Review on Denso 234 9002 Fuel Ratio Sensor by Luis Despain

Just installed this sensor and it seems to be working. Will upgrade to 5 stars later if it keeps working. Used WD-40 and sprayed all three screws. Two sensor screws (12mm) and one (10mm) terminal screw. I waited 24 hours and all three screws came off easily. The electrical connection was a big problem. It is not possible to disassemble the connector using conventional means such as pliers and a screwdriver to pry open the terminal. The plug was mostly glued. The problem is that there is no obvious way to create a lever to separate the two parts. I finally found an easy way and please see the attached photo. You use a vise on the sensor side of the connector to create a hard leverage point so you can then use that point to pry open the connector with a screwdriver. The blade of the screwdriver goes between the edge of the vise and the front edge of the connector housing. Just make sure the vise is tight on the sensor side. Also remember to use a second smaller screwdriver to push in on the locking clip to release it. Note. In the photo there is a cut at the end of the connector. It won't be on your side since I tried cutting the connector with a dremel.
