PLATE 9G5853 - Caterpillar

The Engine Control Module (ECM) detects the following conditions:
The ECM is not attempting to activate the intake valve actuation pressure solenoid and the ECM detects less than 25 µA for at least eight seconds.
The intake valve actuation pressure solenoid is off.Note: The ECM continually applies a small current to the intake valve actuation pressure solenoid. If a voltage source that is greater than 1.3 VDC is applied to the system, the current will fall below the trip point.System Response:The ECM will log the diagnostic code and the ECM will trigger a snapshot. The check engine lamp will illuminate once this diagnostic code has been active for more than ten hours.Possible Performance Effect:NoneTest Step 1. Perform the following diagnostic procedure: "Intake Valve Actuation System Oil Pressure Circuit - Test"Results:
OK - STOP
