How much does check engine light diagnosis cost?

Diagnostic fees at Pinnacle Motorsports start at $89-129 depending on vehicle complexity. This fee is applied toward the repair cost if you choose to have us fix the issue. We never charge just to plug in a scanner — we provide a thorough diagnosis.

Can I drive with a check engine light on?

A steady check engine light usually means you can drive safely to our shop for diagnosis. However, a flashing check engine light indicates an active misfire that can damage your catalytic converter — pull over safely and call us.

Why did my check engine light come back after repair?

If a check engine light returns, it could be a related but different issue, an intermittent fault that wasn't fully resolved, or a secondary problem masked by the original code. We stand behind our diagnoses and will re-evaluate at no additional diagnostic charge.
