Tire Pressure Sensor..

What happens if you mix up which sensor was on which tire? Does it matter? can a RF be on a RB? or a RF be on a LR? And if it matters how can I tell which goes where?

 

it does matter. the system knows which sensor goes to which tire.

Hmm I don't think so. I've thrown all of my sensors in a pressurised tube, which I keep in the truck. No light has lit up yet and it's'been about 8 months now.

 

So what do I do now since they are mixed up?

 

hmm... thats true.

at least for programming the system, it knows which sensor goes to which tire. maybe after its programmed it doesnt matter?

 

no, i think the car's brain just reads 5 sensors in it proximity.

 

If the vehicle has a TPMS that indicates 'which' tire is low, it matters.
If the vehicle has a TPMS that only indicates that 'A' tire is low it doesn't matter.

If you have mixed up the sensors on a TPMS system that can alert you "which" tire is low.
You would need to have the dealer reprogram the sensors to the TPMS system.
Or you could let the air out of the tires one at a time to determine where the TPMS thinks that wheel belongs.

 

Don't think so either...it would be hell to rotate tires. You'd have to mount and dismount the tires if the TPMS were wheel or corner specific, if that was the case. Plus i'm sure shops don't label the wheels when they're putting on new tires. They just throw that shit on and go.

 

It does not matter, at least in my case. I just rotated my tires and no problem with the sensor. When my spare was low it just indicated a problem. Did not tell me which tire was low. Had to check them all until I found the tire with low pressure.

 

FTW, it doesnt matter. Discount tire broke two of my sensors and replaced them and moved tires and sensors around WITHOUT resetting any part of the system. It just makes sure all 5 sensors are in existence and working properly
