Why is my European car's check engine light on?

Why is my European car's check engine light on?When the check engine light comes on, it isn't necessarily a sign that engine failure is imminent. Nevertheless, you'll want to bring your vehicle to the shop so that accurate diagnostics can be completed. This way, any developing problems can hopefully be resolved before they worsen. Here's a look at seven common reasons the check engine light turns on.

Failing Ignition Coil

To reliably generate the spark needed for your engine to fire up, you need healthy ignition coils. Signs of ignition coil trouble include power loss and misfiring.

Bad Battery/Charging System

If a failing battery causes low voltage at the computer, then the check engine light could get triggered.

Faulty Catalytic Converter

Indications of a catalytic converter problem include worsening acceleration and dark exhaust smoke. It's important that your catalytic converter is working properly so that carbon monoxide is converted into an emission that is less harmful to the environment.

Bad Oxygen Sensor

Oxygen sensors oversee how much oxygen is in the exhaust system. Based on the information gathered by the oxygen sensor, the engine can make any necessary adjustments to achieve peak operating efficiency. Oxygen sensor trouble may lead to a catalytic converter problem.

Failing Mass Air Flow Sensor

MAF sensors keep tabs on the quantity of air coming in and calculate how much fuel needs to be injected with it. A bad MAF sensor may cause your engine to stall out soon after you start it.

Faulty Spark Plugs

As old, dirty spark plugs repeatedly misfire, a lot of fuel can go to waste and engine performance can worsen. Vehicles manufactured after 2000 can often go 100,000 miles before plug replacement, while older vehicles usually need new plugs more frequently.

Loose/Missing Gas Cap

As strange as it may seem, a poorly fitting gas cap can cause the check engine light to illuminate. It can also allow fuel to evaporate before you get the opportunity to use it.
