CYLINDER & SEAL GP-STICK 5656417 - Caterpillar

The Electronic Control Module (ECM) detects Engine Intake Valve Actuator #1 : Current Below NormalThe ECM will log the diagnostic code.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 will derate the engine power by 10 percent.
