tpms sensor

[torqdork]

When experimenting with tire pressures at track days (lowering in 2 psi increments from 34 psi), the TPMS dash light first illuminated @ 28 psi.

Question: On other Toyota and Lexus vehicles I've owned there was a button somewhere on the dash or glove box area that you could press once desired pressures were set even if those were outside factory spec to establish a new baseline pressure. Does FR-S have one? I hope so, my RE-11A's perform best @ 28 psi and I'd like to set that as the new reference without having to go to the dealership. They might not agree to do it anyway fearing potential liability. I checked the Owner's Manual and searched here but couldn't find an answer. TIA.

I think the only way to set the base pressure is through techstream. You can get cheap copies on ebay, or go to the dealership.

Well now..... I have a question to be answered. If I get a set of summer wheels with TPMS sensors installed and I get the sensors programmed into my car by the dealer will my stock wheels' sensors still work when I swap the wheel sets out for the winter or will I have to get the sensors of the stock wheels reprogrammed into my car?

Second question: If I get a set of summer wheels with out TPMS sensors installed is there a way for me to disable the system so that the light doesn't keep coming on? It seems that it has been mentioned on this thread that the system can be disabled, but no instructions have been offered as to how to do so.

Id like to know, too

1 square piece of black electrical tape, clears that right up

+2 on the tape method. I actually pulled out the instrument cluster and taped between the gauge overlay and the led for the TPMS.

SCREW TPMS systems!

The short answer is that the ECU needs to be changed each time the sensors change.

If you get a second set of wheels with sensors, (which I have done), you can buy a device called the ATEQ Quickset (see Amazon) which will store both sets of TPMS ID codes. Once set up with those codes on your PC, when you change tires, you connect it to the Diagnostic port and push a single button (either summer or winter) and it sets the ECU in the car for the correct codes for those wheels. You can then swap back and forth with that single button push from there in w/o connecting the device to a PC again.

Depending on where you buy your new sensors they may have to be initialized (turned on) which is a one time only thing that can be done by either the tire dealer, car dealer or there is a separate tool to do that.

If you second set has no sensors, I am not aware of a method to disable the light. It was mentioned earlier, but there was no detail, and I am not sure it can be done for this car.

we need someone to take tpms sensors out of tires and leave in trunk just for shits and giggles and share results

When I exchanged the tpms sensors into my new wheels(in trunk) and drove home with the stock ones(without sensors), I didn't see any lights come on...Not sure if you have to wait a couple days with them off for the light to come on? Anyway new wheels went on same day so I didn't drive around much without the sensors.

When I bought my new tire/wheel combo I researched the TPMS thing extensively. To my knowledge there is no fix other than swapping the sensors to the wheels, or buying another set and then reprogramming each time you swap summer to winter for example.

I distinctively remember reading of someone who tried the pressurized canister with the sensors in the trunk thing. It didn't work. Answer being they also have a motion sensor of some sort in them.

My tape job worked for me. I only ever think about in now when I turn on my high beams. I accidentally covered a small portion of the high beam icon with the tape.

They would have/will trip after traveling about 50 miles.

I put my stockies on my husbands tc….his tire light is on still too….lmao. Stupid sensors piss me off so bad. 1 more light on the christmas tree.

I also feel the sissy/nanny lights should be on when you start car and turn off when you turn them off…but that's another thread for another time.

not needed if you are good about checking your tires. you can blame firestone and their explorer tire blowouts that cause a mandate for tpms sensors. wells thats how i remember it.
