Honda Civic Troube light is on it call bank 2 oxgen sensor Changeit out Light still on reset it took battery off to reset still on could sensor be bad

Hi Jesus, Im AL the owner of Big As Auto Repair.

If you have a 4 cylinder engine then you will only have two 02 sensors 1/1 is upstream and 1/2 is downstream. Upstream is the one closet to the engine and downstream is the one farther away from the engine.

If you have a six OR eight cylinder engine you will have four 02 Sensors. 1/1 means Bank One Sensor One. 1/1 and Bank one means right bank and right bank means the side with the number 1 spark plug. SO, 1/1 means, "Right Bank" Upstream 02 sensor. 1/2 means, "Right Bank" Downstream 02 sensor.

2/1 means, "Left Bank" Upstream 02 sensor and 2/2 means, "Left Bank" Downstream 02 sensor. Hope this helps and please visit my auto-repair-website at: http://www.bigasautorepair.com/

in barstool talk:
the rear oxy is toast. get a new one.
if v6 engine, then post that, and we an tell which it is. but is bank1 no matter, bank one means side of engine that has #1 cylinder

- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM) (NEVER)

Hi there:
You are right, DTC P0058 - HO2S Heater Circuit High Voltage Bank 2 Sensor 2

As far as replacing them, the only thing that has me wondering about a wiring issue. Keep in mind that power comes directly from the engine computer. Either the wires are broken or the computer is bad.

Aditionally, in THIS LINK could fin other descrtipion test and details procedure.

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.

2 simple solutions, disconnect battery for 5 minutes, or go to auto store and have them clear code, usually for free at most chain stores.

disconnect the battery for 15 minutes. The computer just may need to be reset. If it comes back on, it should store a code for you.

Stop by your local auto parts store and ask how many oxygen sensors the Honda Civic has installed. They are usually installed on the exhaust pipe before the catalytic convertor, and screw off with an open-end wrench. The heat causes the sensor to be a bit difficult to remove, and you will need to put some anti-seize compound on the threads of the new sensors. Most cars have 2 or 3 oxygen sensors.

Your local AutoZone can also put the diagnostic computer on you car which should indicate whether its actually a bad oxygen sensor, or they will read the error codes to tell you what the problem really is. Best of all, it's FREE.

if u have one oxygen sensor then u need to take a deep look at the bottom of ur car it will be somewhere at the Exhaust pipe if u have a catalytic converter then u will have two oxygen sensors one before the catalytic converter & the other will be after the catalytic converter. Note: the catalytic converter is located at after a little bit of beginning in Exhaust pipe.

P0041 Downstream Oxygen Sensors Swapped From Bank To Bank
How does a P0041 code trigger the check engine light? This code will trigger the light to come on under the following condition:

The Heated Oxygen Sensor Monitor, a strategy built into the computer, determines if the Heated Oxygen Sensor (HO2S) signal response for a change in fuel trim corresponds to the correct engine bank. If a response from the Oxygen Sensor being tested is not indicated, a trouble code will be set and the MIL (Malfunction Indicator Lamp) will illuminate.
Possible Causes:
Crossed Heated Oxygen Sensor harness connectors
Wiring swapped from one Oxygen Sensor connector to the other
Wiring changed at the computer connection or in the related harness

Autozone oxygen sensors do not function properly in Toyota vehicles. Just had a Tacoma yesterday with the same issue. New sensors, runs poor, check engine light on. Toyota sensors fixed it right now.
