Okay, bad news, sorta.

The Crankshaft Position Sensor (CPS) uses a 10VDC reference voltage to produce its signal, so is no way you can test it in car unless you have the tools to test for signals through the wiring insulation.

And its nearly the same for the MAP sensor as well except it uses a 5Vdc voltage reference.

The Camshaft Position Sensor also uses a 10Vdc voltage reference and interestingly enough, it shares that reference voltage with the CPS. Whats odd to me is that it is a 10vdc reference and Im not sure how they get it down to 10v, unless thats the minimum voltage need which in my experience is not typically the case, it usually states what it uses, not the minimums.

As a sidebar not related specifically to your issue, if that may not be the reason why those things fail so often. They use 10v as a reference but the electrical system when the engine is running is typically around 13.6v give or take a few tenths and if one were to use a voltage booster which would push that over 14vdc, meaning a 40% increase, that would push most electronics to the brink.

Okay, that said, both the crankshaft and camshaft position sensor go DIRECTLY to the Ignition Control Module. They are connected no where else. The ICM then uses those signal to output signals to the PCM such as the Camshaft position signal (obviously), timing signal, timing control and a couple others.

It looks to me that the 10vdc voltage reference comes from the underhood fuse block through a 15Amp fuse which appears to also provide the DC voltage to the primary side of the ignition coils.

So all that to say this. It leads me to wonder if you dont have a blown fuse anywhere, though I think you said you checked those (may warrant physically pulling and checking any fuse related to the ignition system, especially if its a 15amp fuse) or if there may be an issue with your ignition control module.

Now the good news in all this is that you can pull your ignition control module and take it some place like Autozone and they can test it for you. I think they can even test your ignition coils as well, which they can probably test it better anyway. You can check the resistance all day long on those things and it may be fine, but once they get warmed up they can open up, so that may be worth looking into.
