Professional Check Engine Light Diagnostics


Warranty | Joyce Automotive and Towing

Advanced OBD-II System Analysis

Modern vehicles use sophisticated onboard diagnostic systems (OBD-II) that monitor engine performance, emissions output, and hundreds of other parameters. When the system detects an irregularity, your check engine light activates. Our advanced diagnostic scanners can retrieve and interpret these trouble codes, providing detailed information about what's causing the warning.



Comprehensive Engine System Inspection

A glowing check engine light can indicate anything from a loose gas cap to serious engine problems. Our diagnostic process goes beyond simply reading codes – we perform thorough inspections of all related systems to identify the true source of the issue and any additional problems that may need attention.


Expert Code Interpretation and Testing

Diagnostic trouble codes provide valuable clues, but they don't always tell the complete story. Our ASE-certified technicians use their experience and additional testing procedures to verify the actual cause of the problem, ensuring we address the root issue rather than just the symptoms.

Our Check Engine Light Diagnostic Process


Initial Vehicle Assessment and Code Reading

When you bring your vehicle to Joyce Automotive & Towing for check engine light service, we begin with a complete system scan using professional-grade diagnostic equipment. This retrieves all stored trouble codes and provides baseline information about your vehicle's current status.



Detailed System Testing and Verification

After identifying potential issues through diagnostic codes, our technicians perform targeted tests on specific components and systems. This might include checking oxygen sensors, catalytic converter efficiency, fuel injection systems, or emissions control components, depending on the codes retrieved.


Clear Explanation and Repair Options

We believe in transparent communication throughout the diagnostic process. Once we've identified the problem, we'll explain our findings in terms you can understand and provide detailed estimates for any necessary repairs. We never perform work without your approval.


Professional Repair and System Verification

All check engine light repairs are completed using quality parts and manufacturer-approved procedures. After repairs, we clear the codes and perform additional testing to ensure the problem is fully resolved and your vehicle's systems are functioning properly.

Common Check Engine Light Causes We Address


Emissions System Problems

Issues with oxygen sensors, catalytic converters, or evaporative emission control systems are among the most common causes of check engine lights. These problems can affect fuel economy and emissions output if left unaddressed.



Fuel System Issues

Faulty fuel injectors, fuel pumps, or fuel pressure regulators can trigger check engine lights while affecting engine performance. Our diagnostic equipment can pinpoint these issues quickly and accurately.


Ignition System Malfunctions

Problems with spark plugs, ignition coils, or related components can cause misfires and trigger check engine warnings. These issues often worsen over time and can lead to more expensive repairs if ignored.


Engine Management Sensor Failures

Modern engines rely on numerous sensors to monitor performance and adjust operation. When these sensors fail or provide incorrect readings, the check engine light activates to alert you to the problem.
