Is your truck throwing EGT-related codes or losing efficiency because it can’t accurately monitor exhaust temps? The Walker Exhaust Gas Temperature Sensor restores precise temperature readings, enabling your ECM to properly manage fueling, turbo operation, and emissions systems. When an EGT sensor fails, it can lead to poor performance, excessive regen cycles, and even potential engine damage, but replacing it brings your Duramax back to running efficiently, cleanly, and reliably under all driving conditions.

Built to meet or exceed OEM standards, this sensor uses high-temperature metals and ceramic components that withstand extreme exhaust heat, vibration, and contamination. It’s engineered for OE-style fit and response, installs as a direct replacement, and is 100% tested to ensure accurate, consistent output over time. Designed for long service life in harsh diesel environments, it delivers dependable performance whether mounted before or after emissions components, such as the DPF or catalytic converter.
