Best Answer

1. Remove the 4 bolts securing the heat shield to the exhaust manifold, and lift away the heat shield for access to the sensor.

2. Trace the wiring from the sensor body back to its wiring plug and disconnect it. On models with two sensor, the second sensor is located in the exhaust pipe, under the oil pan. Not how the wiring is routed, as it must not come into contact with hot exhaust components.

3. Unscrew the sensor from its location, and remove it. Once removed, take great care that the sensor is not dropped or damaged. Kepp the sensor tip clean while it is removed.

4. Installation is reverse of removal.

Good luck, I copied this answer from Chilton's.
