Intermittent CEL, P0026
Hey guys! My '05 Outback Sedan 3.0R keeps throwing a P0026 code (Intake valve control solenoid circuit range/performance bank 1)for, what seems like, no reason at all. The oil level is where is should be, there doesn't look like there are any oil leaks, and the sensors are all properly connected. Any suggestions on how to fix this? It's driving me nuts. Thanks.

It may be a bad or leaking pressure switch. Number 5 in the pic.

No. Take the air filter box out of the way, unplug it, remove, replace.

Incendio:
Further to cardoc's suggestions, check around the pressure switch for visible oil leakage, especially at the joint between the metal base and the plastic upper part, and at the connector at the top. Also, if you have a digital multi-meter, could you check the resistance of the switch between the terminal at the top and the metal base/engine block when the engine is off? I suspect that sometimes the codes (P0026 and P0028) experienced with the variable valve lift mechanisms might be related to deterioration of the contacts inside the switches but need data to confirm. See my thread: Variable Valve Lift oil pressure switch resistance |

30 Ohms is a lot higher than the 10 Ohms I observed. (Thanks for reporting in the other thread.)
Did you identify where the leak is coming from, and if the switch was replaced, did that resolve the problem? |
