Common Causes of a Check Engine Light
1. FAILING OXYGEN SENSOR
​
Tucked into your vehicle’s exhaust pipe there are multiple small oxygen sensors that constantly tests the exhaust system to measure the air-to-fuel ratio. The sensor transmits that data to your vehicle’s computer, which relies on this information to create an ideal air-to-fuel mixture based on the driving conditions. Symptoms of a faulty oxygen sensor aren’t obvious to a lot of motorists, so the check engine light may be the first time you become aware that a problem exists. Fixing a serious maintenance problem like a faulty oxygen sensor can improve your vehicle’s fuel efficiency by as much as 40%, according to the U.S. Department of Energy.
​
2. LOOSE OR DAMAGED GAS CAP
​
The check engine light may be alerting you to a problem with your vehicle’s gas cap. Addressing the issue may be as simple as twisting the gas cap to ensure it’s tight or replacing a missing or damaged gas cap. While it may not seem like a huge problem, a loose, missing, or damaged gas cap will cause fuel vapors to escape and the EVAP system to not function properly. That, in turn, can lead to an illuminated check engine light.
​
3. BAD SPARK PLUGS
​
Spark plugs are small but mighty powerhouses. They generate the electric spark that enables your vehicle’s engine to start. But when spark plugs become worn-out, they can generate problems. If bad spark plugs aren’t replaced, they can trigger ignition problems, fuel waste, or damage to other parts of your vehicle. Worn-out spark plugs also can prevent your car from starting.
If the check engine light is signaling an issue with the spark plugs, it’s best not to put off getting the problem resolved. Otherwise, your vehicle’s issue could be more severe than just a check engine light. Bad spark plug wires can also be to blame for an illuminated check engine light, along with malfunctioning ignition coils. An ignition coil produces the electricity that enables spark plugs to ignite the mixture of fuel and air found in the engine’s combustion chamber.
​
Schedule an appointment at America Auto Repair, and one of our auto care professionals can put the spark back in your vehicle.
​
4. WEAK BATTERY
​
A weak battery may be the culprit behind an illuminated check engine light. When a battery is faulty or isn’t fully charged, it can’t send the proper amount of energy to your vehicle’s computer system. That, in turn, can cause the check engine light to illuminate. Your vehicle’s dashboard may also feature a battery light that comes on when there’s a problem with the battery or alternator.
5. BAD MASS AIRFLOW SENSOR
​
As its name suggests, the mass airflow sensor measures airflow so that the engine’s computer can help your vehicle run smoothly. When this sensor goes bad, your vehicle can stall, lose fuel efficiency, or idle roughly.The mass airflow sensor can be taken out and cleaned in some cases or can be swapped out for a new one. An airflow sensor issue may be related to a dirty air filter, so installing a new filter may help resolve the sensor problem. No matter the cause of a sensor problem, this situation can flip on your check engine light.
​
6. EGR VALVE PROBLEM
​
Your vehicle’s exhaust gas recirculation (EGR) value serves an important purpose: It helps reduce the emission of harmful nitrogen oxides by recirculating metered quantities of exhaust gas into the air intake system.
​
A faulty EGR valve can activate your vehicle’s check engine light. A faulty EGR valve that isn’t replaced can result in problems with fuel efficiency, power, and acceleration.
​
7. DAMAGED CATALYTIC CONVERTER
​
Your vehicle’s catalytic converter helps cut down on air pollution by removing pollutants from your vehicle’s exhaust. How does it work? The catalytic converter transforms three harmful compounds into less harmful compounds:
​​
-
Carbon monoxide
-
Hydrocarbons
-
Nitrogen oxides
One sign that your catalytic converter may not be working correctly is if you notice the smell of rotten eggs. Another sign: The check engine light comes on. Damage to a catalytic converter typically happens when faulty plugs or sensors have been neglected. Such damage can lead to lower fuel efficiency and higher operating temperatures.
​
You can help prevent your vehicle’s catalytic converter from giving out by keeping up with regularly scheduled maintenance. If you suspect there’s a problem with the catalytic converter, we can take care of that, too.
​
8. VACUUM LEAK
​
A vacuum leak may be another reason that the check engine light illuminates. Although a vacuum leak may not be hazardous, it can cause a loss of vehicle power and a drop in fuel efficiency. Given the number of parts in your vehicle’s vacuum system, it’s wise to let a trained Firestone Complete Auto Care technician fix a suspected vacuum leak.
WHY DOES MY CHECK ENGINE LIGHT COME ON WHEN I START MY CAR?
It’s common for the check engine light to come on momentarily when you first start your vehicle. This is a normal sign that your car is testing its circuits. However, if your check engine light stays on and does not turn off, it's time to have a professional at America Auto Repair run a diagnostic check to determine the source of the issue.
