Part is #9 on this diagram. It's on the bottom corner of the oil pan so it's easily accessible. Just swap it out on your next oil change.

1. Remove oil pan bolt to drain oil and remove oil filter as per normal oil change.
2. Unplug the electrical connection to the sensor. Make sure you don't get any oil on it.
3. Remove the 3 hex nuts and pull out the old sensor.
4. Clean the area around the hole before you put the new sensor in. Make sure you use the new gasket that comes with the sensor.
5. Tighten the 3 hex nuts and reconnect the plug.
6. Install the new oil filter, replace oil pan bolt with new washer and refill with new oil to complete the oil change.
7. Take it for a short run and then check for leaks around the sensor.
