TPMS Sensor...

[Melbone1]

I just recently bought a 2014 Ram Sport 1500 quad cab, and I have been noticing the tire pressure sensor going off like once a week,
I inflate the tire to 39 psi and then maybe a week later it goes off again, and it varies its not the same tire all the time.
Has anyone has this issue with the TPMS?

I guess the question is did the psi get below 30? Might be going out, it is 7/8 years old, those batteries don't last forever.

Being as you live in a colder climate
If your tires are inflated at the minimum pressure, the air pressure will set off Low Tire Pressure Indicator on colder mornings.
If you drive until the tire heats up, the indicator will turn off

This same thing happened to me a few years back, i had to escort a semi truck carrying part of wind power generator, from San Diego to West Virginia.
One morning when we were in Coal Run, Kentucky, it was a bit chilly
I was concerned that one of the tires was going flat, we did the soapy water test, etc., then one of the other truck drivers told me to drive on the low tire until we reached the next town, When we did that, the warning light went out

Go back to the dealer and tell them about the issue. You should have 30 days warranty. If the psi reading is dissapearing from the screen they may need to replace one or more sensors. If no warranty, a reputable tire shop should have the sensors in stock. I've had to replace 2 of them in December last year. $60 each at my at my local Americas tires, $22 labor. Total with tax $151 for both of them installed.

Mine was doing this occasionally. Still does it randomly. It’ll stop.

If they are aftermarket sensors, replace them with OEM, some trucks are sensitive and the slightest radio frequency interference with set off the sensor.

I fought this issue for almost 3 months on my 11. Finally bit the bullet and replaced the aftermarket sensors with OEM at great expense.

Once replaced, no more issues

Mine is on all the time, don’t care because I run 40lbs front and 38 rear remember tire pressures vary with heating and cooling so a cold morning less air, afternoon warm up, more heat more air. You can switch to nitrogen which helps in pressure values if you feel it’s that important.

If you want new TPMS for about 2013 or 2014 & newer
You would be buying Schrader TPMS
If you buy them at the dealership, you will be buying Schrader TPMS in a Mopar box

Ok, but don't they have to be programed?

No they are automatic after you drive a few miles

 

[Melbone1]

Oh ok, I found some on Amazon.
Thanks

When i had mine installed, the tire guy walked to my truck with a hand held device & he held it right close to each wheel & pushed some buttons
The reading on the EVIC showed the correct PSI after that

I've got a 2014 ram 1500 also. Recently one of the tpms stopped working. I tried raising the pressure in that tire, then lowering it back down, but it didn't get it working again. Because of the age should I replace all 4 when I do it or just the one. I figure I'll do it sometime this year when I'm replacing the tires on the truck. I don't want to replace one and then have another go on me too.
