The downstream heated oxygen sensor threads into the exhaust pipe behind the catalytic converter.

1. After removing the sensor, the exhaust manifold threads must be cleaned with an 18 mm X 1.5 + 6E tap. If reusing the original sensor, coat the sensor threads with an anti-seize compound such as Loctite(R) 771-64 or equivalent. New sensors have compound on the threads and do not require an additional coating. Tighten the sensor to 41 Nm (30 ft. lbs.).

2. Install sensor using an oxygen sensor crow foot wrench such as Snap-On tool YA8875 or equivalent.

3. Connect sensor electrical harness to clips along body.

4. Connect electrical connector to sensor.
