P0452 evap pressure sensor circuit fault fixes?
I received this code and had two suggestions: either the sensor itself is faulty or their is an air leak. I want to check for any leaks first. Where, on a 2001 Bonneville, are the air hoses located? Are there any common locations on this model where leaks generally occur.
I currently have my SES light on. Thanks for any insight. This forum has been a great resource.
