Is your Duramax going into limp mode, struggling with regen cycles, or throwing exhaust temperature codes? The Walker Exhaust Gas Temperature (EGT) Sensor restores the critical heat data your engine and emissions system rely on to function properly. This sensor monitors exhaust temperatures in real time and sends that information to your ECM, which can control fuel delivery, turbo performance, and regeneration cycles. When it fails, your truck can experience reduced power, poor fuel economy, and constant regen issues. Replacing it with a Walker sensor restores consistent performance, proper emissions operation, and reliable power whether you're towing or daily driving.

Built to survive extreme exhaust conditions, the Walker EGT sensor is constructed using high-temperature metals and ceramic components that maintain accuracy even under intense heat and pressure. Its rugged design resists failure caused by vibration, soot, and contamination from oil or coolant exposure, common causes of sensor issues. Engineered to meet OE specifications and manufactured under ISO-certified standards, each sensor is 100% tested to ensure precise readings, proper fitment, and long-lasting reliability in demanding diesel environments.
