Tire pressure warning light

Are you swapping two sets of tires (the all seasons and snows) on the stock rims?

 

You need to tell the TPMS system the codes of the 4 tires on the car.

Options:
(1) Wrong codes inserted
(2) Missing or bad TPMS

Problem is watching your cost in fixing. Cost can range to cheap to expensive (dealer).
Take your time to see if you can sort out problem.

 

I have no idea how to solve your problem, but let me know when you do manage to figure it out, because I have the same problem!

(I check air in all tires, reset TPMS, just sit in the car, and after about 10 minutes the warning light comes back on)

 

Yeah, with two sets of tpms sensors, EVERY time the wheels are swapped the car needs to be reintroduced to the sensors, either by dealership with proprietory techstream software, or some third-party hardware (@wjtracy has more info). Dealership will charge somewhere between $50 and $100 for this. Twice yearly.

There are other solutions, I believe there are third party tpms sensors, that can be "cloned", so the car doesn't know the difference. But that's maybe for another day.

I just have plain valves in my snows (on separate rims), but that's more difficult to do in the States.

 

Some of us have Techstream or some other way to read and set the codes.
Otherwise you have to go somewhere to have the service done.
The only way you know the individual codes if they are written down somewhere.
Some places have devices that can read the codes and set them

 

You could ask if they would do it for you if it their fault or willing to do you a favor.
You might find a tire shop willing to do a cheaper reset.

 

PS- if you keep the snows near the car it may pick up the signal each day

 

If you have to go through an inspection, and a tpms light will fail you, just show up with the wheels having the recongnized sensors, in the hatch, maybe under a tarp? Kidding...

 

TPMS wheel sensors typically use built in motion sensing to run them off when parked to conserve their internal batteries, so the cars system won't see the off mounted tires.

 

Hmm...so the problem above was that the OP probably does not have 4 TPMS codes set in the cars computer that correspond to the 4 TPMS units actually on the car tires. Do you think you have 4 tires with TPMS installed in them and the codes are set properly in the cars memory?

TPMS run on button batteries, but 3 out of 4 mine are going on 12-yrs old now so we are not expecting that in your case for a 2016. The TPMS can sometimes get damaged in a flat tire scenario.

 

Good point...but I am not sure if it is movement activated, or the car has to be turned on?
Seems to me you can keep your car in Park, and work with them (drain pressure and see reading etc.).
I have a static TPMS in my glove compartment contributing the reading for one of my tires.
Anyways kick the snow tire before you start the car. It does take a minute or two for the readings to register.

 

I run two ScanGauges with one being dedicated to tire pressures or temps. I’ve noticed that even when started and still in Park the wheel TPMS sensors usually are indicating something around a default of like -14 psi till you put it into drive and actually start the tires rolling.

 

Never had a flat tire.

 

Did it ever work for you?
If so, sounds like one went bad and you would need a reader (Techstream etc) to see what was going on.

 

Yes, it did work. I guess that one of the sensors is faulty.

 

Conceivably you could have the set the alarm pressure too high? If you take the pressures down to 30 psi and reset, that would set the alarms lower, and then pump up to what you want.

 

My OEM 16" rims with the summer tyres mounted, and the original TPMS are stored in my garage, and when my Prius (2009 Gen II) is parked overnight in the garage, the TPMS NagLight goes out, and flashes on, going steady after a couple of minutes, after about 30mins of driving away from the garage (the car is wearing its 15" steelies shod with Blizzak Snows (sans TPMS) at this time of the year). I invested in a set of these, which are put on whichever set of wheels are on the car.

They are great and show not only the tyre pressures, but also the temperatures!
