Myshorts -that's exactly what they did. Took out the innards -which (not being very knowledgeable on the subject) I understand to be the motorized solenoid. Funny, but well before any of this was done or had even been thought about, I just out of curiosity pulled the plug on it one day and got the same result CBP stated. It had been 'buzzing' a little -when it should have been quiet. I was surprised to see it didn't seem to make any difference to the engine -and no check light either. But I didn't give it any further thought and just reconnected it. Coincidence that it would be exactly what the Kia techs pulled apart when I brought it in for a final check after the other shop did the unrelated motorwork.
