A couple weeks ago my dart fell on its face on take off right after getting gas. Misfired half a dozen times after that and then was fine and has been fine. Today it threw a cel for p0452 and died in a drive through fired back up took
Off backfired once and died when I stopped again. I had to give the car gas to get it to start. Then tonight it was fine again but the cel is still on. Does anyone have any ideas? I couldn’t find much about this code with this car in particular. It’s a evap pressure sensor code.

My understanding is the #1 reason for an evap check engine code is the gas cap.
It can be the cap itself or simply not tightened correctly after a fill up.

This did happen on my folks perfect 1998 Accord LX 4 banger. A new gas cap, like $4, did the trick.
I cleared the code and 1,000 miles later all is good.

The only other time I dealt with an evap code was in my 2001 Tundra; there was a cracked hose to one of the components.
Super easy fix.

It sounds like your error code is pointing to a sensor, so your solution could easily be different.
Good luck.

Poor running and low evap pressure (P0452) sounds like a vacuum leak to me...

Just a guess but I would say your canister purge solenoid is stuck open. Do you hear a hiss noise from the fuel fill hole if you unscrew the gas cap while the car is running?

Does the evaporation system connect to the vacuum system on that car?

On my old 318i, any slight leak - breather hose, oil filler cap, dipstick, etc., would cause a major air leak and the car would barely run if at all, and needed a lot of throttle to keep it going. An inadvertently disconnected breather hose from the intake trunk taught me that...

Gas cap is obvious, but this seems more severe. Did the pump overfill? Maybe something got logged with excess fuel?

P0452 DODGE Possible Causes
Faulty Evaporative Emission System (EVAP) Pressure sensor
EVAP purge hose/tube obstruction
Evaporative Emission System (EVAP) Pressure sensor harness is open or shorted
Evaporative Emission System (EVAP) Pressure sensor circuit poor electrical connection.

Any idea where the pressure sensor is?

The purge solenoid is usually directly connected to the intake manifold

If the solenoid is stuck open it will pull a constant vacuum on the entire evaporate emission system, including the fuel tank. The first thing the ecm usually picks up on are incorrect data from the pressure sensor

If I am not mistaking it is on fuel tank
I do know Dodge has reprogrammed PCM for this code on other vehicles.

Dont fill it up all the way, keep it a gallon or two from the top. Run a few tanks like that . 3rd tankful, fill it up all the way and if it stalls and sputters, its the evap pressure sensor.

Both times it has acted it up was right after we filled it up ironically enough.

They did fix the engine stalling on left hand turns though with the advent of fuel injection.
