The system is supposed to compensate for barometric pressure from an input from the Manifold absolute/barometric pressure sensor, that signals this manifold and barometric pressure to the powertrain control module. Algorithms are written to compensate for altitude changes. </div></BLOCKQUOTE>
I follow what you are trying to say with regard to engine control, but I don't know how that relates to Tire Pressure Monitoring. The actual pressure inside the tire changes, which is what the system should monitor. It doesn't matter if the tire is at sea level or 15,000 feet - too much pressure is too much pressure.
