A dashboard warning light is your vehicle’s first line of communication when something is malfunctioning. The Check Engine light, in particular, signals issues with engine components, emissions, or other systems that may affect performance. At 8 Cylinders Auto Repair in Philadelphia, we perform expert diagnostics to pinpoint the root cause and implement efficient repairs.
What Causes the Check Engine Light to Turn On?
Common issues that trigger a Check Engine light include:
- Oxygen sensor failure: Can increase fuel consumption and affect engine efficiency.
- Loose or missing gas cap: Often a simple fix after refueling.
- Catalytic converter problems: Converts harmful emissions; failure can lead to poor fuel economy.
- Ignition coil or spark plug issues: Prevent proper combustion; may cause rough idling or misfires.
- Bad spark plug wires: Affect ignition timing and engine performance.
- Mass airflow sensor failure: Impacts air-to-fuel ratio and can cause rough idle or starting issues.
Ignoring a Check Engine light can escalate minor problems into costly repairs.
How OBD-II Codes Help
Vehicles manufactured after 1996 are equipped with On-Board Diagnostics (OBD-II). This system monitors critical engine and emissions components. When an issue is detected:
- A trouble code is recorded in the vehicle’s computer
- The Check Engine light illuminates
- Diagnostic tools can read these codes to determine the source of the problem
At 8 Cylinders Auto Repair, we use professional-grade OBD-II scanners to retrieve codes and generate a detailed diagnostic report, allowing us to efficiently target the repair.

A flashing Check Engine light indicates an urgent problem; stop driving and have your vehicle inspected immediately.
