Helpful answers
Check Engine Light
questions.
Is a free code scan the same as a diagnosis?+
No. A code scan is useful information, but proper diagnosis determines why the code set and which repair is justified.
Can I drive with the check engine light on?+
A steady light may allow cautious driving, but it should be checked soon. A flashing light often indicates a damaging misfire—reduce load, stop when safe and arrange service.
Why did my check engine light return after parts were replaced?+
The original fault may not have been confirmed, more than one issue may exist, or the system may need further testing.
