In this article, we’ll go over some issues the check engine light might signify and why it’s crucial to fix the issue as soon as possible.
Engine – Mass Airflow Sensor or Intake Tract
The engine’s MAF (mass airflow sensor) is responsible for measuring the amount of air entering the engine, helping to determine what amount of fuel is necessary to run your engine properly. Any leaks before or after the MAF sensor in the intake tract can trigger the check engine light. Sometimes, the sensor simply needs to be cleaned to fix the issue. Other times, the sensor may be due for a replacement. If left untreated, a broken MAF sensor can cause failure of other engine parts and reduce performance/fuel economy.
Believe it or not, your gas part is an important part of an entire, sealed system responsible for recirculating gasoline vapors from your gas tank, keeping them from escaping into the air. A faulty gas cap is one of the more common reasons behind a check engine light coming on. If you have left your gas cap open or if the gas cap is no longer closing the way it’s supposed to, you will likely see your check engine light come on very quickly. If not fixed, a faulty gas cap can cause fuel loss and errors in your recirculation system.
The catalytic converter in your vehicle split unsafe gases from safe ones. It helps to reduce the amount of harmful carbon monoxide that is released into the environment. A catalytic converter does not typically fail on its own – it’s usually caused by something else that is failing in the system. Because of this, simply replacing the converter or the oxygen sensors around it will not fix the problem. A blown head gasket, for example, is a common cause behind a failed converter. If left unchecked, your vehicle will not be able to pass emissions, will experience reduced performance, and the issues throughout your entire system will continue to get worse until the root cause is identified and taken care of.
Faulty Oxygen O2 Sensors
The oxygen sensors in your vehicle help the measure the amount of unburned oxygen in your vehicle’s exhaust system. If faulty, your engine will burn more fuel than needed and may cause damage to your spark plugs and catalytic converter. Oxygen sensors function in hundreds of degrees exhaust temperatures and are prone to fail once every 80,000 miles.
Spark Plug Misfires
Spark plugs ignite the air/fuel mixture within the combustion chamber of your vehicle, but if anything is wrong in the timing of that spark, you’ll have a misfire. There are a number of issues that can cause a misfire, including:
- Defective ignition coil
- Defective fuel injector
- Vacuum leak
- Worn spark plugs and/or wires
- Bad compression
If not fixed properly, your vehicle will experience reduced power, reduced fuel economy, and eventually mechanical failure in the engine.
