is mostly green indicating there is no problem with the vehicle in fig3 the ve chart and table are loaded this engine uses a manifold absolute pressure sensor instead of a maf sensor the ve table shows mostly green indicating the air flow into the engine is good in fig3 the simulated injector chart was then filled this chart fills with mostly green indicating there is no problem between the actual injection time and calculated injection time in fig3 the power chart was then loaded which indicates the engine made 80 horse power which shows there is no power loss with this engine the sequencing of tests in the automated test routine is set forth in fig3 a j during the automated test a rationality check is also performed in this testing sequence all of the pids are taken into account and compared against one another one basic example of the rationality check is if the engine is cold the engine coolant temperature and the intake air temperature would need to be within 5 u00b0 f within one another if the difference in temperature is greater than 5 u00b0 f then one of the sensors is not operating correctly a more complicated example is that the vehicle 39 s.
