if you unplug it, one of two things will happen. The engine stalls, or it runs better if not the same. If it stalls, the sensor is good. If it runs the same or better, double check your wiring and then return it. If you got a reman- it has a 1yr warranty, if new, Lifetime Warranty. Double check if its in stock first though. Most stores will order it in ahead of time if you let them know you are going to return it that way you have a lot less down time since it typically takes at least 2 days and ordering it tomorrow would mean you get it Tuesday at the soonest.
