If you see an engine light on your Porsche’s dashboard, schedule an appointment at your local Porsche dealership immediately to get it checked out. The technicians will use a diagnostic scanner to read the trouble codes on your vehicle’s onboard computer and reveal the underlying problem.

Loose or Damaged Gas Cap
A loose or damaged gas cap is a common trigger for the check engine warning. The cap creates an airtight seal on the fuel tank to prevent fuel vapors from escaping. A loose or damaged cap allows vapors to escape, setting off the sensors in the evaporative emissions control system (EVAP). This causes a check engine warning on the dashboard, which you can resolve by replacing the gas cap.
Oxygen Sensor Failure
Your Porsche’s oxygen sensor analyzes how much unburned oxygen is in the exhaust after fuel is burned in the engine. It communicates with your car’s ECU to determine the right air-to-fuel ratio for optimal engine performance. If the sensor is malfunctioning, your Porsche will be unable to adjust the fuel mix correctly.
This can lead to too much or not enough fuel being burned, which reduces engine performance. If too much fuel ends up being burned, the increased emissions will trigger the engine warning. Replacing the faulty oxygen sensors will restore peak engine performance and efficiency.
Catalytic Converter Issues
The catalytic converter converts harmful exhaust gases into less toxic substances. It rarely fails unless another problem causes it to, like malfunctioning oxygen sensors, carbon buildup, or faulty spark plugs. If the catalytic converter is failing, it will trigger the engine warning light. This component is expensive to replace, so get it checked immediately before the problem worsens.
Faulty Mass Airflow (MAF) Sensor
The mass airflow (MAF) sensor analyzes the volume of air entering the engine and sends the data to the computer to determine the right fuel ratio. This ensures there is a proper air-to-fuel ratio in the engine cylinders for optimal engine performance.
Internal failure and contamination from old oil and debris can reduce the MAF sensor’s efficiency, throwing off its calculations. This creates an imbalance in the air-fuel ratio, causing a warning alert due to engine misfires and increased emissions.
Worn Out Spark Plugs
Worn spark plugs are unable to provide the right spark to ignite the air-fuel mixture in the cylinders. This causes random misfires, power loss, poor acceleration, and poor fuel economy. These engine problems cause the engine warning light to come on. With a diagnostic scanner, your technician can accurately diagnose the faulty spark plugs and replace them.
Don’t ignore an engine warning on your dashboard because it can lead to costly repairs down the road. Reach out to Porsche Warwick to schedule an engine diagnostic and repair.
