How many oxygen sensors does a 2004 endevor v6 have


Hi there:
There is a sensor located before a emission device called a catalytic converter that is located on both sides. The sensors in the back of the engine are called O2 sensor 1 bank one, (sensor before the catalytic converter) and O2 sensor 2 bank one (located after the converter).

On the front of the engine, going down you have two as well for there is a converter on both sides. first one coming from the engine is O2 sensor 1 bank 2 and then your failed one after the converter, O2 sensor 2 bank 2.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

This is Bank 1 (closer to the dash panel) Sensor 2 (located after the catalytic converter).

---
Note: A malfunctioning front oxygen sensor may cause fuel trim codes to set.
  1. Several Diagnostic Trouble Codes use specific terminology to refer to sensor location. The illustration and key below explain the following terms:
  2. Engine BANK Bank 1 is closer to the dash panel, (also referred to as RH or right hand). Bank 2 is closer to the radiator, (also referred to as LH or left hand).
  3. UP Refers to Sensor 1 or "front sensor". It is located closer to the exhaust manifold and before the catalytic converter.
  4. DOWN Refers to Sensor 2 or "rear sensor." It is located after the catalytic converter.
  5. The following examples show how to interpret oxygen sensor terminology:
  6. B1/S1 = Bank 1/Sensor 1 = Dash panel side, BEFORE the catalyst or "upstream"
  7. B2/S2 = Bank 2/Sensor 2 = Radiator side, AFTER the catalyst or "downstream"

WHERE IS MY OXYGEN SENSOR LOCATED


On almost every car, there is an O2 sensor located in the front, on the exhaust pipe, or manifold, and there is an O2 sensor located after the Catalytic converter. The front O2 sensor is the most important because it monitors the air/fuel ratio. The rear O2 sensor checks your Cat converter for proper operation and filtering.

Where is the ait temperature sensor located?


I believe they may be referring to the O2 Sensor, or Oxygen sensor. Being this is a 98, there may be two. If so, the first will be located on the exhaust manifold, the second, just before the catalytic converter. If there is only one equipped it will be located just before the catalyitic converter.

If you are not familiar with this part, it is the first "muffler" type part that is located just after the exhaust manifold and usually lies just under the passenger side of the car toward the front. You may need to raise the front of the vehicle to see it, as this is a small car and sits fairly low to the ground.

Typically, you will need a special socket called and O2 Socket to remove this and insert the new one, however if this is not affordable to you, then you can use an open end wrench. Be sure to disconnect the wiring harness first, then remove; and vise versa for inserting the new one.

Please let me know if you need further assistance with this matter.

Where is the bank 2 sensor 1 located.


Oxygen sensors are always numbered like this:

Bank 1 sensor 1
Bank 2 sensor 1
Bank 1 sensor 2
Bank 2 sensor 2

some manufacturers use a kind of shorthand that reads different, but means the same thing:
Sensor 1/1 or O2s 1/1
Sensor 2/1 or O2s 2/1
Sensor 1/2 or O2s 1/2
Sensor 2/2 or O2s 2/2

Bank 1 is always the side of the engine where cylinder number 1 is located and, of coarse, Bank 2 is the opposite side.
On a 4 cylinder engine, there is only 1 bank and it is always referred to as Bank 1.

Sensor 1 is always the upstream sensor (The one located BEFORE the catalytic converter)
Sensor 2 is always the downstream sensor (the one that is located AFTER the catalytic converter.

Most GM engines have #1 cylinder located on the left bank, (or Driver's Side) of the engine,

So, the answer to your question would be that you are looking for the sensor located before the catalytic converter on the right (or Passenger Side) of the truck.
