I've just discovered that the TPS on my '04 is reading the RF tire as the RR, and vice-versa. Is thts an easy fix done by changing a connection somewhere?

Simultaneously press the lock and unlock buttons on your key fob. The horn will chirp. Now hold a strong magnet by the LF tire valve until you hear another chirp, then do the same at the RF, RR and final the LR. Once completed at the LR you will hear two chirps. They are now in synch. You must do this every time they are rotated.

Thanks Ranger! Amazing technology! Tell me, does this "reprogramming" also have to be done if the battery is changed?

Geez-I can't believe I didn't know this had to be done after every rotation; I've had two rotations since I last reset the sensors.

:thepan: Ummmmm......... If a sensor is programmed to send "RF wheel", and that wheel is rotated to the LR, what does the sensor still send ??? :sneaky:

There's a good Japanese law firm in Baltimore - easy to find in the book - look for "SOSUMI". :rolleyes:

As it turns out the shop that did my last tire rotation must have also reset the sensors. I reset them last night and the same low pressure lf appears. This only lasts until the tires warm up then it shows the same pressure as the rest, except for about a pound. Sensor must be going.

Those things have a lithium battery installed. Of course, they have a finite lifespan. Anybody ever replace a battery, or do you have to replace the whole sensor ???

Don't forget that when the tires warm up you will pick up a couple pounds of pressure from heat expansion.

The battery is not a service item. It "might be" possible to replace the battery but GM only sells the complete sensor.

I had a sensor replaced a year ago. I believe it was less than $10, to my surprise. When I had my tires rotated, they must have reset the sensors without telling me, because the readings were still accurate. This was all at a service station, not a dealer.

You might check the service documents if you can; sensors were more like $40 to $50 last time I checked.

Do everything you can to be sure this 'service station' operator remains in business! You have found someone who cares about your car and your future service needs. Rare.
