How to Change the Oxygen Sensor on a Ford Taurus
Depending on the year of the Ford Taurus, there may be two or more oxygen sensors present in the exhaust system. In the common 3.0-liter 6-cylinder models, there are four sensors. Read and diagnose the trouble code that set off the "check engine" light to ensure youre replacing the correct sensor.
Instructions
- 1
Drive the Taurus onto a car lift. Put on safety glasses and crawl underneath the car.
2Locate the sensor you need to replace. 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.
3Unplug the oxygen sensor from the wire harness.
4Remove 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.
5Apply a light coat of anti-seize lubricating compound to the threads of the new oxygen sensor. Be caul not to get any of the compound onto the head of the sensor.
6Thread the sensor into the porthole of the exhaust pipe. Tighten with the ratchet and oxygen sensor socket.
7Plug the oxygen sensor wire back into the wiring harness.
