SOURCE: where is bank 1 sensor 1 on mitsubishi endeavor

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.

SOURCE: I need to know which O2 sensors are which: Bank 1

bank one upstream oxygen sensor on exhaust manifold bank two oxygen sensor after catalytic converter.tell me what code you are getting.bank 1 sensor 1 fuel system is too rich fuel pressure too high fuel pressure regulator leaking or more than 1 fuel injector leaking. fuel contaminated.check spark plugs if black carbon color fuel system too rich. if you getting code bank 1 sensor 2 check for air leaks in the exhaust system, air leaks intake manifold.look for vacuum lines leaks,look for vacuum leaks pcv valve and hose and make egr valve not stuck open or gasket leak.

P0421


Hi there:DTC P0421 - Warm Up Catalyst Efficiency Below Threshold (Bank 1)


Basically this means that the oxygen sensor downstream of the catalytic converter on bank 1 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.


You will likely not notice any drivability problems, although there may be symptoms. The code may be more likely to occur after the engine has had numerous cold starts in the past 1-2 days.



A code P0421 may mean that one or more of the following has happened:



The catalytic converter is no longer functioning properly
An oxygen sensor is not reading (functioning) properly
A sparkplug is fouled up


Possible Solutions: Measure the voltage at the oxygen sensor on Bank 1 (the rear sensor, or the sensor after the converter). In fact, it would be a good idea to test each oxygen O2 sensor while you're at it.


One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.


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.

REplaced the cat and 02 sensors. Did the recalls. Also did a tune up, excluding the fuel filter. PO421 code is on again. Checked for exhaust leaks and vacuum leaks. Flushed the injectors. Next is checking...

2005 gallant with O2 sensor engine light is one...how do I fix it?


have the engine light code scanned, and it'll tell you if it's bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1, bank 2 sensor 4.

Bank 1 is on the same side as Cylinder 1
Bank 2 is on the opposite side of Cylinder 1

Sensor 1 is located before the catalytic converter.
Sensor 2 is located after the catalytic converter
