I have a 1998 Ford Explorer 4.0L SOHC. The check engine light has been going off for a couple days and coming back on. I purchased am OBD II diagnostic tool and gave me the code P0153. Says the oxygen sensor has a slow response time. (Bank 2 Sensor 1). I have researched online and found completely different answers. One person said its on the driver side exhaust manifold the other person said passenger side on the exhaust manifold. I want to replace this myself, but want to replace the right one. Can someone please give me a descriptive answer to where it is. Maybe even give me a link with a picture of where it is located. They want to charge me $150 to change it, when I can get a new sensor for less than 40 bucks. Any help would be much appreciated!
