Can the car odometer be reset to zero?

Car odometer can be reset to zero. Below is the relevant introduction about car odometer: Principle: The odometer sensor measures the wheel's rotation speed based on the principle of measuring rotational speed. According to the wheel's diameter, each measurement cycle corresponds to one full rotation of the wheel, and the traveled distance is calculated by accumulating the number of rotation cycles. Purpose: The odometer sensor is located on the differential or half-shaft, generally using Hall effect or photoelectric methods to detect signals. Its purpose is to effectively analyze and determine the car's driving speed and mileage by counting the odometer readings, because the angular velocity of the half-shaft and the wheel is equal. Given the tire's radius, the mileage parameters can be directly calculated.
I often encounter this question when helping friends with car issues. The car's odometer typically cannot be reset. Its design prevents tampering, as most countries' laws prohibit altering odometer data to prevent fraud in used car transactions. Manufacturers install specialized chips in the dashboard to lock the odometer and prevent unauthorized changes. Even if you attempt to manipulate it with certain tools, it's illegal and may damage the instrument cluster. However, many car models have a trip odometer function, which can be reset for short-term fuel consumption or trip recording, making it quite practical. Therefore, unless under special circumstances, avoid tampering with the odometer—it helps maintain the vehicle's value and authenticity.
