Is your Duramax throwing EGT-related codes, struggling with regen cycles, or losing efficiency because it can’t accurately monitor exhaust temps? The Walker Exhaust Gas Temperature Sensor restores precise temperature readings to your ECM, enabling it to manage fueling, turbo behavior, and emissions systems properly. When a rear EGT sensor fails, especially after the DPF, it can lead to poor regen performance, reduced fuel economy, and drivability issues. Replacing it with this direct-fit sensor brings your truck back to running cleanly, efficiently, and consistently under all conditions.

Built to meet or exceed OEM specifications, this sensor uses high-quality metals and ceramic components designed to withstand extreme exhaust heat, vibration, and contamination. Engineered for precise response and long-term durability, it delivers stable, accurate readings even in harsh diesel environments. With an OE-style fit and connector, installation is quick and straightforward. Every unit is 100% tested to ensure reliable performance, helping your emissions system operate correctly, and your engine stay protected mile after mile.
