Should I replace all my oxygen sensors? I am getting intermittent engine check lights and I have been told to replace my catalytic converter and the oxygen sensors. My mileage has also decreased. I do not care to replace the catalytic convertor; however, the sensors probably need replacement. How many oxygen sensors are there and where are they located? I have been told anywhere from three to five sensors. Please let me know how many I should replace and if there is a diagram or a picture somewhere that will tell me where they are. I have a Ranger XLT with the 6 cyl 3.0 liter engine, 4WD, manual transmission.
Thanks!
Thanks!
