Walker 273-10444 Exhaust Gas Temperature (EGT) Sensor - Rear

Walker OE Base EGT Sensor 273-10444

Walker 273-10444 is an OE Base Exhaust Gas Temperature (EGT) sensor for exhaust temperature monitoring in gasoline and diesel applications. It provides the ECM with temperature data needed to manage aftertreatment operation, including DPF regeneration on diesel systems and GPF regeneration on modern gasoline systems.

The OE Base Sensor line from Walker focuses on direct-fit replacement coverage with resistance, response time, and signal stability aligned to OE specifications. This sensor uses a black female connector, oblong connector shape, 2-wire layout, and 2 male spade terminals for a factory-style electrical connection.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emissions system monitoring
• OE Base Sensor line built for OE-style fit and signal performance
• Black female connector with oblong shape
• 2-wire design with 2 male spade terminals
• High-temperature, corrosion-resistant construction for exhaust environments
• Supports temperature feedback for DPF and GPF regeneration strategies

Application Details

Compatible with 2020-2022 Jeep Wrangler, rear, OE Base Sensor, and 2020-2022 Ram 1500, location before catalytic converter, OE Base Sensor. Walker 273-10444 is used where the ECM needs accurate exhaust temperature input to manage regeneration cycles and protect emissions components. This part number, 273-10444, is also referenced for the same application as an OE-style replacement sensor.

What It Helps Address

• Faulty exhaust temperature readings
• DPF regeneration concerns on diesel systems
• GPF temperature monitoring issues on gasoline systems
• Emissions warning lights related to EGT sensor performance
• Thermal stress on turbocharger and aftertreatment components

Installation Notes

Verify connector style, terminal layout, and sensor position before installation. Match the rear location on Jeep Wrangler applications and the before-catalytic-converter location on Ram 1500 applications. Inspect the harness and exhaust bung area for heat damage, corrosion, or contamination that could affect sensor readings. Confirm the replacement part number 273-10444 against the original sensor before service.

Quality Assurance

Walker builds this OE Base EGT sensor to meet or exceed OE specifications for resistance, response time, and long-term signal stability. The sensor uses materials selected for high exhaust heat and corrosion resistance to support consistent emissions-system operation.
