P0017Powertrain
Crankshaft/camshaft position correlation (bank 1, exhaust)
Where to start
The crankshaft and the exhaust camshaft do not line up. The same conversation as P0016: oil and sensors first, but with a chain rattle from cold you should not keep driving.
A code is not a diagnosis. It says which check failed, not which part to replace. Clearing it without repair only means the car will report it again in a few trips.

How the app helps
CarScan reads this code from your car through an OBD-II adapter, shows whether it is active now or only stored, names the module that reported it, and puts it into a plain-text report for your mechanic.
