No TPMS sensors no warning light!!!

[Sangria6MT]

I purchased winter rims and tires from Tirerac. To save money, I opted not to buy the sensors and just deal with the warning message\light. To my surprise, I'm not getting warnings or messages. Maybe Santa trough in a set sensors from Tirerack OR the system is not enabled in car? either way I'm happy.

It takes time and/or miles. It might go a week if you only do short drives, but rest assured, you will get the warning light soon enough.

Thanks for the info, But does that mean when my sensors are installed, it may take a week to warn me about a slow leak like.. if there was a nail in my tire? or is the absence of sensors different then a signal sent from one for low PSI.?

Totally different.

The computer knows the difference between not receiving a signal and receiving a signal that says the pressure is low.

I have a different type of question: I got winter rims on without TPMS sensor, so the warning light lit on as expected. However today I found it went off. WTH?

Did you park it near the regular tires (and sensors)?

Still off after 400 miles, original rims and tires stored in crawl space under house.

Yes but it's said that the sensor will send signal only when the tire spins? Besides, the warning light was on for a few weeks besides those sensors...

What is up with this TPMS stuff?

 

I, too, have a similar situation. I put on my new winter tires and wheels with TPMS from Tire Rack, and there is no warning light. EVERYTHING I have read, including the TireRack info and the saleman, says that you need the Ford triggering tool to train the sensors. But I have no light. I have driven 180 miles this way. (Longest trip was maybe 40 miles.)

 

I have not trained the sensors.

 

To prove to myself that the sensors were in there, I lowered the pressure on one tire to 20 psi and immediately got a "low tire pressure" warning. Filled it back up and the warning went away. At least I know that they work.

 

I am parked close to the old tires. And I can move them to the basement if I have to.

 

I will do some more driving, but it seems like a 40 mile trip would be enough. What is the point of buying the triggering tool?
