6 Steps To Replace Oxygen Sensor

6 Steps To Replace An Oxygen Sensor

This video shows 6 steps to remove the old oxygen sensor & 6 steps to install a new Oxygen sensor.
Starting from the beginning when you received an engine warning light, what do you do?
I got the P0141 code (you may have other codes). It indicates that too much time elapsed before the oxygen sensor began operating properly. Either the heating element on the sensor is not working, or the heating circuit is open, many possible places that the wires are disconnected. Since the engine light only comes on a few days after reset, I decided it is more likely the sensor is not working.
The 2nd question is should it be genuine OEM part or universal sensor? Of course you are interested in this: where is the cheapest place for the genuine Honda oxygen sensor?

Diagnosis of the P0141 Code & Oxygen Sensor

Diagnosis of the P0141 Code & Oxygen Sensor

Got the P0141 code which is: the controller tracks how long it takes for the oxygen sensor to begin operation. If too much time elapsed before the oxygen sensor began operating properly, it will set P0141. There are 2 possibilities:
1. the heating element on the sensor is not working.
2. the heating circuit is open, many possible places that the wires are disconnected.
I measured the resistance of the heating element, which is about 6 ohm. Since after reset the engine light does not come on until a few days later, I decide just to replace the oxygen sensor.

P0141 is for the “secondary oxygen sensor” when you order from Honda. Or the “downstream oxygen sensor” when you order from third party store.

I will order one from Honda instead of using the Bosch’s Universal Oxygen Sensor.

Is Bosch Oxygen Sensor Installation Video Correct?

Is Bosch Oxygen Sensor Installation Video Correct?

Bosch is a big company. In its youtube installation video dated Aug 8, 2012 it showed animation of air flow along electrical wires with the instruction: “It is critical to understand that in order for the oxygen sensor to work properly air must be drawn into the sensor through the connecting wires. Therefore you must not solder the wires together. Doing so will result in a malfunctioning sensor.” Is Bosch correct? It is more than a year and the video has more than 10k views, but no one has pointed out the mistake, or is it me who is making a mistake?

Either this $56 sensor is the invention of the century or that animation of blue air is 200% wrong!

Please, please leave your comments below because I am trying to replacing the oxygen sensor on my car. Let’s see whether internet can bring the truth to light.
