P1450 code 2014 ford escape?

If You see the p1450 error code it means that the pcm has detected an excessive vacuum in the fuel tank and/or the evap. This can be caused by a leak in the vacuum line. A vacuum leak on the car can be caused by a couple of things. The most common is the hose that is running in the system has been damaged. If the hose has a hole in it, or the hose has dry rotted, then it will leak. It is also common to see the connection points fail, meaning that the hose will leak where it connects to other devices. Finally is there is an issue with the intake manifold then You will find that the hose may leak from there. All of this will make it so the vehicle shakes and shuddered, both when idle and driving. This will put a strain on the engine, and may eventually cause it to fail. Replacing the hose is pretty simple, the trick is finding where the leak is coming from.
