exactly where is of 02 oxigen sensor the ford windstar 2003
My Chilton repair manual - engine wiring schematic shows ( 2 ) heated oxygen sensors for the 1993 Ford Explorer
before and after the catylitic converter.
According to the engine wiring schematic in my Chilton book : For a 1999 Ford Ranger , 4.0 liter EFI , V6 engine : ( there are 3 oxygen sensors )
two oxygen sensors for air / fuel ratio (and another two oxygen sensors that are called catalyst monitors installed downstream )
There are 2 upstream 02 sensors just behind the exhaust manifolds, threaded into the exhaust pipes, one on each side. There are 2 downstream 02 sensors just behind the catalytic converters, one on each side as well.
Just after the air filter, toward the engine.
a 1998 car will have (2) 02 sensors per bank. In other words, a v6 or v8 will have a total of 4 sensors and a 4 cyl. will have 2 sensors. One is located before the catalytic converter and one is after or behind the cat.
According to my Haynes repair manual : For a 1997 Ford Explorer , 4.0 liter Single Over Head Cam , V6 engine : The engine wiring schematic shows ( 4 ) oxygen sensors
