CDL Code Description Information
1901-5 Engine Intake Valve Actuator #1 : Current Below Normal The ECM monitors the current flow through the circuit for each actuator. If low current flow (open circuit) is detected, a -5 diagnostic code is activated. The ECM continues to try to activate the actuator. If high current flow (short circuit) is detected, a -6 diagnostic trouble code is activated. The ECM will disable the solenoid circuit in order to prevent damage from the high current flow. However, the ECM will periodically try to activate the actuator. If the short circuit remains, this sequence of events will be repeated until the problem is corrected.
The ECM takes the following actions while the code is active:
Engine power is derated by 10 percent.
The amber warning lamp is illuminated.
These codes are usually caused by a wiring problem. The wiring problem can be on the outside of the engine or underneath the valve cover.

1906-6 Engine Intake Valve Actuator #6 : Current Above Normal System Operation During Engine OperationThe intake valve actuation system does not operate until the engine has reached normal operating temperature. Also, the engine must meet certain operating conditions in order to activate the intake valve actuation system.There are three housings under the valve cover. Each housing contains two actuators. There is a solenoid for each actuator. The ECM sends a command to a solenoid when the ECM requires the intake valves for a cylinder to remain open. The ECM monitors the current flow through the circuit for the solenoid. The ECM activates a diagnostic code if the current flow is below normal or above normal.
