When a sensor drifts or fails you get a check-engine light, hard starting, poor power, smoke, or a drop into limp mode. A direct-fit replacement built to OE performance restores an accurate signal so the ECM can control the engine correctly again, clearing the fault at its source instead of masking it.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\u003cli\u003ea direct-fit replacement diesel sensor built to OE performance\u003c\/li\u003e\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eFits Chevrolet, GMC trucks equipped with the LLY Duramax diesel engine, 2004-2005.
