AboutSkip Bollinger Expertise Heretofore, I will NOT answer any mechanical question. I am not qualified and can only offer speculations. You are better served by others that are true Techs. With that being said, please only ask about parts and locating obsolete Auto Parts. Thank you.
I have the ability to locate quite a few mechanical parts for American made vehicles fron the 1900`s to present. Some are OEM and some are aftermarket. This would include engine, brake and chassis parts. Body parts and trim are VERY difficult to find but you may inquire.
If you need assistance in repair, I have illustrated books for major American manufacturers that show some illustrations BEFORE 1974. If needed, I can supply repair manuals for your specific vehicle.
PLEASE REMEBER I'M A PARTS SPECIALIST, NOT A TECH!! Thank you..

Question I did a code reading on my ford explorer-2002,the code said that the oxygen sensor was bad-Bank one sensor two.T he problem is I'm getting mixed answers on the location of the sensor depending who I talk to, can you help.
Answer Don,
You need to ask someone smarter than I. I'm a Parts Professional, NOT a Tech but will offer what "I have been told" by my Tech customers (who don't always agree).
Bank #1 should be on the same side as #1 cylinder. You didn't state what size engine you have but I just looked in a filter catalog and it is either a V-6 or V-8. You just need to find #1 cylinder. That may be marked on the Intake Manifold. Sensor #2 should be the one AFTER the catalytic converter. It is also known as the "downstream" sensor.
I hope I have not misled you. If I were in your shoes, I'd equerry 3-5 people and take note of the majority answers. NOW a word of caution... Just because the scanner says there is a problem with bank 1 number 2 Ox sensor does NOT MEAN the sensor itself is bad. ALL the scanner is telling you is the computer has a problem with that circuit. It could be a burnt wire, bad connection or a bad sensor. Before you run out and buy a new sensor, check out the plug (for corrosion) and the wires (for burns). More often than not, it will be the sensor but I just wanted to let you know there could be other problems causing the code. I hope this helps a bit. Good luck. I hope you and your family have a safe and happy 4th.
