This fault code is stored in the Engine Control Module (ECM) when the output from the camshaft position sensor is not as expected. The camshaft position sensor is used to monitor the position of the camshaft. The engine control module uses this information to determine the synchronisation and phasing of the camshaft in relation to the crankshaft. A fault in the variable valve timing and/or valve lift system will generate this fault code.
