Our my 2006 Ford Fiesta WQ LX started exhibiting the same speedometer issue a few months ago, and it has progressively gotten worse. Basically, the speed on the speedometer will drop to zero intermittently (half the duration of the trip, started off being 10-20% of the trip). Apart from the speedometer not displaying the speed, there is no other issue/symptom.

Does anyone know the part number of the speed sensor?

My local mechanic said after diagnosing the issue, the speed sensor needs to be replaced. He contacted the local Ford dealer, and Ford wants $215 for the speed sensor without providing him with the part number!

So appreciate it if someone who has ordered the replacement speed sensor can provide the part number so I can buy online, instead of paying $200+ from Ford directly.
For the auto the speed sensor is 3N217J148AA.
