Walker 273-10023 Exhaust Gas Temperature (EGT) Sensor

Walker 273-10023 Exhaust Gas Temperature Sensor

Walker 273-10023 is an exhaust gas temperature (EGT) sensor built for exhaust-mounted temperature monitoring on select Saab 9-3 applications. It uses a 2-wire, blade-terminal design with a black oval connector and a 14.0 thread diameter for a direct-fit style replacement where specified.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control systems
• Fits 2003 Saab 9-3 and 2003-2004 Saab 9-3, after catalyst
• Exhaust mount location with 14.0 thread diameter
• 2-wire design with 2 terminals and blade terminal type

This EGT sensor is listed for Saab 9-3 models in 2003 and 2003-2004 after the catalyst, making it a targeted replacement for exhaust temperature monitoring on those vehicles. If you are sourcing a Walker 273-10023 replacement for a Saab 9-3, verify connector style, thread size, and exhaust location before installation.

This part cross-references EGR449 and ETS10023 for the same application.

Common Issues This Sensor May Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings in the engine management system
• After-catalyst sensor signal problems on Saab 9-3 applications
• Connector or terminal mismatch during sensor replacement
• Emissions monitoring issues tied to a failed EGT sensor

Installation Notes and Tips

Confirm the vehicle is a 2003 Saab 9-3 or 2003-2004 Saab 9-3 with the after-catalyst sensor location before ordering. Match the 14.0 thread diameter, oval connector shape, and 2-wire configuration to the original part. Inspect the exhaust bung and wiring connector for heat damage, corrosion, or thread wear before installing Walker 273-10023.
