My 1995 Ford Explorer with the 4.0 L OHV engine has 2 , so I'm assuming your 1995 Ford Ranger 3.0 L would also have 2
My 1995 Ford Explorer with 4.0 L OHV has 2 oxygen sensors (Helpfull)
That Vehicle has 2 oxygen sensors.
Check
On a 1995 Ford Explorer : There are ( 2 ) oxygen sensors ( I believe there is one sensor in the outlet of each exhaust manifold )
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 )
On a 1995 Ford Ranger : There is ( 1 ) electric fuel pump INSIDE the fuel tank . The fuel pump is installed from the top of the tank
The ( 1996 ) Ford Ranger SuperCab holds ( 20.0 U.S. gallons )
there should be 3/1 on the left header then 2 going back
There are three, two just below the manifolds and one after the catalytic.
If it's like a 1991 Ford Explorer ( with the 4.0 liter V6 engine ) It has ( 1 ) oxygen sensor
I was looking in my Chilton book at the engine wiring schematic for a 1993 Ford Ranger 2.3 liter 4 cylinder and I only see ( 1 ) heated oxygen sensor
( two ) I believe they are in the outlets of the two exhaust manifolds
