Walker 273-10445 Exhaust Gas Temperature (EGT) Sensor - Rear
Walker OE Base EGT Sensor for Emissions Control
Walker OE Base Sensor 273-10445 is an Exhaust Gas Temperature (EGT) sensor built for accurate exhaust temperature monitoring in gasoline and diesel applications. It provides the ECM with the temperature data needed to manage aftertreatment operation, including DPF regeneration on diesel systems and GPF regeneration on modern gasoline systems.
Compatible With 2019-2021 Chevrolet Colorado, 2020-2021 Chevrolet Express 2500, 2020-2021 Chevrolet Express 3500, 2019-2021 GMC Canyon, 2020-2021 GMC Savana 2500, and 2020-2021 GMC Savana 3500 in the rear position.
Key Features
- OE Base Sensor line built to match original equipment fit and signal requirements
- Gray connector with oblong female housing
- 2-wire design with 2 terminals
- Spade terminal type with male terminals
- High-temperature and corrosion-resistant construction for exhaust service
- Supports exhaust temperature monitoring for diesel and gasoline aftertreatment systems
Product Details
Walker 273-10445 is engineered to meet or exceed OE specifications for resistance, response time, and long-term signal stability. In diesel applications, the sensor helps the ECM manage DPF regeneration and protect turbocharger and SCR system components. In gasoline applications, it monitors GPF temperature so regeneration cycles can be controlled and thermal overload reduced. This Walker OE Base Sensor line is focused on direct replacement performance for emissions system service on Chevrolet Colorado, GMC Canyon, and related Chevrolet Express and GMC Savana platforms.
This part cross-references no listed aftermarket part numbers in the provided data.
Common Issues This Sensor Can Address
- Fault codes related to exhaust gas temperature sensor performance
- Incorrect DPF regeneration control on diesel vehicles
- GPF temperature monitoring faults on gasoline vehicles
- Emissions system warning lights tied to exhaust temperature readings
- Signal instability from heat- or corrosion-damaged sensors
Installation Notes and Tips
Verify the connector shape, color, terminal type, and wire count before installation. Confirm rear sensor placement and match the OE Base Sensor application to the vehicle’s emissions system layout. Inspect the harness and connector for heat damage, corrosion, or bent terminals before connecting the new sensor.
Quality Assurance
Walker builds this sensor to OE-based specifications for resistance, response time, and signal stability, using materials selected for high exhaust temperatures and corrosion resistance. That design focus supports consistent exhaust temperature measurement in demanding emissions-control service.
