Dill, all for $63 installed. They said if I bring in sensors they will install them for no extra charge, but cannot guarantee they will work. So now looking for OEM Mopar sensors I see some at 433 mhz, and some at 434 mhz LOL!!! Also many warnings of counterfeits on eBay and Amazon. Does anyone have a place you've bought legit Mopar sensors for a 2018 1500 Tradesman with stock steel wheels, and know why there's 2 frequencies? Mine are rubber stems, so I assume I need the snap in ones?

Well after doing some research I ordered some Goodyear Wrangler HPs from America's Tire for next Tuesday, and I'm going to have them put in some alligator TPMS sensors. I could buy them cheaper myself, but if I buy them there they will make sure they're programmed, and if they suddenly don't work they will warranty them. Little over a thousand bucks for everything. Also, some of the sites where I saw OEM Mopars, many of the reviews said they didn't work or the batteries were almost dead. At least this way if they don't work I'll just take it back and say change it.

 

[tap4154]

Just to follow up: I've had the Goodyear Wrangler HP's installed and they ride beautifully, and are very quiet as well. They were made in May of 2025, so 6 months ago, and fresh.

They installed the new Alligator TPMS sensors and programmed them. They scan the sensors, and plug into the OBD port. Within 3 miles of driving away from the shop they all popped on, and are updating real time. They warranty the sensors for 6 years or 72,000 miles. He said if they go out just bring it back, and they'll put a new one in.

So I'm happy so far!

Going thru this TPMS issue with my wife's 2019 Rebel!
Seems like the cold weather here makes the system act up however the monitors are original.

Just had new tires put on a few months ago.Wish Discount tires would have said something about replacing them.

I'm not positive, but from what I've read online they will install them for $63 each, even if you've already had your tires installed. Just call and ask.
