hi my name is XXXXX XXXXX ill try to help what engine is in your taurus
the code means either to much air is entering the engine or the o2 sensor is stuck producing low voltage, you will have to do some test to see if the sensor needs replacing, yes you have 4 o2 sensor in you car you have two on each bank of the exhaust one in front of each cat converter and one behind each cat converter, depending on which sensor your changing it could be hard the one you have a code for is bank two or the side of the engine closest to you when you stand in front of the car after the cat depending on the engine and if it is a flex fuel motor it may be hard to change hope this helps contact me if you need futher help
It is NOT a flex fuel motor -- what other info do you need about the engine/motor -- and what test has to be done to determine if the sensor needs replacing?
your have a v6 3.0 motor but i need to know if it is a 12 or 24 valve motor and the test that you can due is see is it had a vacuume leak
The manual doesn't say how many valves the motor has.
It sounds like you are telling me I have to go to a mechanic to determine what the problem is -- Is that so? And the light did not come back on after I checked the code -- so does that mean the problem went away, or does the light stay off after the code is checked?
are you still there
