2004 dodge dakota check engine light on. How do i fix it?

Question

my 2004 dodge Dakota check engine light came on recently. after reading it returned fault code p0452. I have also noticed that it has been idling up and down, and stalling when coming to a stop. what do I need to do to fix the problem? any help would be appreciated.

Answer 1

P0452 NLVD Pressure switch stuck closed

With the RPM ideling up and down , this is most by false air entering into the engine interrupting the fuel / air balance. The EVAP purge solenoid if it is stuck open will also set P0452 and may be the cause of the erratic idle condition ,
