I'm getting P0016 error which is related to cam position.
I tried a different cam pos sensor, no change. Checking wiring at the Cam position sensor itself. I found this diagram for wiring to it.
But when I check voltage at the connector (key on, not running) that goes into the cam position sensor, I get this:
I tried different ECMs, one production '09 CTS-V E67 & the other GMPP E67, with same results.
The 14mV thew me off, .014 volts? And why dont I see +12v on it?
