It is necessary that MAPS should be checked along with TPS. Because the MAP/TPS rationality diagnostic is
comprised of two tests. A deceleration test is performed to provide a robust method for detection of an altitude
compensated MAP value that is too high for the deceleration condition. The second test compares the altitude
compensated MAP value to both high and low limits, dependent upon throttle position and engine speed. When the
MAP value is out of the threshold range, the MAP/TPS system is determined to be failed.
