Strange TPMS situation on am I crazy.

Tuesday I had new wheels and tires installed with no TPMS installed. Left the originals in the stock wheels and tires. I get home and dump off the wheels and tires and take off for work. Now I figured as soon as I got going the light would come on but it didnt.
Ok, wait till I get going down highway and it might come on, still didnt. After work coming home, still no light. Mind you I am not complaining about it, if it doesnt come on, good deal I guess.
Anyway, a question. Should'nt the light come on almost right away after starting vehicle or when you start moving?
TPMS light comes on with initial key on and then goes off.

 

Sometimes it takes a while. My other car it took a day or so to finally notice they were not there anymore.

 

x2, the system only queries the sensors every so often. So if they are nearby your truck at some point during the day (i.e. if they are in the garage where you park at night or something like that), then it will take the light a while to come on.

 

You would think the system would do a diagnostic check at start up at the very least. Of course if you park in or near the garage where your stock wheels are located then everything would check out okay but if your work is a fair distance away and you started your truck it seems the system should pick up the absence of the sensors.

 

I know jack about most stuff, but it seems to me that the sensor activates by distance/radio transmitter range.
I live in a large valley, and can drive around here forever (winter rims no TPMS) with no light. When I head out the highway, I get about 40km/25miles when the indicator light comes on. Time doesn't seem the issue to me, but the range of the TPMS transmitter.
My stockies are stored in the shed, at proper psi. Resets on its own whenever I get home.

 

I have heard about if you take them all out at the same time including the spare one it won't come on. You just need to get them away from the vehicle so they wont populate again. Also you need to make sure all of this is done without turning the key on. Let me know anyone who has heard of this..

 

Over the last 4 winter/spring seasons I have stored my winter tire package that has my original oem rims/sensors only triggering a light on occasion.
I can drive 20 miles away from the house, park all day or overnight & not trigger a light.
This past Sat. the seasonal swap was done.
On Sunday, I drove to NH & of course the light triggered.
Got home later in the day, parked overnight & the light had reset by itself when I went to work in the a.m.
There are few on here only using one set of sensors for winter/summer tire sets with the same results.

 

its timed. 20 minutes into your drive (away from the sensors) the light will flash for one minute. Then it will stay on. If you turn the truck off before the light begins to flash, this timer will be reset.
I went through this all winter long when i had my winter tires on and the summers were in the shed.

 

This ^^^^. Specifically, as stated in the FSM, a DTC (Diagnostic Trouble Code) is output when no signals received for 30 minutes or more, vehicle speed of 5 mph (8 km/h) or more detected and still no signals received for 12 minutes or more.

If you park where your tires with the registered TPM sensors are stored, the system thinks all is well until you are about 30 minutes into your trip. The system then checks for the registered sensors. If any fail to signal, the system rechecks after another 12 minutes and then fires a DTC if no signal is received. When you return to the registered tires location, the system again recognizes the sensors and all is well again.

 

Ah Ok. I drive 5 miles to work and 5 home where the oem's are, so that explains that. Was going to call the tire shop and see if they did something to keep the light from coming on. Thanks
