7 Possible Check Engine Light Triggers


7 Possible Check Engine Light TriggersAn illuminated check engine light doesn't necessarily mean that an automotive catastrophe is near. Still, it's best to get your car to the shop for computerized diagnostics so that any developing issues can hopefully be nipped in the bud. Here's a look at seven reasons the check engine light turns on.

Faulty Mass Air Flow Sensor

Mass air flow sensors monitor the amount of incoming air and determine how much fuel should be injected with it. A mass air flow sensor problem could cause your engine to stall soon after you start it up.

Bad Spark Plugs

When spark plugs fail, you may see a decrease in performance and gas mileage. As a general recommendation, spark plugs in older cars should be changed every 30,000 miles. For vehicles manufactured after 2000, you can often go 100,000 miles before replacement is necessary.

Failing Catalytic Converter

A healthy catalytic converter does the important job of turning carbon monoxide into a less harmful emission. A catalytic converter problem may be present if you notice worsening acceleration or darkened exhaust smoke.

Bad Oxygen Sensor

Oxygen sensors oversee how much unburned oxygen is in the exhaust system. An oxygen sensor problem may cause a reduction in fuel-efficiency, as well as catalytic converter issues.

Loose/Missing Gas Cap

It might seem bizarre, but a poorly fitting gas cap can potentially trigger the check engine light. A properly sealed gas cap will ensure that fuel doesn't evaporate before you get the chance to use it.

Bad Battery/Charging System

When a battery fails, it can lead to low voltage at the computer, which in turn can cause the check engine light to come on.

Failing Ignition Coil

Ignition coils are integral to creating the spark that your engine needs to come roaring to life. Misfiring and power loss are signs of ignition coil trouble.
