When your check engine light appears, we use advanced diagnostic tools to pinpoint the issue and prevent bigger problems down the road.
Our diagnostics and check engine light FAQs help Machesney Park drivers understand warning lights, testing procedures, and when professional inspection is needed to keep their vehicle running safely and efficiently.
A check engine light can indicate anything from a minor issue like a loose gas cap to more serious problems with the engine, emissions, or sensors. A professional diagnostic scan is the only way to know for sure.
If the light is steady, you may be able to drive short distances, but the issue should be diagnosed as soon as possible. If the light is flashing, stop driving and have your vehicle inspected immediately to avoid engine damage.
Our technicians connect professional diagnostic equipment to your vehicle to retrieve trouble codes, analyze system data, and perform inspections to accurately identify the root cause of the issue.
Sometimes the light may turn off temporarily, but that doesn’t mean the problem is resolved. Stored codes can remain, and the issue may return if not properly diagnosed and repaired.
Diagnostics identify where the problem is occurring, but additional testing may be needed to confirm the exact repair. We explain findings clearly before recommending any work.
Basic diagnostics can often be completed the same day. More complex electrical or intermittent issues may require additional testing time, which we’ll communicate upfront.
