There are some cases where a professional help might be needed for replacement of Mini auto parts USA. On the other hand, some matters could simply be solved on your own. Your oxygen sensors happens to be amongst those things. Follow as we share what it is and when you should replace it.


What is an Oxygen Sensor? Oxygen sensors are designed to do a very simple job. There happens to be an oxygen sensor tip installed inside the exhaust pipe, which is responsible for observing the percentage of oxygen in the exhaust. There could be two cases when it comes to oxygen sensors. 1. The amount of oxygen is too little (Rich mixture) 2. The amount of oxygen is too much (Lean mixture) Both cases are problematic. In either case, the oxygen sensor will be sending signals to the ECU to adjust the amount of oxygen and fuel entering the engine. Considering the rules and regulations regarding vehicles emitting harmful fumes, it is important that your oxygen sensor is working perfectly. Moreover, it could also result in your catalytic converter being damaged, which could amount to further expenses.

Signs of a failing O2 Sensor 1. Check Engine Light The check engine light turning on in the dashboard is the first sign that could show up. A faulty oxygen sensor will and should turn the check engine light on, indicating a problem. However, the catch with check engine light is that it could light up due to number of reasons and not necessarily due to a faulty oxygen sensor. Therefore, getting the vehicle scanned should be the wisest option.

2. Engine Sounds Rough If you happen to observe that your engine is running rough or the RPM meter is abnormal, it could be a sign of a faulty oxygen sensor. The reason being, that when the mixture of oxygen and fuel happens to become too lean or too rich, the engine is supposed to become less efficient. A faulty oxygen sensor in such case could easily disturb air to fuel ratio, combustion intervals and engine timing etc. hence the engine performing roughly.

3. Bad Gas Mileage If the above mentioned reasons are not the case, then this one could definitely be. Since as already mentioned that the oxygen sensor is responsible for looking after the air to fuel mixture, it is directly related to the economy of the vehicle. If you notice that your vehicle is consuming too much fuel, might be that you have an oxygen sensor that has gone bad. You shall experience a gradual decrease in your vehicle’s fuel economy, which should be diagnosed as soon as possible.

Conclusion In the end, oxygen sensors will last up to 15 years or anything between 60,000 to 90,000 miles. Since it happens to be an electrical component, it will fail over time. Therefore, keeping in mind the strict rules and regulations and most importantly the engine, you should replace the oxygen


sensor as soon as it becomes faulty. And always look for quality Mini auto parts USA for replacement.
