DTC DETECTION CONDITIONS AND TROUBLE AREA REFERENCE

DTC No.	DTC Detection Conditions	Trouble Areas
P0011 P0021	Advanced cam timing: With warm engine and engine speed of between 500 rpm and 4,000 rpm, all conditions (a), (b) and (c) met (1 trip detection logic) Difference between target and actual intake valve timings more than 5°CA (Crankshaft Angle) for 4.5 seconds Current intake valve timing fixed (timing changes less than 5°CA in 5 seconds) Variations in VVT controller timing more than 19°CA of maximum delayed timing (malfunction in advance timing)	Valve timing Oil control valve (OCV) OCV filter Camshaft timing gear assembly ECM
P0012 P0022	Retarded cam timing: With warm engine and engine speed of between 500 rpm and 4,000 rpm, all conditions (a), (b) and (c) met (2 trip detection logic) Difference between target and actual intake valve timings more than 5°CA (Crankshaft Angle) for 4.5 seconds Current intake valve timing fixed (timing changes less than 5°CA in 5 seconds) Variations in VVT controller timing 19°CA or less of maximum delayed timing (malfunction in retarded timing)
