P0452 Chrysler Code - EVAP Pressure Switch Stuck Closed
Quick Answer
When the EVAP pressure switch is stuck closed, it means that the switch that monitors the pressure in the evaporative emissions control system is not functioning properly. Common causes include Faulty Pressure Switch: The most common cause of this code is a faulty EVAP pressure switch that is stuck closed and unable to detect pressure changes in the system, Wiring Issues: Damaged or corroded wiring connections to the pressure switch can also trigger this code, Vacuum Leaks: Any vacuum leaks in the EVAP system can disrupt the pressure readings and lead to the switch being stuck closed. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P0452 Chrysler Description
When the EVAP pressure switch is stuck closed, it means that the switch that monitors the pressure in the evaporative emissions control system is not functioning properly. The EVAP system is responsible for capturing and storing fuel vapors before they can escape into the atmosphere. The pressure switch plays a crucial role in detecting any abnormalities in the system's pressure levels. When the switch is stuck closed, it can disrupt the proper functioning of the EVAP system, leading to potential emissions issues and affecting the vehicle's performance.

Po452 is only code I have on my 07 dodge Durango. My vehicle jumps idle some and just started dying at an idle. What do I change?
-
There must be something else. The P0452 code is for the Evaporative Emission System (EVAP) Pressure sensor and that shouldn't cause any engine performance problems.
Check for fuel pressure or dirty Air Flow sensor.
