Oil sensor
 

Can someone please tell me where this is located and maybe a picture?

its the only sensor on the bottom of the oil pan. Three 5mm allen bolts hold it in

is this the same thing as the oil level sensor?

something that goes bad or should i attempt cleaning it?

Oil level sensor yes, And they go bad. if your going to take it out you just replace it cause you have to drain the oil. Cleaning won't do anything

Oil pressure sensor is on the oil filter housing. If you have oil pressure warning (red light) the sensor most likely isn't the problem. Sludge is

No red light, just every 4 days or so the warning light pops up on the main display. Goes away in 3-5 minutes of driving

Check for connections or just scan it.
