Walker Products OE Line Details
The Walker Products OE line focuses on engine management and oxygen/air-fuel sensors developed for direct replacement use. Part number 250-241267 follows that approach with application-specific fitment for the Cadillac CT6, including Bank 1 Sensor 2 and Bank 2 Sensor 2 downstream locations listed in the fitment data.
What This Sensor Helps Address
- Check engine light related to oxygen sensor performance
- Poor engine operation caused by incorrect exhaust feedback
- Increased fuel consumption from inaccurate air-fuel monitoring
- Higher exhaust emissions from a failing downstream sensor
- Stored ECU fault codes tied to the affected sensor circuit
Installation Notes
Before replacement, inspect the sensor wiring harness and connector for damage, since physical wear can shorten sensor life and affect operation. Confirm the vehicle’s downstream left or downstream right position before ordering, and verify the fault code points to the correct sensor location. This part number, 250-241267, is listed for 2019 and 2020 Cadillac CT6 applications only.
Quality Assurance
Walker Products is an automotive ISO 9001/TS 16949 certified company with a long history in engine management components. The OE sensor line is manufactured for specific vehicle applications and diagnostic requirements.
