Is your Duramax going into limp mode, throwing EGT codes, or losing power under load? The Walker Exhaust Gas Temperature (EGT) Sensor restores the critical temperature data your engine needs to protect itself and run efficiently. This sensor monitors exhaust heat levels and sends real-time feedback to your ECM, allowing it to adjust fuel delivery, turbo performance, and regeneration cycles. When it fails, your truck can experience reduced power, poor fuel economy, and even forced derates. Replacing it with this direct-fit solution restores consistent performance, proper regen, and the confidence to tow, haul, or drive hard without unexpected interruptions.

Built to survive extreme exhaust conditions, the Walker EGT Sensor is manufactured using high-temperature metals and ceramic components that maintain accuracy even under intense heat and pressure. Its rugged design resists damage from vibration, soot, and contaminants such as oil or coolant, which are common causes of sensor failure. Engineered to meet OE specifications and backed by ISO-certified manufacturing standards, this sensor is 100% tested to ensure precise readings, proper fit, and long-lasting reliability in demanding diesel environments.
