The oil pressure gauge on the dashboard of my vehicle keeps going up and down randomly. At idle the pressure reads very low. I've done a recent oil change thinking it would solve the issue. The car sounds like it is running fine, however, at normal driving speed the dial drops to zero and the oil light comes on. It does it randomly, sometimes it'll do it after 20 minutes of driving. Sometimes it won't do it at all. Can this be a sensor issue? or maybe a hose issue?

It could be the oil pressure sender, or the oil pan is filled with gunk and needs to be cleaned out. here is the location of the oil pressure sensor so you can check it out and I have left the instructions on how to remove the oil pan in case you need it. (F106) If the sensor doesn't help change the oil and filter after you remove the oil pan and clean the oil pump pickup.
