Conditions Which Generate This Code:
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 ?A 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:
None
Perform the following diagnostic procedure: “Intake Valve Actuation System Oil Pressure Circuit – Test”
Results:
• OK – STOP.
