Yeah, true. But, I don't know why it's so low in the first place.

For what it's worth...my new Echlin tested a somewhat sad .4 the day I instaled it. A few days later I saw .5 something, and last I checked it was around .65...Idk what to make of that. I suppose if I had a .2 from a new CPS, I'd try another meter...easily said there!

Ok, so I drilled out the top hole and I am still getting a reading of only .2 AC volts. Crappy aftermarket sensor?

Also, my meter reads fine. I tested the battery in my fiances car while running and was getting 13.8 volts.

Did you bypass the C101 with the CPS wires?

Not yet. I wanted to drill out the top hole and see what reading I got first. If the reading is low, bypassing the wires isn't going to help very much.

How so? If my meter is only picking up .2 AC volts, then the ECU is probably only getting like .05 AC volts.

Correct. Because the C101 is in between them......

Do y'all know if the CPS is interchangeable between the 6 and 4 cylinder engines? According to O'Reillys, they are the same part number.

Ok, so I bought a Mopar CPS and put that on, it still won't start. Next is ignition coil and ICM?
