Walker 273-10451 Exhaust Gas Temperature (EGT) Sensor
Walker OE Base EGT Sensor 273-10451
Walker 273-10451 is an OE Base Exhaust Gas Temperature (EGT) sensor for gasoline and diesel exhaust systems. It monitors exhaust heat so the ECM can manage aftertreatment functions, including DPF regeneration on diesel applications and GPF temperature control on modern gasoline engines.
The OE Base Sensor line is built around factory-style fit, signal response, and long-term stability. This Walker exhaust gas temperature sensor uses a gray oblong female connector with 2 terminals, 2 wires, and spade-style male terminals for direct replacement service where the original sensor matches these specifications.
Key Features
- Exhaust Gas Temperature (EGT) sensor for emissions system monitoring
- OE Base Sensor construction for factory-style replacement fitment
- Gray oblong connector with female housing
- 2-wire, 2-terminal design with spade terminals
- Built with high-temperature and corrosion-resistant materials
- Supports exhaust temperature feedback for diesel and gasoline aftertreatment systems
Product Details
Walker Products 273-10451 measures exhaust temperature data and sends it to the ECM for precise emissions control. In diesel applications, that information helps manage DPF regeneration and protects downstream components such as turbochargers and SCR systems. In gasoline applications, it monitors GPF temperatures to help regulate regeneration cycles and maintain exhaust system integrity. This part cross-references OE-style numbers such as 55495857 and 55593638 for the same application.
Compatible With 2016-2021 Chevrolet Colorado, location before diesel particulate filter; 2016-2021 GMC Canyon, location before diesel particulate filter; 2017-2019 Chevrolet Express 2500, location before diesel particulate filter; 2017-2019 Chevrolet Express 3500, location before diesel particulate filter; 2017-2019 GMC Savana 2500, location before diesel particulate filter; and 2017-2019 GMC Savana 3500, location before diesel particulate filter. If you are searching for a Chevrolet Colorado EGT sensor 273-10451 or a GMC Canyon exhaust gas temperature sensor, this OE Base Sensor matches the listed applications.
Common Issues This Part Addresses
- Fault codes related to exhaust gas temperature sensor performance
- Incorrect DPF regeneration timing on diesel vehicles
- GPF temperature monitoring faults on gasoline applications
- Unstable or inaccurate exhaust temperature readings
- Emissions system warnings tied to sensor signal loss
Installation Notes
Verify connector shape, terminal style, and sensor location before installation. This part is listed for the before-DPF position on the covered diesel applications, so confirm the original sensor placement and harness match the gray oblong 2-wire connector design. For best results, inspect the exhaust bung, wiring, and nearby heat shielding during replacement.
Quality Assurance
Walker OE Base sensors are engineered to meet or exceed OE specifications for resistance, response time, and signal stability. The sensor body uses materials selected for high exhaust heat and corrosion exposure, supporting consistent operation in demanding emissions-control environments.
