The waveform on the right shows the CKP waveform
even narrower, which indicates higher RPM. The
engine is running at +2000 RPM, full load condition
and the CVVT system is maximum advanced. There
are approximately 6.5 CKP waveforms from the CAM
waveform on the left. This time 6° each equals
40° advances.

CVVT DTC Hi-Scan Pro has an activation test for the OCV.
There are several new DTC that are related to the
CVVT system. Two unique DTCs are:
• Such as DTC P0010 Camshaft Position Actuator
Circuit when the camshaft mis-alignment exceed 5°
CA from the target position. This can be caused by
malfunction of the CVVT assembly due to
insufficient oil flow.
• DTC P0341 Camshaft Position Sensor Range
indicates that the camshaft position is mis-matched
with the crankshaft position when the CVVT is in
the fully retarded position and not operating. This
can be due to the timing belt or chain off timing or
incorrect CMP or CKP sensor signal.
