What do I do if the OBD (On Board Diagnostic) Scanner displays a P1336 (Crankshaft position (CKP) system variation not learned) code.
This re-learn procedure can be done by any GM Holden dealer via their Tech II programmer. For engine conversions the dealer may require donor vehicle original V.I.N. (Vehicle Identification Number) for dealer to gain access. This only applies to Holden Vehicles Manufactured in Australia.
This diagnostic code will disable the misfire monitor, and not warn the driver that the engine has entered a dangerous misfire event, which can cause catalyst damage & higher than usual emission readings.
This code should not effect the overall vehicle operation, and should not disable engine in any way.
