I have a 2001 that has a bad tire sensor in the right rear that constantly says it has 50 lbs of air. I read on the forum that you can reset them using a moderately powerful magnet. I tried and couldn't get it to reset so I'm thinking bad battery or bad sensor. My question is, does this have to be done at a GM dealer or would a reputable tire dealer or local mechanic be an option.

 

A tire shop should be able to do it for you. Buy the sensor from one of the forum vendors and have a tire shop install it and you will a lot of $$$.

 

It's very simple. Once you get the bead broken, it's just a matter of unscrewing the nut, replacing the sensor, and screwing the nut back in place, so don't let anyone tell you it's a big deal.

 

Hmm...I always thought that when the battery is dead in the sensor, they won't display anything. Did you do this:

1) Turn ignition on.

2) Press "Reset" button in order to clear any IPC display warning messages.

3) Press and release the "Options" button on the DIC to scroll through the display options until the IPC display is blank.

4) Press and hold the DIC "Reset" button for 3 seconds.

5) Press the "Options" button again until TIRE TRAINING message appears.

6) Press "Reset" button until the IPC "Learn L Front Tire" message appears in order to begin the programming.

7) Install the J41760 Tire Pressure Monitor (TPM) System Programming Tool (large magnet will do) over the left front valve stem.

8) The horn will sound, indicating the left front TPM sensor is programmed (if this takes more than 15 seconds, pull magnet back and try again, it will give you three tries. Then you must start over).

9) When the horn sounds, proceed to program the next TPM sensor in the following order as directed by the IPC messages: -Learn R Front Tire -Learn R Rear Tire -Learn L Rear Tire Programming can be canceled by turning ignition off, waiting 2 minutes with no sensors being learned, finishing all 4 wheels or through the DIC. If the programming is canceled with less than 4 sensors learned, it will only accept the codes programmed up to that point.

 

low/dead battery means a low or no pressure reading.
I assume you used a good manual tire pressure gauge and confirmed it was the TPS was reading erroneously?

Your magnet may not have been strong enough.
So if you are asking about a reset.... dealer.
If you are asking about replacement... any tire shop...

BUT bring your own new sensor or you will pay 2-3x for it....

The only other issue is the torque for the nut...
I had to bring my own torque wrench and socket.

Don't forget, you car has to be moving AFTER you reset, for TPS to start reporting pressure!
