sensor located in exhaust manifold. Do I take off the coil pack & get at it from the top?
How do I access upstream sensor? on 1997 Ford Contour
it does come out the top. you may have to remove some items to acess it. you can get the socket for it from a parts store for a reasonable price. make sure you get a good quality replacement o2 sensor.
im not sure but my best answer would be if you can see it thats a plus, unbolting something simple as a coil pack to gain easier access to the sensor do it. my rule a thumb as a mechanic dont take anymore off than you half to. but where a person is doing themselves move a couple of things your not charging yourself by the hour!
