What is an oxygen sensor?
Popularly known as the lambda sensor, the oxygen sensor has been around since the 1960s. Initially, it was designed for Bosch and measured the amount of oxygen contained in a gas.
Although the initial design contained ceramic coated zirconia and platinum, planar sensors have become the standard for mass production.
Today, all modern cars come with an oxygen sensor to help improve the car’s performance.
You can find the sensor in the emission systems. It is responsible for sending information about the oxygen level in your car to the engine computer, where necessary adjustment is made.
Notably, the oxygen sensor influences your vehicle’s performance while alerting you if there is any trouble with your emissions.
Why people bypass O2 sensors?
Most people bypass their oxygen sensors because it is the best means to tune the car engine.
For those less skilled in tuning engines or in off-road racings, bypassing the O2 sensor is the most effective alternative.
Besides this, the other reason for bypassing the oxygen sensor is if you do not have a catalytic converter in your car.
You do not have to experience the check engine light turning on constantly.
What to check before bypassing your catalytic converter?
We will not recommend you bypass your catalytic converter without knowing what to check.
Firstly, you should know the converter installed in your car. Usually, it should be easy to determine if you are using a joined or two separate part converter.
For beginners, if the converter is joined, it will be harder to bypass since you must combine the airflow and exhaust without being seen or caught.
Therefore, it is preferable to bypass a two-piece converter than a combined converter.
Secondly, you need to determine the space beneath your car to do the work. Peradventure, there is not any adequate space; you might reconsider it instead of causing an additional problem to your converter.
Step by Step Guide on How to Bypass the O2 Sensor
Before we unveil how to bypass catalytic converter check engine light, you need to get your equipment ready for the process.
Interestingly, you do not have to invest in an expensive item for this guide. With a hydraulic jack, penetrating fluid, adjustable wrench, and four jack stands, you are ready to bypass your car’s oxygen level.
Step-01: Preparation phase
Before starting the process, you should allow your car to cool if you previously used it since you are working with the engine. Allowing it to cool after a couple of hours is important.
Step-02: Losing the nuts
After the temperature has reduced, disable the cables that connect to the negative battery terminal. You will see a nut beside the cable clamp; gently take it off.

Step-04: Locate the pinch welds
Look for the front pinch welds and place the jack under them. Slower lower your vehicle so that it stands on the jack stands.
Step-05: Locate the O2 sensor
After locating the pinch welds, you need to look for the O2 sensors. Normally, it looks like plugs that protrude from your engine’s exhaust system.
You will find each of the O2 sensors at the catalytic converter’s front and rear sides.
Step-06: Unhinge the wire
Close to the O2 sensors, you need to remove the embedded electric wire attached to the sensor carefully.
Ensure you squeeze to release it before pulling it slowly from your O2 sensor housing unit.
Step-07: Removing the sensor
You need to rotate the O2 sensor in a counterclockwise (left-hand) position to remove the sensor. You can use a remove tool at this stage.
Insert the dummy O2 sensor by rotating it towards your right (clockwise) position. Insert it into your exhaust system before connecting it to the electrical wiring system.
Step-08: Finalizing everything
Lower your car slowly as you remove the jack. Once it is safely lowered, you can start the engine to check if the engine light comes on.
