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)
3
there are 4 o2 sensors
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 )
It has ( one oxygen sensor ) on the 1991 and 1992 Ford Explorers
There are 2 oxygen sensors.
My Chilton repair manual - engine wiring schematic shows ( 2 ) heated oxygen sensors for the 1993 Ford Explorer
A 2001 Ford Explorer Sport , with the 4.0 liter Single Over Head Cam V6 engine should have ( 4 oxygen sensors )
two oxygen sensors for air / fuel ratio (and another two oxygen sensors that are called catalyst monitors installed downstream )
