Just started this since your oil change? DIfferent viscosity? wrong filter?
SOURCE: Check engine light after oil change
If it is the service engine light, go to Auto Zone and they will put a scanner on it for free and diagnose the code. I may have fixed the same problem with my daughter's 2004 Dodge Stratus 2.7L V-6 a few months ago. Is it the "Oil Pressure Light" or the service engine light? My daughter's car had a sporadic low oil pressure light. Checking the actual oil pressure is more work, so I guessed it was the Oil Pressure sending unit and it was. When I took it off it the electrical connection was soaked in oil due to some internal failure. I put a new oil pressure sending unit on and the oil pressure light has not come back on.
If you remove the wire connector and there is no oil on anything, try sparying it with electrical parts cleaner and putting it back together. If the oil light is still on you will need to replace the sending unit.
It is an easy job, but it must be done from the underside of the engine in a tight space. Make sure the enginer is cool because the sending unit is close to the exhaust. There is an aluminum heat shield with three (3) bolts that needs to be removed and is most of the work. You will need to plug the hole with a clean rag or wait for the next oil change to do the job and replace it after you drain the oil.
If the easy steps above do not solve the problem then you may have bigger trouble like a bad oil pump, or worse yet, a really worn out engine that needs a rebuild.
Just last week, I has a SEL scanned at Auto Zone and it turned out to be the Engine Coolant Temperatuere Sensor. I removed the electrical connection and sprayed it with electric parts cleaner and put it back together. No light since then. Good Luck!

i have a 2003 dodge neon and mine does the same thing and i had the oil changed by the dealer, its full of oil as well, they put just a tad over in it and the light comes on and blinks for second then goes off and the only thing i do is let the oil go out on its own and get to the level its supose to be and once it gets to that it will stop, well it should but if you want to be sure have it checked out. i hope this helps you out, let me know if it does.
SOURCE: Changed oil in transmission and filters now won't go into gear
I Fixed it !!! What happened was that the "O" ring that came with the filter wasn't fully seated in the pump before i put the filter on. It was kind of hard to get it to seat properly I had to get a hammer and a socket w/ an extention and tap it in. It wont go in with finger pressure alone. To find out if this is what the proble is then take off the pan and remove the filter, if the "O" ring is attached to the filter when u remove it then this is the problem.

sounds like you have a bad connection to the oil pressure sending unit or the sending unit itself is bad. look for a loose connection and if it's ok just replace the sending unit.
