Hi everyone.
I have a 2015 Taurus with 123,000 miles. Engine is running rough and there are 2 trouble codes.
P2196
P2198
It doesn't appear to be related to air intake.
Does anyone know of specific tests I can run in Forscan to pinpoint what might be causing the codes?
Thanks

2015 Taurus Limited P2196 & P2198
Re: 2015 Taurus Limited P2196 & P2198
I had some time this afternoon to work on the car. It looks like my assumption was correct. The issues were related to the Vapor Canister solenoid. It was stuck open causing irregularities with the engine vacuum. I replaced the valve and all seems to be well. Apparently this valve failing is a common occurence in Ford products 2009 and newer.
