I just had new tires and rims installed on my 04 Coupe. The tire installer did not calibrate the sensors to the tire positions and the procedure is not in the owners manual. Does anyone know the procedure? Greatly appreciate the help.

just did it --the tire man has to have the gun to recalibrate the new sensors --or u will keep getting the alert

You can program the sensors yourself. Probably can find a strong enough magnet to work at your local hardware store.

From the 2000 Shop Manual: (My words)
-----------------------------------------------------------------

Programming TPM Sensors Tool Required:

J 41760 Tire Pressure Monitor (TPM) Programming Tool. (AKA: Strong magnet)

Important: Make sure the vehicle has been stationary for at least 2 minutes before attempting to program the TPM sensors.

1. Turn the ignition to ON.
2. Press the 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 the TIRE TRAINING message appears.

Notice: If the TIRE TRAINING message cannot be displayed, and the IPC is functioning properly, check if the BCM is configured with the correct RPO codes. Refer to BCM Programming/RPO Configuration in Body Control Systems.

6. Press the RESET button until the IPC LEARN L FRONT TIRE message appears in order to begin the programming sequence.
7. Install the J 41760 Tire Pressure Programming Tool (magnet)over the left front valve stem.
8. The horn will sound, indicating the left front TPM sensor is programmed.

Notice: If the horn does not sound after 15 seconds, remove then reinstall the TPM sensor programming tool. This procedure may have to be attempted up to three times in some instances.

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 Cancellation

1. The programming mode will be cancelled if any of the following conditions are met:

The program mode is exited through the DIC.

The ignition is turned to OFF.

All four sensors have been programmed.

The TPM system has been in the program mode for longer than 2 minutes
and no sensors have been learned.

2. If the program mode is cancelled with less than four codes stored,
the receiver will only accept the codes programmed up to that point.
