This 02 sensor thing is ridiculus. My dealer wanted $120 US for the 02 sensor and $100 labour.This did not include the scope charge to read the trouble code. I went to my local auto supply guy and he gave me a part number for NTK equivelent.If you check your old Sensor you may see aford part number with NTK stamped below it. He could not match up the two lower sensors so I called NTK (you can go on their website..www.ngksparkplugs.com and find your part number). This is what they told me. The number on their website is for the two upper sensors (bank 1/2).
They have been told by Ford to redesign the lower sensors and they won't be available until August this year. Anyway they say that all o2 sensors can be substituted by a universal unit(except jeeps)the only difference is the connector plug.So save yourself a few bucks and use a universal unit. All you have to to is match and splice the wires and the connections are available on NTK's website. Unfortunately it does not make the rear upper sensor any easier to change!!
