So many of us have the winter tires with no TPM module inside. We just ignore the yellow TPM light on the dash board. However, the indicator bulb may not last long if left on 5 months a year. Knowing how complicated is to replace a $1 bulb from my experience with my 1994 Camry (the whole dash instrument panel had to be disassembled to gain access to the bulb), I would like to find a way to turn this warning light off in the winter season (yeah, I mean OFF, not by putting a electrical tape over it). Is this possible?
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. Idea to fool the tire pressure sensors | Page 3 | PriusChat
Thank you very much. Somewhere in that post, someone did ask why don't we just pull out the whole TPM module. Do you have any idea why can't we do so?
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.
What do you mean by "solid state indicator"? LED bulb, filament light bulb, or something else? Both have limited life span if left on so best to extend its life to as long as possible.
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.
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.
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.
