A 2001 Ford Explorer Sport , with the 4.0 liter Single Over Head Cam V6 engine should have ( 4 oxygen sensors )
On a 1995 Ford Explorer : There are ( 2 ) oxygen sensors ( I believe there is one sensor in the outlet of each exhaust manifold )

My 1995 Ford Explorer with 4.0 L OHV has 2 oxygen sensors (Helpfull)
That would depend on what year of Ford Explorer and which engine you have ( my 1995 Ford Explorer with the 4.0 liter OHV , V6 engine has ( 2 oxygen sensors )
there are 4 o2 sensors
It has ( one oxygen sensor ) on the 1991 and 1992 Ford Explorers
There are 4 oxygen sensors on the 2001 ford f150 v6.
A 1994 Explorer has 2 oxygen sensors, they are either screwed into the exhaust manifolds at their outlets or into the ehaust pipes near the engine.
My Chilton repair manual - engine wiring schematic shows ( 2 ) heated oxygen sensors for the 1993 Ford Explorer
There are 2 oxygen sensors.
