Where is the bank 1 sensor 2 located on a mitsubishi endeavor 2004?

you don`t say if this is a 4 or 6 cylinder. 4 cylinder follow the exhaust pipe down from the manifold towards the back. the first sensor you come to in the exhaust is sensor 1 continue until you come to the second sensor this is sensor 2. if this is a 6 cylinder then find which side cylinder #1 is on and do the same thing.

What is the best way to remove O2 sensor bank 1 sensor 2?

Here is the low-down on oxygen sensors, and their location designations explained:

Oxygen sensors are screwed into the exhaust system at various points. Some people say that there are 4 oxygen sensors, but technically, that is not correct. Only the front 2 are considered oxygen sensors.

These oxygen sensors are screwed into the exhaust pipe or directly into the exhaust manifold, one on each bank. Because they are in front of the catalytic converter, this is often referred to as 'upstream'.

The other 2 are actually called catalyst monitors. They are oxygen sensors, but they serve a different purpose. They monitor the activities of the catalytic converters, thus the name, catalyst monitors. They are screwed into the exhaust one on each bank, after, or downstream, of the catalytic converters.

On a 4 cyl engine, there are only a total of two such sensors, the one in front of the catalytic converter is the O2 sensor, the one behind the cat is the catalyst monitor.

The location names for them are as follows:
  • On a 4 cyl, the front / upstream is called "bank 1 sensor 1" and the rear / downstream sensor is called "bank 1, sensor 2."

  • On a V6 or V8 engine:

    • the passenger side bank on a forward facing engine, or the bank closest to the firewall on a transverse mounted engine, is bank number 1, so the forward / upstream sensor on that bank would be "bank 1, sensor 1."

    • The driver's side bank (forward facing mount engine), or front bank (transverse engine) would be bank number 2, thus the forward / upstream sensor on that bank would be "bank 2, sensor 1," and the rearmost / downstream sensor on that bank would be "bank 2, sensor 2."

How many oxygen sensors does a 2004 endevor have

Hi Santiago:
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.

Thank you for using FixYa, have a nice day

Where is bank 1 sensor 1 on mitsubishi endeavor 04' four cylinder??

There are only V6 endeavors in the US, are you certain you do not have a 3.8L V6?

Bank 1 refers to the side of the engine that contains cylinder number 1. This is the side of the engine nearest the firewall.
Sensor 1 refers to the first sensor off the manifold, or closest to the engine.
This also is the O2 sensor that is located before the catalytic converter in the manifold. Sensor 2 is located after the catalytic converter, further down below the car.

Bank 1 Sensor 2 is located on the Right Hand Bank - After the catalytic converter. It is on the bank closest to the firewall and after the catalytic converter.

Hope this helps.
