Hello everyone,

I have a 2006 Ford Mustang GT and I am having trouble with a CEL, code P0453 (EVAP System Pressure Sensor/Switch Circuit High). I have already replaced the Fuel Rail Injection Pressure Sensor because I read that might be an issue, but no luck. Now I am considering replacing Evaporative Emissions System Pressure Sensor. Although, I am slightly at a loss. If it is reading high then it must mean it is working, I tested the voltage on it and it is getting the correct voltage...

CEL Issue - Insight needed
