This is a pattern of injector against MAP sensor. Where we can see when engine load increases it will increase injector open time. So with more RPM's injector must open more often and for a longer time. If MAP sensor not working properly it will create a miss fire and rich or lean burn in the engine, which cause high emission and bad fuel economy. Engine can have a flat spots in acceleration and perform not well.
RPM sensor and injector. Common thing in both of them is that they start to open and ignite spark plug faster
with increase of RPM's, so frequency increases. If injector not working properly or fuel pressure is low or high, it will make engine misfire or have a flat spots in acceleration. Same as spark plugs ignites at the wrong time they can cause detonation in the engine and damage it. 
Oxygen sensor and injector by making engine goes rich we make injector open more often and for longer. And in the same time oxygen sensor reads rich combustion.
Primary ignition and injector.All this test has been done on a Toyota Corolla 4AFE engine, and from this test we can see which component doesn't work properly by matching it against the other component pattern. When one of the component works with errors it can effect the others.
G1 is not primary ignition but the RPM sensor which sends a signal to the ECU which then triggers the primary coil, this is primary ignition
