When the sensor is defective, it sends over a skewed set of data, which often means the engine will burn more fuel than necessary. This has the immediate effect of making the car less fuel efficient, as well as increasing emissions. More pressingly, it can also cause long-term and expensive damage to the spark plugs and exhaust system.<\/p>\n
Insecure or faulty fuel cap<\/h3>\n

<\/p>\n
Sure, it might be one of the least mechanically complex parts on your car, but it\u2019s important not to underestimate how vital your fuel cap is to the overall engine system. It seals the fuel system and in doing so regulates the pressure inside the fuel tank, which creates the optimum environment for fuel delivery. Not just that, but it also prevents environmentally damaging fumes from escaping. The system will see a faulty or unsecured fuel cap as a major issue, and rightly so!<\/p>\n
Faulty mass airflow sensor<\/h4>\n
The mass airflow sensor is another crucial part in the fuel delivery system, as it works with the oxygen sensors to regulate how much air gets into the engine. Unless it\u2019s functioning properly, you can end up with rough idling, unexpected changes in throttle, and issues when starting the car. It can also damage the oxygen sensors and spark plugs.<\/p>\n
The first steps to take when your check engine light comes on<\/h3>\n
Even if you think you know the reason that your check engine light has come on and you reckon it\u2019s only a minor problem, it\u2019s still very risky to ignore it. Some drivers have admitted ignoring the light for more than 12 weeks, which is one heck of a gamble to make, even with a minor yellow or orange light! Here are some of the first steps it\u2019s worth taking if you notice yours illuminate:<\/p>\n
Tighten the fuel cap<\/h4>\n
As it\u2019s one of the most common minor malfunctions, you may find that you can fix an orange or yellow light by the simple expedient of stopping and re-securing the fuel cap. Then, try continuing on. You may find that your light resets after a short delay. Even if it does though, we\u2019d recommend getting it checked out by a professional mechanic, just in case.<\/p>\n
Use built-in diagnostic features<\/h4>\n
Many modern cars have detailed diagnostic features for you to utilise, beyond the comparatively simple engine check light. If you\u2019ve got the knowledge and ability to use these for yourself, it\u2019s worth doing so in order to narrow down the problem. In some cases, you may even be able to fix the issue yourself, but if not it gives you valuable information to pass to the professionals.<\/p>\n
Find a safe place to pull over<\/h4>\n
This is especially important if your engine is showing a red light – find a place to stop and do so, as it\u2019s likely warning you of something that could put you in immediate danger. This may involve ultimately getting the vehicle towed, which is far from an ideal scenario, or a roadside repair. Either way, though it may be a lot of hassle and bother, it\u2019s still far better than the alternative of risking your safety!<\/p>\n
Apart from in the most serious of instances, you may find that when you take it to the mechanic, the problems aren\u2019t as worrying as you may have first thought. The electrics on some cars can be particularly vulnerable to \u2018gremlins\u2019 and therefore may be quick fixes.
