Walker OE Base EGT Sensor for Ram Diesel Applications

Walker 273-10470 is an OE Base Exhaust Gas Temperature (EGT) sensor built for accurate exhaust temperature monitoring in modern gasoline and diesel emissions systems. It provides the ECM with the temperature data needed to manage aftertreatment functions, including DPF and GPF regeneration, while helping protect exhaust components from heat-related damage.

Compatible With 2019-2022 Ram 3500 and 2019-2022 Ram 2500 applications, this sensor is built for direct replacement use in after-catalytic-converter and before-catalytic-converter locations where specified. The Walker OE Base Sensor line focuses on OE-style fit, signal stability, and durable construction for demanding exhaust environments.

Key Features

  • Part number 273-10470 exhaust gas temperature sensor for emissions control systems
  • OE Base Sensor line engineered to meet or exceed OE resistance, response time, and signal stability targets
  • Supports DPF regeneration in diesel applications and GPF temperature monitoring in gasoline applications
  • High-temperature, corrosion-resistant construction for harsh exhaust conditions
  • Black connector, oblong connector shape, 2-wire design
  • Male connector with female terminals and 2 terminal positions

Detailed Description

Walker Products 273-10470 is an exhaust gas temperature sensor designed to deliver accurate exhaust temperature feedback to the engine control module. In Ram 2500 and Ram 3500 applications, that data helps the vehicle manage regeneration cycles, maintain emissions system performance, and protect components such as the DPF, turbocharger, and SCR system where equipped. The OE Base Sensor line is built for consistent operation in high-heat exhaust streams and for stable electrical signaling over long service life.

This sensor is a direct-fit style replacement for specific Ram 2500 and Ram 3500 locations, including after-catalytic-converter and before-catalytic-converter positions listed in the fitment data. Walker 273-10470 is a practical choice when you need a replacement EGT sensor for Ram diesel emissions service and accurate exhaust temperature monitoring.

What It Helps Address

  • Check engine lights related to exhaust temperature sensor faults
  • Incorrect DPF regeneration timing or incomplete regeneration events
  • Faulty exhaust temperature readings sent to the ECM
  • Emissions system performance issues tied to EGT sensor signal loss
  • Heat management concerns in turbocharger and aftertreatment systems

Installation Notes and Tips

Verify the sensor location before installation, since fitment includes both before-catalytic-converter and after-catalytic-converter applications. Confirm connector style, wire count, and terminal configuration against the original sensor: black connector, oblong shape, 2-wire layout, male connector, and female terminals. For Ram 2500 and Ram 3500 service, match the vehicle year and exhaust position exactly to the fitment listing.

After installation, clear any stored diagnostic trouble codes and confirm the ECM reads exhaust temperature data correctly. This part number is 273-10470.

Quality Assurance

Walker Products builds OE Base sensors to OE-level specifications for resistance, response time, and long-term signal stability. The sensor uses high-temperature and corrosion-resistant materials to withstand exhaust-system conditions common in Ram emissions applications.
