oxygen sensor? check engine?
Hey there everyone?'
My ranger started showing the check engine light (on and off) a few months ago.. After examining the engine I saw no problems and had others tell me that it is probably the oxygen sensor...
So, I went into my local parts store and questioned them on the prices... apparently there are two oxygen sensors on some rangers, and one on the others...
With a 97 ranger and a 3.0 what is my easiest way of checking how many oxygen sensors I've got?
Cheers, thanks

check for stored codes first.no sense in playing part swap games.
being erratic.i would suggest a gas cap oring replacement.as a first guess
ps there should be 2 with green plugs,(precats)
and 1 with a blue plug.(post cat)
get them from ford.to make sure you get the proper ones

yes, but they are year/type specific.you need an obdII scanner for 97 up ford.i have seen them as cheap as $120. us.
most garages arround here charge 50 bucks just to read codes.
the local autozone does it for free.worth the 20 mile trip for me.it plugs right into plug under steering wheel
do a search for obdII codes.there are a couple of pages that have them.a sheet usually comes with the scanner.so if someone does it for you.they should have one.or post it here i will leave the code discription for any #'s you get.
good luck

I agree with fauxexplorer...you have to scan for codes. Get the codes, post them and then people can help you. No need to replace O2 sensors until you know for certain that they are faulty.
OBD-II codes, explanations and possible causes can conveniently be found in the the "OBDII Codes" section of the thread entitled "Sticky: Technical Information" which is locked at the the top of this Forum. Check it out!
