The sensor you pulled out looks different ( thicker barrel shaped) than the one pictured in the new part. Was it different shaped? Did it make a difference?

BEST ANSWER: The part fit perfectly on my explorer. I had trouble plugging in sensor (under hood) but only because small rubber bushing was stuck from old connection. Other than that no problems.
