Question about 2004 Chrysler Pacifica
I had the oil changed as it was right at the 3000 miles to do so. It still is flashing but only periodically not every time that I drive the car. I also have codes 0440,0442,0456 reporting all say it is gas cap or evap system. I have replaced the cap as purchased from dealer. It is not the problem. Do believe there is more to it.
You have two problems going on.
The oil light is telling you the engine oil pressure is low. If the oil level is full, the sending unit for the light is faulty, or you actually do have low oil pressure.
The codes are for a leak in the EVAP system which could be the gas cap but could also be a number of other things. There are valves and hoses that could leak.
The engine oil pressure would need to be checked with a mechanical gauge, and the gas tank venting system would need to be tested for leaks.

Could be the gas cap. Do you fill the tank with the engine running?
Otherwise, check the hoses near the Evap canister. I have 2003 T&C and had the small leak and large leak codes. I looked at the evap cansiter and the hose coming from the fuel tank vapor line had a huge crack in it, to the point it had fallen off the evap caniser. I trimmed the end of the hose and reconnected and voila, no codes.
The evap canister is on the driver's side of the van, underneath, slightly behind the drivers seat.
BTW, to clear the codes without an OBDII reader, remove the negative cable for 5-10 minutes (15 to be safe). The computer resets and clears the codes, except for one that it sets saying loss of power to the memory.

SOURCE: Perform Service Light comes on
This is a setting that can be reset to 2000 miles - when it counts down to 0 you get the "Perform Service" alert. I believe if you use the Step function you will see "XX miles to Service" Use the reset button to set this back to 2000.

It is for an oil change mainly and any other service your maintenance manual suggests at the mileage interval. It needs to be reset after each oil change to be accurate.

Most likely it means that the mechanic didn't bother to reset the service interval after changing the oil.
You can do this yourself by hitting the Step button until you see 0 miles until Service displayed, then hold the reset button until it changes to 3000 miles.
