The spare is always to blame on those deals in my experience.

The spare is always to blame on those deals in my experience. No, it's the spare being gone. The sensor in the spare can't tell the receiver in the car how much pressure it has if someone steals the spare, now can it? (in the OP's case) |

My spare is till there, but the light is on....
I'm wondering if it is because the spare is low. I have put it in the shop twice and the say it is my aftermarket tires even though it didn't come on for the first 10,000 miles |

I spoke in generalities, its not looking for a tire, but a wheel, usually with a tire connected to it.

I hope it fixes your problem as well, if the spare is good then it must be some sort of glitch in the system, like I assumed in the first place. Back in the old days we used to have to actually look at the tires to see if they looked low and then use a gauge to verify

Usually the spare does not have a sensor in it. The system only reads pressures of the tires on the ground, 4 tires, not 5. What type of vehicle?

The ones I looked at turned on with centrifugal force used to engage the contact to turn on the sensor. The wheels have to be turning for the transmitter to be on. The new prototype batteryless one I looked at was on all of the time (no power switch) but it had to be spinning to create power.z |

$ 355 later I will have a replacement with the sensor and the light off next week
I hope the one they took blows on them and they die a fiery death (with no one else hurt)

Find someone you know who works in the Walmart Tire shop, they have a computer and manual to check your TPMS senors, sometimes they go bad and stop sending out a signal, you need this handheld computer to hold near the valve stem of the tire, or in Fords case 180 degrees from the valve stem. anyway they can be reset if needed. Usually, you have low air in one of your tires, usually it's got a slow leak, which trips your sensor, you can air up your tires and usually the sensor will reset itself. Some models will tell you which tire it is, however if you've had your tires rotated and they senors weren't reset, (relearned) they may show the wrong tire, cause your sensor thinks it's still in the drivers front, but it's been moved to the drivers rear but doens't know it. Anyway I don't know what walmart charges anymore, but I went through this a while back and they were pretty resonable, compare to everywhere else. fyi.

Pretty much every make and model of tire has some percentage of blow outs. It is a predictable event and if you are designing a vehicle, you should be aware that it will happen at some point. (it should be on the DFMEA) The question becomes what happens next with your design? You can try to reduce severity, detectability, or probability, or some combination of them. |

TPMS systems came about because the majority of the driving public are either too stupid or just plain too lazy to monitor the air pressure in their tires.
the reason for "best" air pressure is fuel economy...which is what 99% of all systems on cars are about...emission control and fuel economy. |
