Cylinder deactivation codes
Hey guys, new here but looks like a lot of knowledgeable folks here. Hopefully you can help me with my issue. I have a 2011 suburban with the 5.3. The issue is the girlfriend ram it to low on oil and now it’s running horrible. I hooked my scanner up to read the check engine codes and this is what I got.
P1400- scanner can’t identify code
P0300- Random/Multiple Cylinder MisfireDetected
P3401- Cylinder 1 Deactivation/Intake Valve Control Circuit/Open
P3425- Cylinder 4 Deactivation/Intake Valve Control Circuit/Open
P3441- Cylinder 6 Deactivation/Intake Valve Control Circuit/Open
P3449- Cylinder 7 Deactivation/Intake Valve Control Circuit/Open
i was thinking maybe the deactivation solenoid fried and to replace that. Any info or where I should even start would be appreciated. Thank you
