No speedometer can be 100 percent accurate. In fact, most manufacturers build speedometers so they fall within a fairly narrow tolerance range, no more than 1 percent to 5 percent too slow or too fast. As long as a car is maintained at factory specs, its speedometer should continue to register vehicle speed within this range.
Where is the speed sensor located?
The vehicle speed sensor, or VSS, is located near the transmission’s output shaft. The specific placement of the sensor allows the sensor to detect, and report, to the engine’s computer through attachment cabling, the rotation and speed of the shaft.
What is a transmission input speed sensor?
