LS XR4145 Tractor Repair: Crankshaft Sensor Replacement Made Easy

This is a full hands-on repair walkthrough for an LS XR4145 throwing a P0371 crank sensor code, not a generic overview. It covers diagnosing with a scope, pulling the starter for access, swapping the sensor and O-ring, noting a thicker redesigned sensor tab, and clearing codes with an aftermarket OBD2 scanner, then confirming the fix by running the engine. Best for owners chasing an intermittent miss or limp-mode fault on this model.
