Ok, so as the OP on this thread I can see that some either didn’t read or understand
my question or misread what I typed.
First I am not having a problem, I was asking a technology operational question.
I believe I have the answer to what I was asking by gleaning out of the various
postings of those that understood my question.
The sensors are ID’d when learned into the car and being located LF-RF-RR-LR.
If a particular car can only indicate “A” tire pressure is low or “A Specific” tire is
low but regardless the car does NOT know if the tire has been moved to a different
If a sensor is assigned to LF and it stays on LF then and only then will the car
report the LF tire is low.
I realize that some reading this will say “who cares?” I just wanted to understand
that if someone tells me my car is smarter than another because it will know
the tires are in the wrong position if I do a tire rotation is not true.
It only helps with long term maintenance if after rotation that the sensors are properly
assigned and reset. Then it will be “somewhat” easier to determine which tire needs
air rather that walking around and checking all 4 tires to find the one that is low.
I also believe that these sensors are a technological PITA. They cost more and provide less than necessary benefits.
BTW this 07 Camry does not have a sensor in the spare!!
Also, what stated this was I had a low pressure reading and after trying to
figure out the problem it was determined that the LR had a bad sensor
and had to be replaced at a cost of $140.00 Doubt I will do that again!!
Will just let the Dash Indicator on and ignore it.
Thanks to those that have contributed to the thread.
