In the past, if Tank gets around 4,000 miles on an oil change, the CEL will come on for the oil pressure being low, and shows the code 0520 upon performing the key dance. This literally, is nothing new. However...a couple of weeks ago now, the light came on when leaving walmart. Turned around, bought stuff for an oil change and handled business. I reset the CEL by pulling the appropriate fuses, as I've done times before. The next day, the light came on while driving home from work. Mind you, I used the same type oil, oil filter, the whole nine yards...but now the CEL haunts me. I again pull the same 0520 code. I add another quart of oil today, reset the light, and then the light comes back on when I started the car to leave work. There is no performace issues, smells, or obvious issues I can sense other than the annoying light.
HELP!
