I been checking my codes with the Auto Zone OBD scanner and I was told that it does not provide the exact codes for my 1999 Ford Explorer. I had oxygen sensors codes show up when I used the Autozone scanner and I've changed the sensors twice. Would anyone know which Check Engine light scanner is best for my 1999 Ford Explorer? Also, I've only found three sensors under my car two near the engine Bank 1 and bank 2. and the other before the Catalyst converter. I was not able to locate the fourth bank 1 oxygen sensor. can someone tell me where its at?

On a V-6 or V-8 engine youshould only have three O2 sensors. One on each pipe or exhaust manifold coming out of the engine and one after the catalytic convertor.
Most O2 sensors will outlast an enigne or go 100K-200K miles. There are many things that can give a false reading to make it read an O2 sensor.
If you do not stay on top of oil changes or tune ups or there is significant oil usage from wear and tear these mechanical and chemical changes (dirty nasty oil) will give false O2 sensor readings.
Best ot have a full engine diagnostic to get the whole picture before spending anymore money on parts you don't need.
Good Luck!

YOU SHOULD GET THE VEHICLES COMPUTER SCANNED AND CHECK FOR ANY PROBLEMS AS WELL AS CODES AND THEN YOU WILL HAVE A GOOD IDEA ON WHAT THE PROBLEM TRULY IS.
TRY FINDING AN INDEPENDENT SHOP INSTEAD OF THE DEALER OR A CHAIN STORE BECAUSE YOU WILL BE OVERALL MORE PLEASED WITH THE FINDINGS AND THE SERVICE.
LEAVE IT THERE WITH THEM SO THAT THEY CAN FIND THE PROBLEM FOR YOU, IT WILL BE A LOT BETTER THAN JUST REPLACING PART AFTER PART AND NOT DOING ANY GOOD.
