I just replaced my bad sensor with one from the local Checker auto parts store and can verify that it does work. If you can solder and have a heat gun it will take an extra 20 minutes to do this, but you'll save at least $50 in the process. Tell the parts store you need a sensor for an 86 Ford Taurus V-6. Make sure it's a Bosch of course, which should be Bosch #13913. The thread and tip length are exactly the same as the stock sensor. The only difference is the connector. The Taurus one has about 5" of wire then a connector on it. Basically you'll remove the old sensor from the pipe, along with a metal track that supports the wires going up under the car (you'll see this track when you get under the car). Cut the old sensor out at the spot were the new sensor will match up, put heat shrink on each of the 3 wires and a larger piece of heat shrink on the whole splice, and voila, you have a $42 dollar replacement. Just make sure you pre-wind the sensor counterclockwise before you thread it in so that you don't twist up the wires when the sensor is fully threaded in. Let me know if you have any other questions.
