How to get the TPM light turn off when winter tires have no TPM

I have no answer.

I have two sets of tires. One set for summer, and on set for winter. But only the summer tires have the pressure sensor.

How to get the warning light to go off? No idea. I wish I knew.

 

This works perfectly, I've used it on my 2010 and 2014... Follow his instructions, and if it doesn't work straight away, refer to his post #66.

Here's a pdf of those two posts, plus a third further along, that clarifies the jumper install:

 

Is there a separate TPMS module, or is the TPMS function simply part of a much larger module?

 

Was really hoping it was the thread which someone replied the fix with a photo w/a scissor next to a roll of electrical tape. The OP of the thread was unsure what the photo was about, I laughed my butt off.

 

Just use the tape. Its a solid state indicator anyway, its not going to burn out.

 

For the Prius and a Vibe I bought my snow tires at Costco and had them fit the new tires to the original wheels (with their original TPMS sensors). Then, when it came time to reinstall my summer tires, I bought identical Denso TPMS sensors on Amazon for approx. $40 each, and fairly basic wheels at my regional tire-service chain, and had them install the snow tires and the new TPMS sensors on the new wheels, and install the summer tires on the original wheels. I've done the switching back and forth of the wheels myself so far each season, and the tire store has always reset the TPMS system for me free of charge.

 

My TPMS indicator has been on for 3.5 years. 2 tires are missing the pressure monitors and I don't plan to add them. TPMS is generally a preventive measure to avoid blowouts, they are calibrated to alert at I believe 25% low from the recommended pressure. So assume 35 and it would alert at a tire pressure of around 27psi. Don't depend on them to tell you when you need air in your tires.
TPMS light on passes inspection in NC.

 

I pump tires up to 59 psi and set tpms to that value then deflate tires to 44 psi and drive. I depend on tpms to let me know to air up.

 

FWIW our TPMS light has been on for 10+ winters now, still on.

 

So if you have a slow puncture that is about to become a major blowout, you won't get a warning.

 

With the snow tires that's correct; there's no sensors. Once the all-seasons on OEM rims are swapped back on, the TPMS system is again operational.

 

Neither do anyone else who doesn't have system.
You can feel it how the car drives.

 

Mazda's TPMS sensors are automatically detected by the car, say when swapping to snows. Toyota, nope...

Ah, there is always a back story that people need to ask to understand. Love jumping in to conclusions myself.
