Is the timing mark correctly aligned ?
YES
▶ Substitute with a known - good CVVT and check for proper operation. If the problem is corrected, replace
CVVT and go to "Verification of Vehicle Repair" procedure.
NO
▶ Repair or replace as necessary and then, go to "Verification of Vehicle Repair" procedure.

GENERAL DESCRIPTION
E58BBD36
The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the intake camshaft. This
system controls the intake camshaft to provide the optimal valve timing for every driving condition. The ECM controls the
Oil Control Valve(OCV), based on the signals output from mass air flow, throttle position and engine coolant temperature.
The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV. As result, the relative posi-
tion between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves,
exhaust emissions decrease under overall driving conditions.
DTC DESCRIPTION
EB3171E9
Small particles in the engine oil may cause the oil control valve to bind or otherwise get stuck at certain spool positions.
A test is used in this diagnostic to detect a stuck valve spool. A cleaning function is then used to try and free the spool. If
unsuccessful, the diagnostic test is failed.
Figure 1. illustrates the principle of the valve stuck diagnostic test. As in the phaser error diagnostic illustration, there are
two cases shown in the figure. The case on the left shows a case where the dutycycle is above a calibration threshold,
yet the phaser position is near the minimum position. Under normal operation, such a duty cycle command would move
the phaser toward its maximum position.The case on the right shows the opposite situation. The duty cycle command is
below a threshold, yet the phaser position is near its maximum.

PCM monitors OCV stuck while cam offset is available and Valve cleaning is not in progress .If the PCM detects that CAM
position angle is over 20 CAD(Crank Angle Degree) than expected cam positionthat PCM controls the OCV while cam
position is in designated crank angle degree, PCM determines that a faultexists and a DTC is stored.
