How can I tell if my Vauxhall Astra has a faulty oxygen sensor?

I've been having some issues with my Vauxhall Astra and I suspect it may be due to a faulty oxygen sensor. Are there any tell-tale signs that can help me determine if this is the case?

An oxygen sensor that is faulty can cause a multitude of issues ranging from poor fuel economy to engine misfires. You can use a diagnostic tool to check for any error codes related to oxygen sensor malfunctions, but the most common signs are decreased gas mileage and a sluggish engine.

If your Vauxhall Astra is displaying abnormal levels of carbon emissions, it could be a sign of a faulty oxygen sensor. This can be checked by bringing your car to a mechanic who can perform a emissions test.

One of the most noticeable signs of a faulty oxygen sensor is a decrease in engine power and performance. If your car feels sluggish or takes longer to accelerate, it could be due to a faulty oxygen sensor.
