Locate the oxygen sensor in the exhaust manifold at the passenger-side rear of the engine, under the hood in the center lower engine area. Follow the wire from the sensor to its connector, typically within about 12 inches, and continue tracing it through the firewall or a wire loom if needed until the ECU connector is found.
