Product Introduction
The Odometer Sensor 21.3847 / 2112-3706040 is a vehicle speed sensor developed for LADA 110, 111, and 112 series vehicles. It provides speed information by detecting transmission rotation and converting it into electrical signals for the vehicle instrument cluster and electronic systems.
Designed for replacement and maintenance applications, this sensor helps restore normal speedometer and odometer functions on older LADA vehicle platforms.
Application Background
Many LADA 110 series vehicles remain active in aftermarket repair markets. Over long-term operation, the original speed sensor may experience signal instability caused by aging components, mechanical wear, or electrical connection problems.
The 21.3847 replacement sensor provides a practical solution for maintaining accurate vehicle speed measurement.
Function Description
The sensor continuously monitors transmission movement during driving. According to rotation speed changes, it generates corresponding electronic signals that allow the vehicle system to calculate:
Vehicle driving speed
Travel distance
Odometer information
Dashboard display data
Reliable signal transmission helps ensure smooth communication between mechanical components and electronic systems.
