What problem is triggering my check engine light?
When the check engine light turns on, it's not necessarily an indication that your engine is about to fail. But you'll still want to bring your vehicle to the shop so that computerized diagnostics can be conducted. This way, any developing issues can hopefully be caught early enough to prevent the need for major repairs. Here are seven common reasons that the check engine light comes on.
Failing Catalytic Converter
A healthy catalytic converter prevents your vehicle from excessively polluting. When a catalytic converter isn't working properly, you may notice worsening acceleration or darkened exhaust smoke. A sulphurous smell may also emerge.
Bad Oxygen Sensor
Oxygen sensors have the important task of keeping tabs on how much unburned oxygen is present within the exhaust system. A faulty oxygen sensor can cause catalytic converter problems.
Faulty Ignition Coil
Healthy ignition coils provide the necessary spark for the engine to dependably fire up. Misfiring and power loss are indications of ignition coil trouble.
Failing Mass Air Flow Sensor
MAF sensors monitor the amount of incoming air and determine how much fuel needs to be injected with it. Symptoms of MAF sensor trouble include stalling shortly after starting your engine, as well as hesitations while accelerating.
Failing Spark Plugs
Faulty spark plugs can hurt performance and gas mileage. Vehicles made after 2000 can often go 100,000 miles before needing new plugs, but older automobiles usually need plug replacement at shorter mileage intervals.
Battery/Charging System Problem
A bad battery can lead to low voltage at the computer. This can then cause the check engine light to come on.
Loose or Missing Gas Cap
Though it might sound strange, a loose or missing gas cap sometimes triggers the check engine light. It's important that your gas cap stays on tight so fuel doesn't evaporate before your engine gets the opportunity to run on it.
