Are there any GM Tech’s on here? Trying to diagnose my 07 2.4. The code is P0335 (crankshaft circuit) plus I am also getting an exhaust camshaft code. I initially thought it was a bad crankshaft sensor but I see now that it is sending a signal after finding the “CKP Active Counter”. What should the counts be vs the camshaft’s “CMP Active Counter”? In a properly timed engine it should be a set ratio, correct? Counts seem way too low on the Crankshaft side. Also shouldn’t both camshaft counts be about the same? It almost but doesn’t start.
I am attaching an image of the tech2 ignition data with the CKP & CMP active counters.
