Walker 273-10442 Exhaust Gas Temperature (EGT) Sensor

Walker OE Base EGT Sensor for Infiniti

Walker 273-10442 is an OE Base Sensor exhaust gas temperature sensor built for accurate exhaust temperature monitoring in 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 excessive heat.

Compatible With 2016-2018 INFINITI Q50 and 2017-2018 INFINITI Q60, this Walker exhaust gas temperature sensor is built around OE-style electrical and connector details for direct replacement service. The Walker OE Base Sensor line focuses on factory-style fit and signal consistency for emissions control applications.

Key Features

• Part number 273-10442 exhaust gas temperature sensor for emissions control systems
• OE Base Sensor line for factory-style replacement fit and signal behavior
• Black connector with rectangular shape
• 2-wire, 2-terminal design with male connector and female terminals
• Built for exhaust temperature monitoring in gasoline and diesel applications
• Supports ECM control of DPF and GPF regeneration cycles
• Constructed with high-temperature and corrosion-resistant materials

Detailed Description

Walker 273-10442 is an exhaust gas temperature (EGT) sensor engineered to deliver stable temperature feedback in modern emissions systems. In diesel applications, it helps the ECM manage DPF regeneration and protect turbocharger and SCR components. In gasoline applications, it monitors GPF temperature so regeneration can be controlled without overheating the exhaust system. This sensor is a direct-fit style replacement for 2016-2018 INFINITI Q50 and 2017-2018 INFINITI Q60 applications that use the OE base sensor configuration.

This part cross-references Nissan/Infiniti OE numbers 226305CA0A and 226305CA0B for the same application. The 273-10442 part number is a practical match for buyers searching for an Infiniti Q50 exhaust gas temperature sensor or Infiniti Q60 EGT sensor replacement.

Common Issues This Sensor May Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect DPF or GPF regeneration control
• Exhaust temperature readings that are unstable or out of range
• Reduced emissions system efficiency from inaccurate ECM temperature input
• Heat-related stress on turbocharger, SCR, or filter components

Installation Notes and Tips

Verify connector shape, terminal count, and wire count against the original sensor before installation. Confirm the vehicle application by year, make, and model, then inspect the exhaust harness and connector for heat damage or corrosion before connecting the new sensor. After installation, clear any stored diagnostic trouble codes and confirm the ECM reads exhaust temperature data correctly.

Quality Assurance

Walker builds this OE Base Sensor to meet or exceed OE specifications for resistance, response time, and long-term signal stability. The sensor is designed for durability in extreme exhaust conditions and consistent operation in emissions control service.
