TPMS Sensors

[bayouguy71]

This may seem like a silly question but....

 

I just swapped out my summer / winter tires and my winter tires have TPMS in them but I couldn't get my tool to reset them.

Being that the GM's are behind Chrysler in that they are not smart enough to know where they are on the vehicle without being told is it really a big deal if they are all working and reading?

 

I ask because in my head I thought for sure I would get a TPMS error on my way to work (about 13 miles) but then I realized I may not because a signal is still a signal right?

They may all read fine but just may not be in the correct locations?

 

Am I correct in that assumptions or should I expect a TPMS error anyway?

Each sensor has a unique sensor ID.  Your truck has a table that these sensor ID's are written into when you do the sensor learn procedure.  If you removed the sensors from the vehicle (as they were pulled with the wheels), you will get a TPMS light after you drive enough.

 

Having said that, if you put your old wheels and tires in the bed, your truck will go on reading them and not give any codes or lights.

 

When you perform the TPMS learn procedure, what you are doing is telling the truck which sensor ID to write to memory that each wheel location (LF, RF, RR, LR) in that order.

Yep, figured that out on the way home when the truck finally threw the error
Took 15 miles and 2 key cycles.
Guess I get a new programmer

Have you run this winter wheel set before or are they a recent purchase?

Last year's set but as kseisel pointed out they get get coded to the to the vehicle each time you relearn them.

New tool will be here Wednesday, we will see if it is the tool or the sensors that wouldn't let me teach them.

well, new teach tool today and no luck, tried 2 batteries even.

this will be my 3rd winter with these tires and have had no problem teaching them until this year.

 

I tried all 4 tires in every imaginable position I could manage.

I have a hard time believing that all 4 went bad at the same time?

I even unplugged my range disabler.

 

so, based on this what sensors are everyone running on their wheels, I see MANY to choose from.

I have ACDelco 13598771 in them right now, should I look at different / better ones?

I am going to stop at the dealership tomorrow and see if they can teach them.

 

I can't stand that little light in my dash

if you can just lean your summer tire against the side of your truck and see if you can relearn them, if you can then you know you have bad sensors in the winter tires

[bayouguy71]

well, stopped at my local garage today and had him ping the sensors, no response from all 4 tires

Time for new sensors I guess

 

He recommended VDO or Autel?

if its just a winter set forget it. so you have a little light on the dash, it wont hurt anything. I did that with my RWD G35 for 7 years.
