Walker 273-10443 Exhaust Gas Temperature (EGT) Sensor - Front

Walker OE Base EGT Sensor 273-10443

Walker 273-10443 is an OE Base Exhaust Gas Temperature (EGT) sensor built for accurate exhaust temperature monitoring in gasoline and diesel engines. It supplies the ECM with the temperature data needed to manage aftertreatment operation, including DPF regeneration on diesel applications and GPF temperature control on modern gasoline systems.

Compatible With 2020-2022 Jeep Wrangler, front and 2020-2022 Ram 1500, front. The Walker OE Base Sensor line focuses on OE-style fit and signal performance for emissions-system service on vehicles that rely on precise exhaust temperature feedback.

Key Features

• OE Base Sensor design for direct exhaust temperature monitoring
• Black female connector with oblong shape
• 2-wire, 2-terminal configuration with spade terminals
• Built with high-temperature and corrosion-resistant materials
• Engineered for stable resistance and response time under exhaust heat
• Supports ECM control of DPF and GPF regeneration strategies

Product Details

Walker Products exhaust gas temperature sensors are designed to meet OE specifications for signal stability, response time, and durability in harsh exhaust environments. On diesel vehicles, the sensor helps the ECM manage DPF regeneration and protect related components such as turbochargers and SCR systems. On gasoline applications, it monitors GPF temperature so regeneration cycles can be controlled without thermal overload. Part number 273-10443 is a direct-fit emissions sensor solution for front-position applications on the Jeep Wrangler and Ram 1500 listed below.

This part cross-references no listed aftermarket part numbers for the same application.

Common Issues This Sensor Can Address

• Fault codes related to exhaust gas temperature signal loss or drift
• Improper DPF regeneration control on diesel applications
• Incorrect GPF temperature feedback on gasoline applications
• Emissions-system performance issues tied to inaccurate exhaust temperature data
• Thermal protection concerns for turbocharger, DPF, or SCR system operation

Installation Notes and Tips

Verify the connector style, terminal layout, and front-position fitment before installation. Inspect the exhaust harness and mating connector for heat damage, corrosion, or bent terminals, since sensor accuracy depends on a clean electrical connection. Confirm the replacement location matches the original sensor position on the vehicle.

Quality Assurance

Walker OE Base Sensor 273-10443 is built to meet or exceed OE specifications for resistance, response time, and long-term signal stability. The sensor uses materials selected for high exhaust temperatures and corrosion resistance to support reliable emissions-system operation.
