Check Engine Light Diagnostics

Welcome to Affordable Auto Repair

A check engine light can mean anything from a loose gas cap to a serious engine problem. At Affordable Auto Repair, we take the guesswork out of that warning light with accurate, professional diagnostics.

Our certified technicians use state-of-the-art diagnostic equipment to read your vehicle's onboard computer and identify exactly what triggered the light. We explain what we find in plain language and give you an honest recommendation before any repair work begins.

Our check engine diagnostics include

• Computerized Engine Scans

  We connect your vehicle to advanced diagnostic scanners to pull trouble codes directly from the engine control module, giving us an accurate starting point for every diagnosis.

• Sensor and Emissions Testing

  Faulty oxygen sensors, mass airflow sensors, and emissions components are common causes of check engine lights. We test each one to confirm the true source of the problem.

• Misfire and Ignition Diagnostics

  Rough idling or engine misfires often trace back to spark plugs, ignition coils, or fuel delivery issues. We isolate the cause so repairs target the real problem, not just the symptom.

• Clear, Honest Explanations

  We walk you through exactly what the diagnostic scan found, what it means for your vehicle, and what your repair options are, so you can make an informed decision.

• Light Reset and Verification

  Once repairs are complete, we clear the code and verify the check engine light stays off with a post-repair test drive and follow-up scan.
