Check oil level light displays after oil change and new air filter,level drops to 0,ideas?

Question

The vehicle had just been serviced when the issue started. No code displays. The oil pressure drops to zero when coming to a stop or slowing down. The gauge needle wavers while driving. There is plenty oil, as it was just changed. The check engine level light comes on, but no code.

Answer 1

did you use 5w-30 oil? the wrong oil weight can affect the oil pressure switch

what size engine do you have?

the V6 takes 4.5 quarts of oil and the V8 takes 6 quarts of oil. if you have the correct oil weight and correct amount I would change the oil pressure switch
