my car is ticking like no oil but theres oil in it its full

no doesn't burn oil but it's very cold here that's when it started -20

oil pressure on dash gauge ok?

relay switch is bad been blinking for long time

My best guess is it should be ok as long as you have oil. Like i say ive seen these cars with ticking issues

how do I get it to go away?&what is a knock sender?
