450,000 cars sold each year are victims of odometer fraud—taking a car odometer and rolling back the displayed mileage to increase the perceived value of the car. Odometer rollback is a federal offense, and modern cars make it very difficult to do, but according to pop culture, rolling back the mileage is as simple as driving in reverse. Yeah, the Motor MythBusters don't believe that for a second.

In the 1986 movie Ferris Bueller's Day Off, the titular role—played by Matthew Broderick—convinces his best friend to take his dad's pristine 1961 Ferrari GTO California Spyder on a day-long joyride while they ditch school. Obviously, daddy would notice the increase in mileage, but Ferris assures his friend they can simply put the Ferrari on jackstands and let it run in reverse for a while. You'll have to watch the movie (and this episode of Motor MythBusters) to find out if that worked.
Back in ye olden days, when a car odometer was an analog affair, the dial was turned by a cable connecting the odometer and transmission. That actually wasn't that long ago; most car manufacturers started phasing out mechanical odometers in favor of digital versions in the early 2000s.
Rolling back to how mechanical odometers actually functioned, the transmission output shaft of a car is equipped with a specially designed spline gear that drives the speedometer gear. Yes, we're talking about recorded distance, not speed, but it's all the same assembly.
Fun Fact: Two of the last cars sold in the United States with mechanical odometers were the 2003 Pontiac Grand Prix and the 2005 Ford Crown Victoria and Mercury Grand Marquis (Canadian-built models).
The speedometer gear spins a cable that is connected to a set of gears that turn a numbered dial that displays mileage using the mathematical magic of gear reduction. The rotating speed and diameter of the transmission output shaft spline gear, the diameter of the speedometer gear, and diameter of the car's drive tires all affect the odometer's output. This is why changing the diameter of a car's drive tires without changing the speedometer gear can affect the displayed speed and recorded miles.
It's easy to think that because there is a direct mechanical connection from the odometer gear set to the transmission output shaft, turning the transmission the opposite way would roll back the miles. Indeed that was the case until around the 1960s, when auto manufacturers started making more sophisticated odometers capable of recording distance traveled in both forward and reverse with ratcheting and free-wheeling gears like you find on a bicycle.
Modern digital odometers replace the clockwork and cables with magnetic sensors that record the number of times the transmission output shaft rotates. That information goes to the car's onboard computer, and after some electrons shoot through processors and wires, you've got all the information you need to operate your car.
Mechanical or digital, odometers can be changed if one tries hard enough. But the Motor MythBusters want to arm you with the knowledge of what to look for when a used car seems too good to be true. Sometimes, with mechanical odometers, it's as simple as checking to see if the numbers line up properly. Digital odometers that can be changed with professional-grade diagnostic tools and are more tricky to spot odometer fraud.
With either case, think of all the contact points you have inside a car: the driver's seat, steering wheel, pedals, sun visors, various switches and buttons—unless those are replaced or refurbished when the miles get rolled back, they will all display signs of wear commensurate with the actual mileage of the car.
People who are willing to commit odometer fraud to make easy money are probably not likely to put lots of effort into covering up these small but telltale signs of use.
The traction pad on the brake pedal in a car with less than 20,000 miles shouldn't be falling off or showing the metal underneath. Same for other high-wear areas like the seat bolsters or window switches. The steering wheel shouldn't be deteriorated or feel worn. Even fresh tires on a low-mileage car can be a clue that the odometer has been tampered with.
A low-mileage car shouldn't have many interior blemishes that can be associated with regular use. This is the opposite of the classic colloquialism, "never look a gift horse in the mouth." We say, "always look a used car in the pedal box," and the Motor MythBusters agree.

ATV speed sensor - a device responsible for collecting and transmitting information to the vehicle's ECU. The signals sent allow you to calculate the speed of the ATV. But what to do if you bought an ATV, and after a while you found a malfunction? In this case, you need to figure out how and when the speed sensor is replaced.
Obviously, if the sensor is broken, the ATV's speedometer will not display speed.
The instrument panel of the ATV will simply stop working or start to function incorrectly, showing false information. Although this is not the most serious problem that a rider may face.
Due to speed sensor failure:
In addition, if the ATV does not show the correct speed, problems with the odometer begin. For example, you can drive only 50 km, and the device will increase the mileage of the ATV by 300-400 km. A similar problem is especially unpleasant if you plan to sell the device, because a few tourist trips will increase its mileage by a couple of thousand kilometers.
If you notice on the speedometer that the ATV is not picking up speed, then you need to check the speed sensor. Of course, the speedometer itself could break, but this rarely happens.
The sensor may fail due to:
Before dismantling the speed sensor, it is advisable to carry out a basic diagnosis of the speedometer. It will be enough to check the condition of the wiring and cable, as well as clean its nodes from dirt.
It's worth noting right away that each ATV uses different types of sensors. Therefore, you should not buy a device “at random”, as you will simply throw money away. To select the appropriate component, you need to study the documentation of the ATV. Usually it specifies the specification of spare parts.
You can also dismantle the old device and take it to a specialist shop. However, remember that an unsuitable sensor cannot be fixed near the propeller shaft, and the data from it will be inaccurate.
Keep in mind that original spare parts for branded ATVs are expensive. And, to save money, you can take a similar Chinese sensor. For example, on the CFmoto X8 all-terrain vehicle, you can put a device with the number 35.3847, which is used in domestic cars.
If you notice that the ATV does not develop speed according to the speedometer or if you find other symptoms of a sensor malfunction, you need to replace the part.
Even a novice driver can do this. To perform the procedure, you need:
Actually, this is the end of the job. The rider can only check the operation of the device. If the sensor is functioning correctly, the speedometer will show that the speed of the ATV increases and decreases, the vehicle will stop stalling, and fuel consumption will decrease by 15-20%.
