Figure 5 Graph 1: Air Management System Test (Good)
Graph Analysis:
This graph shows normal operation of the Air Management System (AMS) during the Air Management Test
(AMT). The AMT gives pass or fail results based on the difference of flow in MAF Mean Value (MMV). It allows
the user to validate the AMS by monitoring the effects each actuator has on Intake Manifold Pressure (IMP).
IMP is normally between 2 psi (14 kPa) to 6 psi (41 kPa)
