2.2.7.14 DTC P0016
1. DTC Descriptor:
DTC
P0016
Unreasonable Camshaft and Crankshaft Relative Installation Position
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°.

The difference between
crankshaft and camshaft
synchronization learn value and
reference value
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°.
