Tire pressure detection

I got a tire pressure warning, and one was down to 22 psi. It has a
slow leak, I now know. But after filling it and keeping it filled to
32, the warning never goes away.

Does it sense with a real pressure sensor, or by measuring rotation
since the ABS does that anyway?

Some cars use pressure sensors, some cars use tire rotation.

I should have included that this is a 2002 LeSabre.

Indirect monitor. Uses the same sensors as ABS.

Turn the ignition switch to RUN.

Press the GAGE INFO button on the Driver Information Center until "TIRE
PRESSURE" appears on the display.

Press and hold the DIC RESET button for about five seconds. After five
seconds, the display will show "TIRE PRESSURE RESET". If "TIRE PRESSURE
RESET" does not appear in the display after about five seconds repeat
the procedure. If it does not work after two tries, see Testing and
Inspection.
After you release the DIC RESET button, "TIRE PRESSURE NORMAL" will
appear in the display. The system completes the calibration process
during driving. Calibration time can take 45 to 90 minutes, depending on
your driving habits. After the system has been calibrated, the system
will alert the driver that a tire is low, up to a maximum speed of 65 mph.

Isn't that great. It's THAT easy! See how simple that was.

That depends what model car it is.

Thank you. Sorry to take so long.
