Table 1
Diagnostic Trouble Codes for the Intake Valve Actuators
J1939 Code CDL Code Description Information
2950-5 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 ten 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.
