What Your Check Engine Light Is Telling You
Your vehicle's computer watches the engine, emissions and fuel systems constantly. When a reading falls outside its normal range, it stores a diagnostic trouble code and turns on the light.
A steady light usually means the vehicle has detected a fault that should be checked soon. It is generally fine to drive to a service appointment, though you should watch for changes in how the vehicle runs.
A flashing light usually signals an active misfire that can overheat and damage the catalytic converter. Reduce speed, avoid hard acceleration, and get the vehicle looked at as soon as possible. If it runs very poorly, call us at 503-777-2886 before driving further.
Drivability Problems Worth Diagnosing
Plenty of engine concerns show up before, or without, a warning light. Bring the vehicle in if you notice:
- Rough idle, shaking or stumbling at stops
- Hesitation, surging or loss of power when accelerating
- Hard starting or stalling
- A noticeable drop in fuel economy
- A smell of fuel, a sulfur smell, or unusual exhaust smoke
- Other warning lights that come on together with the check engine light
How Engine Diagnostics Work
A trouble code points to a system, not always to a single bad part. A code for a lean condition, for example, could come from a vacuum leak, a sensor or a fuel delivery issue. Here is how a diagnostic visit goes:
- Share the detailsTell the advisor when the light came on, whether it is steady or flashing, and anything you have noticed in how the vehicle drives.
- Read codes and testA technician retrieves stored codes and data, then tests the related components to confirm the cause.
- Explain the findingsYou get an explanation of what was found and the recommended repair, so you can decide how to proceed.
A parts store code reading can be a useful starting point. It is not the same as a diagnosis, because a code alone does not confirm which part failed.

Check Engine Light FAQs
Can I keep driving with my check engine light on?
If the light is steady and the vehicle drives normally, it is usually fine to drive to a service appointment soon. If the light is flashing or the vehicle runs poorly, reduce driving and call 503-777-2886 for advice.
Why is my check engine light flashing?
A flashing check engine light usually indicates an active engine misfire. Continued hard driving can overheat the catalytic converter, so have the vehicle checked as soon as possible.
Can a loose gas cap turn on the check engine light?
Yes. A loose or worn gas cap can trigger an evaporative emissions code. If tightening the cap does not clear the light after some driving, have the vehicle diagnosed.
Is reading the code the same as a diagnosis?
No. A trouble code points to a system or condition. Diagnosis means testing to confirm which component or condition is causing it.
Do you diagnose vehicles that are not Mitsubishi?
Yes. Roger Kehdi Mitsubishi services all makes and models, including engine diagnostics.
Do I need an appointment for a check engine light?
Walk-ins are welcome during service hours. You can also schedule service online or call 503-777-2886.
