VOTED BOULDER'S TOP AUTO REPAIR BY CARFAX — 2024 & 2025

Check Engine Control Light on a Vehicle Dashboard

The “Check Engine” warning light or “Service Engine” notification, often represented by a small engine-shaped icon, is your car’s way of telling you that something isn’t quite right under the hood. While it doesn’t always indicate a catastrophic issue, it’s essential not to ignore it.

At HTC Auto Repair Shop, we understand the importance of promptly diagnosing and resolving these issues to ensure the continued performance and reliability of your vehicle. Allow us to service your car’s engine and perform engine diagnostics the next time your vehicle’s engine light turns on.

Why the check engine light comes on

The check engine light is part of your car’s onboard diagnostics system. It alerts you when the system detects a problem with engine performance, fuel efficiency, or vehicle emissions. This light can appear as a steady glow or a flashing warning light. A steady light often indicates a minor problem that should be checked soon, while a flashing engine light may signal a more serious issue that needs attention immediately.

HTC Check Engine Light Services Include:

Comprehensive Engine Diagnostics:

Our experienced mechanics use advanced engine diagnostic equipment to retrieve trouble codes stored in your vehicle’s onboard computer system. Our engine diagnostics include a thorough inspection of the engine performance, spark plugs, monitor vehicle emissions, and other relevant components to pinpoint the underlying cause of the Check Engine Light.

Troubleshooting and Analysis:

Once the trouble codes have been retrieved through your engine diagnostics, our team conducts further troubleshooting and analysis to determine the root cause of the issue. We examine sensor readings, spark plug wires, ignition coil, air filter, engine parameters, and other data to accurately diagnose the problem.

Check Engine Light/Service Engine Reset:

After identifying and addressing the underlying issue, our mechanics will reset the Check Engine Light and clear any stored trouble codes from your vehicle’s computer system. This ensures that the light is properly reset and will only illuminate again if a new issue arises.

Emissions System Repair:

Many issues that trigger check engine lights are related to the emissions system, including oxygen sensor failures, old fuel filter, catalytic converter issues, and evaporative emissions leaks.

Our team has the expertise to perform engine diagnostics and repair emissions-related problems to ensure compliance with environmental regulations and optimal engine performance.

Engine Component Repair:

In some cases, the Check Engine Light may indicate problems with specific engine components, such as the ignition system, fuel system, or engine sensors. Our mechanics are equipped to repair or replace faulty components to restore proper engine operation and performance.

Common reasons for an engine light

  • Loose gas cap: One of the simplest problems that can trigger the light.
  • Faulty ignition coil or spark plug wires: Issues in the ignition system can affect performance.
  • Worn spark plugs: These small parts have a big effect on fuel economy and how the engine runs.
  • Clogged fuel filter or dirty air filter: Problems with the fuel system or airflow can hurt engine performance.
  • Transmission issues: Sometimes the light can be connected to shifting or transmission functions.
  • Failing oxygen sensors: Important for monitoring fuel and emissions.

These are only some of the reasons why the light may come on. A thorough inspection with professional engine diagnostics is the best way to identify the exact cause.
