Vacuum switching valve
My wife has taken the Avalon in for oil changes and this has happened twice. After getting the car home I always check that they put in the proper fill of oil and check that her battery wasn't stolen as this happened before. Each of the last 2 times I checked under the hood I found that the cable going to the Vacuum switching valve was disconnected.
Can this harm anything if left off? Why would anyone disconnect this cable just for an oil change? |

Re: Vacuum switching valve
If this is disconnected it will set a code P0446. There is no reason to disconnect during oil change. Considering your history (assuming this is the same store) it is time to find an honest shop???
