5. Repair Instructions:
The intake VVT actuator assembly is only replaced as as assembly. Do not repair its disassembled components. For VVT actuator
replacement, refer to 2.6.8.12 Camshaft
2.2.7.14 DTC P0016
1. DTC Descriptor:
DTC
Engine Control Module (ECM) uses crankshaft position sensor (CKP) and camshaft position sensor (CMP) pulse signals to monitor
the correlation between crankshaft position and camshaft position. Crankshaft variable reluctance rotor has 60 teeth, of which two
missing teeth were used as a reference gap. Each tooth spaces 6° evenly, except the reference gap with a 12° interval. Camshaft
signal plate has 4 teeth, 2 narrow teeth and 2 wide ones. Each tooth trailing edge evenly spaces at 90°.

Control System JL4G18-D
(a) Connect scan tool to datalink connector.
(b) Turn the ignition switch to "ON" position.
(c) Press scan tool power button.

Are there DTC codes?
No
Conditions For Setting The DTC
(Control Strategy)
1. When camshaft and crankshaft
angle difference is greater than
20°, the DTC code is set. When
the angle is greater than 25°, the
camshaft and the crankshaft
adaptive is activated.
2. The camshaft and crankshaft
angle difference is greater than
the negative 25°.
