how many sensors are needed for a 2002 mountaineer?

Dear Mickey, I'm pretty sure you already got your answer, but for anyone else who does not know who many oxygen sensors your vehicle uses, I found the only reliable way is to inspect your exhaust manifolds top and bottom. They are screwed directly into the manifold itself. Four cylinder vehicles probably have one(1), six cylinder vehicles probably have two(2), I think eight cylinder vehicles can have two(2) or four(4). If you cannot perform this inspection then you won't want to do the job yourself. When working under a car, always support it with jack stands. Don't trust a jack by itself.

Don't know without knowing the engine and exhaust system. But you should be able to tell by going to www.bosch.com, find oxygen sensors and your vehicle, engine, and exhaust system. Sensors after catalytic converters are usually different model than those before converters, and sensors on each side of a "vee" type engine may, or may not be different. It often depends on VIN number.

I dont know specifically..but...my v-6 required 3. 2 upstream...1. Downstream. My older ford f-150 requires 4...2 up and 2 down. Any auto parts place should b able to tell u for ur vehicle

It has been awhile but I am fairly certain that all 4 sensors are the same so should work just fine. After I installed mine, drove around and the check engine light went out on its own. Joe

this one does only have 2 sensors included not sure how many inputs. I had an installer put it in, I do recall him saying you could add more stuff to it just not sure what all could be added. I do love this system though. Wish I had done it years ago.

The same sensor that I received has only two wires. READ CAREFULLY THE INSTALLATION INTRUCTIONS AND Y you will be on your way. Enjoy!

The item description was a little confusing but mine came with two sensors as hoped.

Well you take a look at your old sensor one is up stream and the other is down stream.the one closer too the engine is up the other in the middle is down.Then you would check how many wires and what are the colors. write every thing down.when on amazon put make model it will tell if its fits make sure you check everything.

o On my Toyota the heated sensor is the rear one. Heated sesors have 4 wires, others have 2. Lee

I can't answer your question since eventually I didn't use these sensors since it doesn't fit my car

You do not need to purchase two. If your system only has one sensor that's all you need. In my case, the water sensor failed and this item replaced it perfectly. My system's original air sensor is still working fine and I expect it will for a long time as it is sheltered from the elements.

Same for both. I replaced both sensors on my 2005 Yukon 1500. Worked great.

I do not recall, however a friend of mine did have to replace a couple of sensors and they gave him the replacements immediately. Hope this helps.

Single sensor. Put mine in about 2-3 years ago and no issues since. Took approx 1 hr for me and a friend to change in the driveway. Mine were rusted pretty severely. Biggest issue was getting the wiring disconnected without breaking the connectors.

Not sure of the question. But I had problems trying to program it. I am very techinal and have a bad habit of reading instructions and thinking I know how to do it ! Go back, READ the instructions ,and follow it step by step. I have two sensors and base. It works perfectly!!! Take the time to read it again !!!

The one I purchased came with two sensors. And they work WONDERFULLY!!! I bought two more, and added them. These little detectors are great. They are sensitive, too (placement is key).

I have a 2001 taco and both of my sensors are on the passenger side. 1 is between the engine block and the first catty converter. the 2nd (sensor 2) is between the 2 catty converters.

Google the sensor and display to find the instructions. I seem to recall that there's a jumper on the circuit board that you need to set for one or two temp sensors. So I'd take a look at the docs before I gave up.

No the sensors are not necessary. I have not connected any of the sensors as of yet because it is in a small area and I have direct sight to my equipment.
