Before you replace the oxygen sensors on your Defender 90, watch this video. Doug gives you tips and goes over the O2 sensor replacement process.
The Oxygen Sensor is one of the key sensors in this system. It is often referred to as the "O2" sensor because O2 is the chemical formula for oxygen (oxygen atoms always travel in pairs, never alone). It may also be referred to as the H2O2 for Heated Oxygen Sensor because it has a...
000 miles without failing. When the O2 sensor does fail, it will likely generate an error code and cause the check engine light to come on. This error code can be diagnosed easily at most auto parts stores free of charge. Replacement O2 sensors can also be purchased at most auto parts s...

If it’s a minor issue such as a glitch in the mass airflow or O2 sensor, it may fix automatically, and the light will go dark. However, if it still stares at you after three days, you have to apply the methods mentioned above to reset it. ...
Use the O2 sensor tool and socket wrench to screw in the O2 sensor onto the end of the truck exhaust system. It will thread onto the system like a bolt on turning and will get tightened on turning clockwise. Plug the car’s electrical connectors in the O2 sensors then. Step 4 – ...
How to Fix:Clean or replace the MAF sensor. #2 – Oxygen Sensor Malfunction Anoxygen sensor(aka O2 sensor) is device whose function is to monitor the exhaust emissions of the vehicle so that it can analyze the air-fuel ratio going through the engine of that vehicle. ...
Sometimes it might be difficult to remove an old sensor, as it could be seized in its thread. We found severalvideoson how to remove a seized O2 sensor. When replacing an air fuel sensor there are two options: to install an original (OEM) or aftermarket part. Aftermarket sensors work fin...
is it still supple enough to bend as needed to grip its attendant spud? is the plastic fitting okay? if the car is older and its hardened vacuum lines clearly haven’t been replaced in decades, you may want to go ahead and replace all of the vacuum lines and their plastic junctions ...
The next step is: you are going to see the back of the PCB board and the battery. There are two (2) screws on side of PCB board and you will want to remove those as well. Because the sensors are on the front-side of unit, it makes sense that the sensors to replace are on the...
