When You Need This
The Check Engine Light is your car’s way of saying something isn’t right. Diagnosis helps catch issues early, before they become costly or unsafe.
Steady or Flashing Check Engine Light
Any warning light on the dashboard needs prompt attention to avoid further damage.
Poor Fuel Economy or Performance
A malfunctioning sensor or ignition component can cause decreased power and efficiency.
Rough Idle or Stalling
Misfires or air-fuel ratio problems can make your engine run unevenly.
After a Recent Repair or Long Trip
Even small issues can trigger the light — especially after battery changes, refueling, or extended highway driving.

⚠️ What happens if you skip it? ⚠️
Ignoring the Check Engine Light can allow minor issues to worsen, reduce fuel efficiency, and even damage expensive components like the catalytic converter. Early diagnosis saves money and prevents breakdowns.
What It Could Be
The Check Engine Light can appear for dozens of reasons — some minor, some critical. Common causes include:
• Loose or Faulty Gas Cap
A simple issue that can trigger the light after refueling.
• Oxygen or Mass Airflow Sensor Failure
Affects how the engine manages air and fuel mixture.
• Catalytic Converter Efficiency Issue
Often related to age, fuel quality, or exhaust restriction.
• Ignition System Misfire
Worn spark plugs or coils can cause misfires and poor acceleration.
• Emission or EVAP System Fault
Leaks or sensor errors in the evaporative emissions system.
How This is Done
We combine factory-grade scan tools with technician expertise to locate the problem quickly and accurately.
• Scan the Vehicle’s Computer
Retrieve stored and pending fault codes from the engine control module.
• Review Live Data
Monitor real-time sensor readings and system behavior.
• Perform Visual and Functional Checks
Inspect related wiring, connectors, and components.
• Test and Verify
Run system tests or short drives to confirm the root cause.
• Explain Findings
Review results and provide clear, honest repair recommendations.
Is the diagnostic really free?
Yes — if you approve the recommended repair or service, we waive the $100 diagnostic fee.
What does a Check Engine Light mean?
When your check engine light is on, it can mean a variety of things. In general, if the light is flashing, it can be a serious issue so you should take your car to a trusted mechanic immediately. If the light is on but not flashing, it is likely a less serious issue, but you can still cause further damage by driving the car. A Roda mechanic may be able to diagnose the issue with a quick visual inspection (done free of charge!). If not then a diagnosis will be required in order to determine why the light is on.
Can I keep driving with the Check Engine Light on?
It depends. A flashing light means an active misfire — stop driving and have it checked immediately. A steady light indicates a less urgent issue, but it should still be diagnosed soon.
Will you clear the code after diagnosis?
Yes, but only after confirming the issue is resolved. Clearing codes without fixing the cause can hide problems temporarily.
What happens if I decline the repair?
A $100 diagnostic fee applies to cover technician time and testing.
What does the Roda warranty cover?
All repairs performed after diagnosis are covered by our Roda 12-month / 12,000-mile warranty, including both parts and labor for complete peace of mind.
