Walker 273-10452 Exhaust Gas Temperature (EGT) Sensor

OE Base Exhaust Gas Temperature Sensor

Walker 273-10452 is an OE Base Sensor exhaust gas temperature sensor for gasoline and diesel emission systems. It provides the ECM with accurate exhaust temperature data to manage regeneration events and protect aftertreatment components in vehicles such as Nissan Armada, TITAN, TITAN XD, Frontier, and INFINITI QX80.

Key Features

• OE Base Sensor design for factory-style exhaust temperature monitoring
• Black connector with a rectangular 2-terminal, 2-wire layout
• Male connector with female terminals for direct-fit electrical connection
• Built for high-temperature and corrosion-prone exhaust environments
• Supports DPF regeneration in diesel applications and GPF regeneration in gasoline applications
• Engineered to meet or exceed OE requirements for resistance, response time, and signal stability

Product Details

Walker Products OE Base Sensor line focuses on replacement sensors built to match original equipment performance targets. Part number 273-10452 is an Exhaust Gas Temperature (EGT) Sensor that monitors exhaust heat so the ECM can manage aftertreatment functions, including DPF regeneration on diesel models and GPF temperature control on modern gasoline engines. This sensor is used on applications including 2017-2022 Nissan Armada, 2017-2022 Nissan TITAN, 2016-2022 Nissan TITAN XD, and 2016-2019 INFINITI QX80, making it a direct-fit option for common Nissan and INFINITI emission control repairs. This part cross-references Nissan 22630EZ30A for the same application.

Common Problems This Sensor Can Address

• Fault codes related to exhaust gas temperature readings
• Improper DPF regeneration timing on diesel vehicles
• GPF temperature monitoring issues on gasoline engines
• Aftertreatment system protection concerns from inaccurate exhaust data
• Signal instability caused by heat and corrosion exposure

Installation Notes and Tips

Verify connector shape, terminal count, and wire count before installation. Confirm the vehicle build date on 2021 Nissan NV2500, 2021 Nissan NV3500, and 2020 INFINITI QX80, since the listed fitment includes date-specific coverage. Inspect the harness and exhaust routing for heat damage before replacing the sensor, and clear diagnostic trouble codes after installation.

Quality Assurance

Walker builds this OE Base Sensor to meet or exceed original equipment specifications for resistance, response time, and long-term signal stability. High-temperature and corrosion-resistant materials are used to withstand exhaust system conditions in both gasoline and diesel applications.
