If you’re like most drivers, you take your car for granted. You don’t think about the systems that keep your vehicle running – you simply drive it and rely on them to do their job. But what happens if one of these systems fails? In this article, we’ll explore what happens when a car has a bad oxygen sensor, and how to fix it.
What is a bad oxygen sensor?
Bad oxygen sensors can cause your car to not start, or to run poorly. If the sensor is not functioning properly, it may not be able to detect low levels of oxygen in the air. This can lead to problems with starting the car, or erratic driving. If the sensor is not replaced, it can lead to an engine failure.
