What Could It Be?

A check engine light can be triggered by several potential issues. Let our ASE-certified technicians perform engine diagnostics on your vehicle to make an accurate diagnosis. Here are some common problems:

• Failing Sensors: A faulty oxygen sensor can lead to poor fuel economy and potential damage to the catalytic converter. Regular checks help maintain engine performance.
• Mass Airflow Sensor: This sensor manages the fuel-to-air ratio in your engine. Replacing a malfunctioning sensor can improve your vehicle’s performance.
• Catalytic Converter: Essential for reducing emissions, this component must function properly for your car to pass emissions tests.
• Loose Gas Cap: A poorly fitting gas cap can trigger the check engine light and cause fuel evaporation. It’s an easy, affordable fix.
• Battery or Charging System Issues: Problems with your battery or charging system can activate the check engine light. Proper diagnostics will reveal the underlying cause.
• Ignition Coil Problems: A failing ignition coil can disrupt your engine’s firing and cause performance issues. Early detection can prevent further damage.
• Transmission Issues: Early signs of transmission trouble may also trigger the check engine light. It’s important to address these issues quickly.

Bring your vehicle to our shop for a thorough diagnosis. Our ASE-certified technicians will use state-of-the-art diagnostic tools to pinpoint the root cause and provide the appropriate engine repair services.

Our Check Engine Light Diagnostic Process

When you bring your vehicle in for a check engine light issue, we start by asking about recent performance issues, unusual sounds, or any changes in your car’s engine behavior. Our team also checks the vehicle’s dashboard lights and may take it for a short drive to better understand what’s happening.

Next, our experienced technicians use a scan tool to retrieve trouble codes from your car’s engine control module. From there, we perform a targeted inspection—looking at parts like the ignition system, fuel system, and spark plugs—to pinpoint the root cause before recommending the necessary repairs.

Cracking Diagnostic Trouble Codes With Ease

Once your check engine light comes on, the next step is reading the diagnostic trouble codes (DTCs) your vehicle’s onboard computer stores. Using a scan tool connected to your car’s OBD-II port, our Import Auto Repair team retrieves these codes to determine where the issue may be hiding.

DTCs are five-character alphanumeric codes that fall into four main categories: Powertrain (P) for engine and transmission issues, Body (B) for parts like airbags and climate control, Chassis (C) for steering and suspension, and Network Communication (U) for system communication errors. These codes are then further sorted into generic codes (universal across all manufacturers, shown with a “0” as the second digit, like P0300) and enhanced codes (specific to certain manufacturers, shown with a “1,” like P1401). Our experienced technicians are highly skilled at interpreting these codes and using them to accurately diagnose engine problems, so you can trust Import Auto Repair to get to the root of the issue quickly and professionally.
