The crankshaft position sensor (CKP sensor) on a Ford E250 with the 5.4L Triton engine is located on the
passenger side (right side) of the engine block, near the front of the engine. It's typically mounted close to the crankshaft pulley, but not directly on it. You'll likely find it near the oil filter, sometimes even tucked behind it. It's usually a single-wire sensor with a small connector.
However, the exact location can vary slightly depending on the year of the van. It's best to consult a repair manual specific to your E250's year and model for a precise diagram and location. A visual inspection using a diagram from a repair manual is highly recommended.
