P0520 code / oil pressure switch.
hey guys! just changed my oil last week for the first time on my 06 5.7 with 69980km on it.donno what oil was in it but i presumed it was dealers since it had a mopar filter and i bought it at a dealer.so i put in mobil1 5w20 in it and a jobber filter witch is very common and use them on some of my customers cars with no problem! so same night i was preparing for a fishing trip i went for some last minute shopping and some gas.i was more on the gas then usual since i was in a hurry so when i left the gas station my check engine light came on code P0520 witch is oil pressure switch.
unpluged battery and made a couple stops on a 250km trip didnt came back on.an hour after arriving at the chalet had to go to the store came on as soon as the truck started.same thing on the way back 5 days later.then when back home went for gas it came on(stays on,i have to unplug the battery to make it go away)and at the gas station the oil light blinked twice inside of a minute.so today i changed the oil filter again in case i got a defect but still the same and the oil light comes on almost everytime i stop for more than 5 seconds.could it be that the oil pressure switch didnt like the oil change??
