Car Inspections: Top Triggers for Your Check Engine Light

Posted on

The primary purpose of your vehicle's check engine light is to alert you that there is an underlying issue with your car. However, since this light tends to come on at the most inopportune moments, it is not uncommon to find that some motorists simply ignore it assuming that as long as they can drive their vehicle that it must be something minor. The reality is that your check engine light can save you from expensive auto repairs if you pay attention to it, and it can also ensure that you do not find yourself in the unfortunate circumstance of finding yourself stranded in the idle of the road. Knowing some of the reasons why your check engine light would go off makes you better placed at understanding why you would need a car inspection and would encourage you to seek auto repairs post haste. Therefore, what are the top triggers for your check engine light?

Your vehicle's oxygen sensor has become compromised

One of the crucial components of your vehicle is the oxygen sensor as it functions to measure the volume of unburned oxygen that is present in the exhaust.  If there is a significant amount of oxygen in your exhaust emissions, it implies that fuel is not being burned efficiently. Insufficient fuel combustion will lead to increased pollution from your vehicle. On the other hand, if the oxygen levels are extremely low, it would imply there is a high amount of nitrogen oxide, which would severely diminish the performance of your vehicle. Overall, any imbalance noted by the oxygen sensor should be addressed immediately to prevent engine damage.

Your vehicle's fuel cap is compromised

In some cases, a fuel cap that is not functioning at optimum may trigger your check engine light. A faulty fuel cap will typically occur if the fuel cap has not been secured appropriately, is missing or if it has acquired significant damage. You could easily inspect this on your own, and any visible damages should have you seeking auto repairs.

Your vehicle's airflow sensor is compromised

The airflow sensor is tasked with determining what amount of air is making its way into the engine. This volume of air is what will establish the amount of fuel that is required to keep your engine running at optimum. If your airflow sensor is on the decline, the engine will not be receiving sufficient amounts of fuel. It would be prudent to determine whether your check engine light has been triggered due to this to avoid irrevocable damage to your vehicle's engine.
