An illuminated check engine light doesn’t necessarily indicate that total engine failure is looming. However, you should still get to the shop ASAP for computerized diagnostics so that the problem can be identified and fixed before it causes bigger trouble. At Lloyd’s Automotive & Transmission Specialists, we specialize in check engine light diagnostics and repair in the greater Olympia area. Here are six common check engine light triggers.
Bad Catalytic Convertor
For your vehicle to be able to turn hazardous compounds into gasses that aren’t as harmful, you need a healthy catalytic converter. Symptoms of catalytic converter failure include darkened exhaust smoke, poor acceleration, and a stench like rotten eggs.
Failing Oxygen Sensor
O2 sensors keep tabs on how much unburned oxygen there is in the exhaust system. When there’s O2 sensor trouble, symptoms may arise such as increased emissions, worsening gas mileage, and catalytic converter trouble.
Issue with Battery/Charging System
When a failing battery causes low voltage at the computer, it can then cause the check engine light to turn on.
Faulty Spark Plugs
Indications of a spark plug problem include hard starts and worsening acceleration. Healthy spark plugs play an important role in helping your vehicle attain peak engine performance and gas mileage.
Failing Mass Airflow Sensor
MAF sensors monitor the amount of air coming into the engine. Signs of a bad MAF sensor include difficulty starting, rough idling, and decreasing acceleration.
Loose/Missing Gas Cap
If your gas cap isn’t securely fastened, then fuel may evaporate before your engine manages to put it to use. While this might not necessarily seem like an engine problem, it’s an issue that still sometimes causes the check engine light to come on.
