CAMSHAFT POSITION "A" - TIMING OVER-ADVANCED/TIMING OVER-RETARDED

DTC No.	DTC Detection Condition	Trouble Area
P0011 P0021	Advanced cam timing: After engine is warmed up and engine speed is at 400 to 4,000 rpm, condition (a) or (b) continues (1 trip detection logic): Valve timing does not change from current valve timing Current valve timing is fixed (difference between "target" and "actual" camshaft timing is more than 5° CA for 4.5 seconds and camshaft timing change is less than 5° CA for 5 seconds)	Oil Control Valve (OCV) Valve timing OCV filter Camshaft timing tube assembly ECM
P0012 P0022	Retarded cam timing: After engine is warmed up and engine speed is at 400 to 4,000 rpm, condition (a) or (b) continues (2 trip detection logic): Valve timing does not change from current valve timing Current valve timing is fixed (difference between "target" and "actual" camshaft timing is more than 5° CA for 4.5 seconds and camshaft timing change is less than 5° CA for 5 seconds)	OCV Valve timing OCV filter Camshaft timing tube assembly ECM
