Common Engine Diagnostics Issues We Fix
Modern vehicles rely on complex computer systems to monitor engine performance. When something goes wrong, your check engine light illuminates, signaling potential issues. At Josh Hawkins Automotive in Gresham, we use professional-grade diagnostic equipment to quickly identify the root cause and recommend the right repairs.
Check Engine Light
Diagnostic trouble codes indicating sensor failures, emissions issues, or engine malfunctions.
Oxygen Sensor Failures

Mass Airflow Sensor Issues
Dirty or failed MAF sensors causing rough idle and performance problems.
Catalytic Converter Problems
Failed converters reducing engine power and triggering check engine lights.
Ignition System Faults
Bad spark plugs, coils, or wires causing misfires and rough running.
Fuel System Problems
Fuel pump failures, clogged injectors, or pressure regulator issues.

Our Engine Diagnostics Process
Our systematic diagnostic approach combines advanced technology with experienced troubleshooting to accurately identify engine problems and recommend the most cost-effective solutions.
Initial Consultation
We start by discussing the symptoms you've noticed—unusual noises, warning lights, performance issues, or driveability concerns. Understanding when problems occur helps us focus our diagnostic efforts on the most likely causes.
Computer Scanning
Using professional-grade scan tools, we connect to your vehicle's onboard computer to retrieve diagnostic trouble codes (DTCs). We analyze both current and pending codes, review freeze frame data, and check live sensor readings to understand what the computer is reporting.
Physical Inspection
Beyond computer codes, we perform hands-on inspection of suspected components. We check for vacuum leaks, examine wiring connections, inspect sensors and actuators, and verify mechanical operation. This physical inspection often reveals issues that don't trigger codes.
System Testing
We perform targeted tests on specific systems based on our findings. This may include compression testing, fuel pressure checks, ignition system analysis, emissions testing, or electrical circuit diagnosis. Each test provides critical data to pinpoint the exact problem.
Detailed Report & Recommendations
Once we've identified the problem, we provide a clear explanation of what's wrong, why it happened, and what needs to be repaired. We present repair options with transparent pricing, helping you make an informed decision about your vehicle's care.

FAQs About Engine Diagnostics in Gresham
What does a check engine light mean?
A check engine light indicates your vehicle's computer has detected a problem affecting emissions, engine performance, or drivability. The specific issue is stored as a diagnostic code that we retrieve during testing. Ignoring it can lead to more expensive repairs or damage.
How long does engine diagnostics take?
Basic diagnostic scans typically take 30-60 minutes. Complex problems requiring extensive testing may take longer. We'll provide a time estimate once we understand your vehicle's symptoms and communicate updates throughout the diagnostic process.
Is it safe to drive with the check engine light on?
It depends on the issue. A steady light often means you can drive carefully to our shop. A flashing check engine light indicates a serious problem like engine misfires—pull over safely and call for a tow. We can advise you based on your symptoms at 903-871-3951.
What's included in your diagnostic service?
Our diagnostics include computer scanning, code interpretation, physical inspection of related components, system testing, and a detailed explanation of findings. We identify the root cause—not just the code—and provide repair recommendations with transparent pricing.
Can I just clear the codes myself?
While you can clear codes with a basic scanner, the light will return if the underlying problem isn't fixed. Professional diagnostics identify why the code appeared, allowing proper repairs. This prevents recurring issues and potential damage from ignored problems.
Do you work on all vehicle makes and models?
Yes! We have the equipment and expertise to diagnose domestic and foreign vehicles including cars, trucks, and SUVs. Our scan tools work with all major manufacturers, and our technicians stay current with evolving automotive technology.
