DTC P0011: Long response time when receiving a signal to change the position of the intake valve shaft
Long response time when signaling the position of the intake camshaft (with phase
control)

DTC Category
Valve Timing Control Valve Lockout for Exhaust Valves
Short circuit in the charge air intercooler circuit to high voltage
P2603
Short circuit in a chain of the liquid pump on a high voltage
High voltage in the system
Does not light up
P0016
(b) Troubleshooting principle: The engine control unit determines that the camshaft phase change rate by the VVT system
is less than 10°/s, or that the phase change rate of the reverse phase shifter is less than 5°/s.

A
Short or open in fluid pump heater control circuit to low voltage
(d) Possible cause of the malfunction: the pressure in the fuel line is out of range.
