Where is the oil sending unit on 2007 dodge caliber?
The oil pressure sending unit on a 2007 Dodge Caliber is located on the engine block, near the oil filter. It's a small, usually one-wire sensor. You'll likely need to get under the car to see it clearly. A picture or diagram specific to your engine (2.0L or 2.4L) would be helpful for precise location, but that general area is the best place to start searching.
