Looking for cam / crank waveform known good
Looking for a known good cam/ crank waveform for a 2008 Equinox 3.6 VIN 7. Inherited from another shop that swears timing chain is timed correctly. Trying to confirm reluctor did not move on crank .
I have attached waveform of both intake and B1 exh with crank.( First 2 pics) I only have 4 channels so I will upload both exhaust , B1 intake and crank shortly ( Last 3 Pics)
The codes that you are giving are telling you there is a timing issue. There is a tsb on the crank reluctor moving .
I seen that , trying to compare to known good waveform to confirm. This is AWD so only option to inspect crank is to remove Transfer case or oil pan
Here is a known good. diag.net/file/f1hmddq49…
