Can a speedometer be miscalibrated to highway speed?
The calibration to highway speed is based on the recommended tire size for that wheel. In many vehicles the speedometer counts only integer rotations of the wheel, and is therefore unreliable for speeds below about 10 mph. It’s possible to miscalibrate the speedometer in several ways: for example, by putting incorrectly-sized tires on a car.
Can a bad speedometer sensor cause you to slow down?
A malfunctioning speedometer sensor can also cause a speedometer to act erratically, fluctuating the reading from one speed to another; even though in reality you’re not speeding up or slowing down.
What’s the speedometer reading on my Dodge Dakota?
I have a 2000 Dodge Dakota 4.7L. The speedometer is reading about twice the real speed. I went through a speed check (sing the reads out your speed on the side of the road) and it clocked me at 30 mph and my speedometer was reading 62 mph. The odometer is also adding miles at the same pace.

Where is the speedometer located on a car?
Where is the speedometer sensor located? The speedometer sensor is located in the transmission of your vehicle and is designed to register the driveshaft’s rotational speed. The sensor delivers this information through the speedometer cable and to the vehicle’s computer, which converts electrical pulses into a numerical speed.
How much accuracy do speedometers need to be accurate?
Until July 2006 this rule specified an accuracy of +/- 10 percent of the vehicle’s true speed when the vehicle was travelling above 40km/h. That is, at a true vehicle speed of 100km/h the speedo could indicate between 90km/h and 110km/h.
What should the Speedo read on a car?
The speedo must not indicate a speed less than the vehicle’s true speed or a speed greater than the vehicle’s true speed by an amount more than 10 percent plus 4 km/h. Odometer accuracy is no longer defined. What this means: For a vehicle travelling at a true speed of 100km/h, the speedo must read between 100km/h and 114km/h.
Can a speedometer read lower than the actual speed?
However, there is a limit as to how high or low a speedometer is allowed to read. Speedometers are not allowed to read lower than the actual speed of the car, but they are permitted to indicate a value that is 10% higher than the actual speed, plus 4.

When did the first electronic speedometer come out?
Mechanical speedometers have been around since the 1900s, whereas the automotive world didn’t see the first all-electronic speedometer until the late 1980s. Most modern vehicles use an electronic speedometer to gauge and display the speed of the vehicle.
