According to my Haynes repair manual :
( 3 ) for the V6 engine and ( 4 ) for the V8 engine
4 ======================================================= The above answer is correct if you have the 5.0 liter V8 engine in your 1996 Ford Explorer , but if you have the 4.0 liter EFI , V6 engine ( VIN " X " ) there are ( 3 oxygen sensors )
there are 4 o2 sensors
There are 2 oxygen 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 )
Look on the exhaust system before and after the catalytic converter.
one because its a pre obd2 vehicle
( two ) I believe they are in the outlets of the two exhaust manifolds
A 2001 Ford Explorer Sport , with the 4.0 liter Single Over Head Cam V6 engine should have ( 4 oxygen sensors )
The oxygen sensor for a 1996 Infiniti I30 has 3 wires. The car actually has two O2 sensors, a front and a rear. Both sensors are the three-wire type.
The O2 sensor on any vechicle will be located on the exhaust manifold.
Screwed into the exhaust pipes
1985 to 1995 have 1 1996 on up have 2
