How many O2 sensors are there on a 2000 explorer, 4.0L OHV Type X engine? I have been told a few different things? If you need more details let me know. Thank you

You have 3 oxygen sensors, 2 in the collector and one after the cat.

If i have a code about the upstream O2 sensor, does that mean that both of the sensors before the cat need to be replaced?

Chandler, the code should specify "bank 1" or "bank 2". This will tell you which side the troublesome O2 sensor is on.

Bank 1 is the passenger side, bank 2 is the driver's side.

Its bank 2, so does that mean i only have to replcae the one on the drivers side?

Hook up a scanner and monitor their function before replacing.
