DTC P1336 will only set if PCM has not learned crankshaft position system variation. PCM only needs to learn this variation once per life cycle of vehicle unless CKP sensor-to-crankshaft relationship is disturbed. Removing a part for inspection and then reinstalling it is considered a disturbance. A fully warmed up engine is critical to learning variation correctly. If a valid learn occurs, no other learns can be completed that ignition cycle.

If engine cuts out before specified learn procedure engine speed or at normal fuel cut-off RPM, PCM is not in learn procedure mode. Review crankshaft position system variation learning procedure and re-enable learn procedure. See TOOTH ERROR CORRECTION LEARN PROCEDURE under POWERTRAIN CONTROL MODULE. Verify that scan tool indicates TEST IN PROGRESS.
