Symptoms of Oxygen Sensor Failure in Land Rovers: What to Look For From Experts in Agoura Hills

Land Rover is one of the most sought-after luxury cars in the world that comes equipped with many top-notch sensors like the oxygen sensor that keeps a tab on the functioning of the vital parts in the high-end car. However, like other mechanical parts, the oxygen sensor can also encounter issues with its functioning leading to its failure.

There are various symptoms exhibited by your Land Rover when the oxygen sensor malfunctions. Here are the symptoms that you need to keep an eye on when the oxygen sensor fails.

Poor Fuel Economy

One of the leading symptoms of a failing oxygen sensor in your high-end car is poor miles per gallon of the car. However, unfortunately, most Land Rover drivers fail to notice this symptom because the majority of drivers think that as they are driving a luxury car, it is going to show less fuel economy.

Nonetheless, this misconception needs to be cleared right away because even your Land Rover has a fixed miles per gallon both while driving on the highway and inside the city. That is why when you see a drastic drop in the fuel mileage of your luxury car, you should immediately inspect the oxygen sensor in your vehicle.

The oxygen sensor measures the level of oxygen present in the exhaust gases of the car & this data is used by the onboard computers to adjust the fuel flow to the engine. Now, a bad O2 sensor can send erroneous data to the engine control unit (ECU) resulting in more fuel being delivered to the engine than required & resulting in poor fuel economy of your car.

Unusual Sounds from the Engine

Whenever you are driving a Land Rover, you are seldom going to hear anything unusual coming from under the hood of your car other than the occasional roar of the engine when you press the accelerator pedal. However, when the oxygen sensor of your luxury car fails, it is going to lead to several sounds coming from the engine of your car.

When driving with a defective oxygen sensor under the hood of your car, you are going to hear a pinging, knocking, or rattling sound coming from under the hood of your vehicle. The sounds you get to hear are primarily caused due to disturbances in the air-fuel mixture in the engine.

The disturbances in the air-fuel mixture are caused by failing oxygen sensor. However, the problem is that sometimes these unusual noises can be caused due to a host of other issues like clogged fuel injectors, or might even be caused due to engine failure.

The best thing that you can do to sort out the issue is get in touch with a Land Rover Specialist who can use advanced tools to scan the car to determine the real reason behind the unusual sounds coming from the engine of your car.

Emissions Test Failure

Nowadays, there is a huge attention on controlling the emissions from cars and the oxygen sensor plays a stellar role in controlling the emission of harmful gases from the exhaust of your vehicle. As the oxygen sensor is responsible for monitoring the amount of oxygen present in the exhaust gases and this information is used to adjust the fuel flow to the engine, any disturbance is it can lead to a host of issues.

Due to faulty data being sent to the onboard computer which leads to an increase in fuel flow to the engine, the engine is not able to burn the fuel properly and this leads to an increase in the emissions from your car. Most of the time this is evident when you get to see black smoke coming out the tailpipe of your Land Rover.

You can always go for a voluntary emission test to determine the functionality of your oxygen sensor & if you happen to fail the test, then the O2 sensor has failed.

Illumination of Check Engine Light

The warning light located on the dashboard of your car illuminates whenever there is something wrong in the car. The failure of the oxygen sensor is definitely going to illuminate the check engine light on the dashboard and you need to take it seriously.

You will require the assistance of a qualified mechanic to diagnose the real reason behind the illumination of the warning light & take corrective measures.

The above-discussed factors are some of the symptoms that you are going to witness whenever the oxygen sensor fails in your Land Rover. You need to take your Land Rover to a certified repair shop to get the oxygen sensor replaced at the earliest.
