Bosch Oxygen Sensor Part Numbers
I have a 2000 Ranger V6 3.0L (Flex fuel) and manual transmission with over 130K miles. I have been getting some codes on one of the upstream O2 sensors, so I am planning on replacing both. In fact I might consider replacing the downstream sensor as well.
As I was looking on Bosch's web site for the part numbers, I noticed they list 4 sensors (2 upstream and 2 downstream) my year model/engine.
On the vehicle I do see both upstream sensors, but only 1 downstream sensor.
Does anybody know what the 4th sensor listed by Bosch is?
