  1. Great video, can't wait for more :) i actually like the obd2 systems on modern cars.... Knowing how it works and what sensors it's using to calculate fueling demands or ignition timing really helps in diagnostics. When you don't understand these systems and JUST look at trouble codes you can get tossed into a world of circles and frustration when you have a code pointing to a part or system, but the part is only called out with a code because it's normal values have been put out of range by another issue.
