There are four, if it's a V-8.
Where is the engine oil cooler on a 1998 Ford Econoline van E150
where are the oxygen sensors on a 2004 ford escape with a 3.0 engine
There are 2 Oxygen sensors. One is on top of the catalytic converter called the upstream and the other is at the bottom of the catalytic converter called the downstream.
Since oxygen sensors are always in the exhaust system, that's where you'd find it. There are at least two and as many as four on any late model vehicle with a V-8.
I believe there are 2 oxygen sensors that are used for air / fuel ratio and 2 oxygen sensors that are downstream from the catalytic converters and are called catalyst monitors
On my 1998 Ford Expedition XLT , There are 4 Oxygen sensors. 1 each in front of the Cats. and 1 each behing the cat. for a total of 4 Oxygen Sensors.

I have a '95 E150 and a '96 E250, both are 4.9 straight 6 cyl. One has 1 O2 sensor and the other has 2, one on each half of the exhayst manifold. I believe the 96 has 2. but it is an E250, not sure about the '96 E150.
There are 4 oxygen sensors on the 2001 ford f150 v6.
