7 Issues that Can Trigger Your Check Engine Light
Although something as minor as a loose gas cap can potentially trigger the check engine light, it's still best to play it safe and get to the shop for diagnostics when the light illuminates. This way, you can make sure that any developing issues are addressed before they worsen and necessitate more expensive repairs. Here's a look at seven common check engine light triggers.
Bad Mass Airflow Sensor
The mass airflow sensor is tasked with the important job of monitoring the amount of incoming air and then determining how much fuel should be injected with it. One symptom of mass airflow sensor trouble is the engine stalls soon after you start it.
Faulty Catalytic Converter
The catalytic converter turns carbon monoxide into a less polluting emission. Your catalytic converter may be faulty if you've noticed decreased acceleration or dark exhaust smoke.
Failing Oxygen Sensor
Oxygen sensors keep track of the quantity of unburned oxygen in the exhaust system. Oxygen sensor trouble could lead to issues with the catalytic converter.
Bad Spark Plugs
Failing spark plugs can cause a decrease in performance and gas mileage. As a general guideline, spark plugs in older vehicles should be replaced every 30,000 miles. In vehicles manufactured after the year 2000, you can often go 100,000 miles before plug replacement.
If your battery is failing, it can lead to low voltage at the computer, which can consequently cause your check engine light to illuminate.Faulty Ignition Coil
Ignition coils play a central role in creating the spark necessary for your engine to come roaring to life on all cylinders. Power loss and misfiring are two signs of ignition coil trouble.
Loose/Missing Gas Cap
Though it might seem like a trivial issue, a poorly-fitting gas cap can actually trigger your check engine light. By making sure your gas cap is on tight, you'll prevent fuel from evaporating before you get the chance to use it.
