try www.autozone.com check on repair info and components location. Two. There is an upstream sensor before the catalytic converter, and a downstream sensor immediately after.
There are 2 oxygen sensors.
On a 1998 Ford Explorer Sport : If it has the 4.0 litre EFI engine ( which is an over head valve / pushrod design engine / the 8th character of the VIN is an " X " ) there are ( 3 oxygen sensors ) If it has the 4.0 litre SOHC engine ( the 8th character of the VIN is an " E " ) there are ( 4 oxygen sensors )
A 2001 Ford Explorer Sport , with the 4.0 liter Single Over Head Cam V6 engine should have ( 4 oxygen sensors )
It has two oxygen sensors. One at the front of the catalytic converter and one after it.
The 4.0 liter OHV engine has ( 3 ) The 4.0 liter SOHC engine has ( 4 ) The front ( 2 ) oxygen sensors are used in the adjustment of the engine air / fuel ratio
two
Let me guess you have a service engine soon light on and the computer is saying it's your Oxygen sensors. Oxygen sensers are normally located on the exhaust pipe, within 12 inches of the exhaust manifold, you will probably have to get underneath the van to see them. I think it's just emissions stuff nothing real important
This is only going to answer half of the question : On a 1995 Ford Explorer , 4.0L EFI , V6 engine ( which is an Over Head Valve / pushrod design ) There are ( 2 ) oxygen sensors * I BELIEVE they are in the outlets of each exhaust manifold *
Both oxygen sensors are in the exhaust pipe, one under the front of the engine, one roughly under the passenger seat are.

No.
the o2sensor(oxygen sensor)is on the exhaust if i recall right. There are (2) oxygen sensors on the 2001 Dodge caravan (in this case Sport / SE edition) One is accesable under the hood the other is down in the exaust array past the catalytic converter. If your error message is showing that your heating element is out in the O2 sensor... its the front sensor.
