Just after the air filter, toward the engine.
My Chilton repair manual - engine wiring schematic shows ( 2 ) heated oxygen sensors for the 1993 Ford Explorer
two oxygen sensors for air / fuel ratio (and another two oxygen sensors that are called catalyst monitors installed downstream )
Most oxygen sensors are heated oxygen sensors.
All O2 sensors (AKA Air/Fuel sensors) are threaded into the exhaust system. Some before the catalytic converter (upstream) and some after the catalytic converter (downstream).
an o2 sensor is the same as an oxygen sensor. vehicles can have up to 4
The 2005 Ford Freestar is equipped with a total of four oxygen sensors. There are two upstream (pre-catalytic converter) sensors and two downstream (post-catalytic converter) sensors for each bank of the engine. These sensors help monitor the exhaust gases to optimize fuel efficiency and emissions control.
The 02 sensors are in the exhaust pipes but don't know about the updraft sensors.
exactly where is of 02 oxigen sensor the ford windstar 2003
before and after the catylitic converter.
There are several 02 sensors in that vehicle depending on which engine you have. They are all threaded into the exhaust system at various points.
Where is the shiftseleniod con a 02 ford focus
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
