It is my opinion that
the majority of electrical related problems are with the sensors. Since driving CWP's (cars with puters) I have YET to ever have the actual puter go out. It is usually either sensor problems or wiring. Including other vehicles over the past 10 years the only thing that took me awhile to troubleshoot was the "ignitor" and that was on a Mazda. I find the mechanical maintenance items kinda/sorta fun.
