Im having a speed sensor issue with my g35 coupe 2007 a/t while monitoring the car with my scanner it shows erratic vehicle speed, I’m unsure as to which sensor or sensors are in control of this speed, below is a picture where it shows my car going at “150 mph” when in reality I’m only going about 40 mph.

at first I thought it would be the internal speed sensor located in the transmission, but I am able to go into manual mode and also cruise control works, any help would be much appreciated.
