I have a 2010 (bought in September of '09) Outback 2.5i Premium with 51,xxx miles on it. Yesterday, I made the 45 mile drive into work without any problems. The car sat for 10 or 11 hours and when I went to leave, I had the following warning lights:
- Check Engine - steady
- Vehicle Dynamics Control - steady
- Cruise - flashing
- Brake (parking) - flashing
I checked all my fluids - no problems. Visually checked the engine bay and the undercarriage - no problems. So, I made the 45 mile drive back to town where my hotel is. I stopped at Autozone and had a scan done. It kicked back:
P0026 - Intake Control Valve Solenoid Circuit, Range/Performance Bank 1
Possible Causes: open or short circuit, poor electrical connection, faulty intake valve control solenoid.
Well, I couldn't do anything with it at this point (7pm already, nearest dealer was another hour away). So, after eating dinner I went through the engine bay and disconnected and reconnected almost every wiring harness I could find. I started the car up, it also happened to be the third cycle after the warning lights came on, and everything cleared. No problems today going to or returning from work, so who knows.
Also, I recently had the ECM re-flash to update the emissions control system. I have noticed a slightly rougher idle, but it is also intermittent. I have heard of some other people having the same issue: brought in for cat recall... new code found (P0028?)
Now, this is partly for my education and illustration for everyone else. Here is what I think the intake valve control solenoids are:
There are two, one mounted at the front of the driver side of the piston block and one mounted at the rear of the passenger side.
So, if anybody has any opinions, corrections, more information please feel free to share!
