Buick GL8 / Old Buick LaCrosse 3.0L Crankshaft Position Sensor HOP 12598209 Direct Replacement

When your Buick Lacrosse or LaCrosse (Luxe) 3.0L has starting difficulties, engine stuttering, weak acceleration, or even stalls, the crankshaft position sensor may be aging or failing. This sensor monitors crankshaft speed and position and transmits signals to the ECU to control ignition and fuel injection timing. A fault will cause the engine not to run properly. This product is a HOP brand direct replacement, OEM number 12598209, specifically for Buick Lacrosse 3.0L and LaCrosse 3.0L models. During installation, ensure proper clearance between the sensor and the crankshaft reluctor and tighten bolts to the standard torque to avoid signal errors.
