Depending on the year of the Ford Taurus, there may be two or bounteous O2 sensors indicate in the exhaust operation. In the universal 3.0-liter 6-cylinder models, there are four sensors. Scrutinize and diagnose the difficulty edict that originate the "proof engine" aglow to arrange you're replacing the prerrogative sensor.
Instructions
1. Coerce the Taurus onto a motorcar lift. Deposit on safety glasses and crawl underneath the vehivle.
Tighten with the ratchet and oxygen sensor socket.7. Plug the oxygen sensor wire back into the wiring harness.
Unplug the oxygen sensor from the wire harness.
4. Remove the oxygen sensor, using socket and ratchet. If necessary, heat up the pipe surrounding the oxygen sensor with a torch for easier extraction. Allow the pipe to cool down before continuing.
5. Apply a light coat of anti-seize lubricating compound to the threads of the new oxygen sensor. Be careful not to get any of the compound onto the head of the sensor.
6. Thread the sensor into the porthole of the exhaust pipe.2. Place the sensor you must to change. Two of them are screwed into each side of the Y-pipe coming off each manifold; there are two more downstream located after each catalytic converter.3.
