Common Check Engine Light Causes We Diagnose
Oxygen Sensor Malfunctions
Faulty oxygen sensors are among the most common causes of check engine lights. These sensors monitor exhaust gases to optimize fuel mixture, and failure can affect fuel economy and emissions compliance.
Catalytic Converter Issues
Catalytic converter problems often result from underlying engine issues or normal wear over time. Our diagnostics identify whether converter replacement is necessary or if upstream repairs can restore proper function.
Mass Airflow Sensor Problems
Contaminated or failing mass airflow sensors disrupt the air-fuel mixture, causing poor performance and check engine light activation. Colorado's dusty conditions can accelerate sensor contamination.
Ignition System Failures
Worn spark plugs, faulty ignition coils, or damaged wiring can trigger check engine lights while causing misfires, rough idle, and reduced fuel economy. Our diagnostics pinpoint specific ignition system components requiring attention.
EVAP System Leaks
The evaporative emissions control system prevents fuel vapor release into the atmosphere. Small leaks in this system commonly trigger check engine lights and require specialized diagnostic equipment to locate.
