This front axle potentiometer sensor reports the angular position of the front axle to the tractor's electronic control unit. It is mounted on the axle assembly and provides a variable voltage signal that the control system uses to adjust steering response and implement functions. A failed or drifting sensor causes erratic steering behavior or fault codes related to axle position. The original component is manufactured to match the housing geometry and electrical connector layout of the assembly it replaces, so no adapter harness or bracket modification is needed.
