Disconnect the battery to prevent electrical shorts. Remove the old oxygen sensor carefully using an appropriate oxygen sensor socket. Verify the connector type matches the factory harness before installation. Thread the new sensor by hand initially to avoid cross-threading, then tighten to manufacturer torque specifications. Reconnect the wiring harness securely to the radiused polygon male connector. After installation, clear any diagnostic trouble codes and verify sensor operation with a scan tool.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eWalker Products Aftermarket oxygen sensors are manufactured to meet or exceed OEM specifications for fit, form, and function.
