What is the Check Engine Light?

Your vehicle’s check engine light is part of its onboard diagnostics (OBD) system, designed to monitor engine and emissions performance. When the check engine light illuminates, it means the system has detected a potential problem in your engine, emissions system, or other critical components. This warning light can range from a simple issue, like a loose gas cap, to something more complex, like an exhaust or electrical fault.

Understanding and Responding to Check Engine Light Signals

The check engine light can signal various issues, each requiring timely attention:

  • Solid Light: Indicates a less urgent issue, like a sensor or minor emissions problem, but still needs checking.
  • Flashing Light: Warns of a serious issue, such as an engine misfire, which could cause damage if ignored. This needs immediate attention.
  • Intermittent Light: If the light comes on and off, it may suggest a developing issue or loose connection; it’s best to schedule a check promptly.

Scheduling a diagnostic as soon as the light appears helps prevent costly repairs and keeps your vehicle safe and efficient, especially if there are additional symptoms like unusual sounds or reduced performance.

Our Complete Check Engine Light Services

Our check engine light services provide complete diagnostics and repairs to keep your vehicle running smoothly. With dealership-level OEM tools, we accurately pinpoint and resolve issues. Here’s what our diagnostics and testing cover:

Comprehensive Engine Diagnostics

Our expert technicians utilize OEM scan tools to conduct a thorough engine diagnostic. We’ll access trouble codes, assess the issue, and provide a clear explanation of what’s causing the warning light.

Electrical Diagnostics

Many check engine light issues stem from electrical faults within sensors, wiring, or the vehicle’s computer systems. Our electrical diagnostics identify faults with precision, from ignition systems to the fuel injectors.

Emissions System Testing

The emissions system is one of the most common causes of a check engine light. We test components like the catalytic converter, oxygen sensors, and the exhaust gas recirculation (EGR) system, making necessary repairs to keep your vehicle emissions compliant.

Fuel System Inspection

Fuel-related issues, like a faulty fuel cap, fuel injector issues, or an inefficient fuel pump, can cause the check engine light to illuminate. We inspect the entire fuel system to pinpoint and resolve issues that affect your vehicle’s performance and fuel economy.

Transmission Diagnostics

Transmission issues can also activate the check engine light. Our team conducts thorough transmission diagnostics, addressing shifting issues, sensor malfunctions, and fluid levels to ensure smooth operation.

Sensor and Module Testing

Modern vehicles rely on various sensors to monitor engine performance and emissions. We test and calibrate essential sensors, including the oxygen sensor, mass airflow sensor, and more, ensuring accurate data is fed to your vehicle’s main computer.

Ignition System Testing

A faulty ignition coil or spark plug can cause misfires, leading to a flashing check engine light. Our team inspects the ignition system to ensure all components are functioning properly, preventing further engine damage.
