A code is a starting point, not an answer. When that light comes on, the computer has seen a reading outside the range it expects and stored a code for it. The code names the system involved. It doesn't name the broken part. One code can have five believable causes sitting behind it, and the only honest way to tell them apart is to test.
Steady or flashing matters. A steady light means the computer wants someone to look at it, and you can usually finish your errands and get it scheduled. A flashing light means the engine is misfiring right now and unburned fuel is heading into the exhaust. If it is flashing, pull over when it is safe and have the car towed or looked at before you drive it further.
Diagnosis starts with every stored code plus the freeze frame data that came with it, so we can see what the engine was doing at the moment the light triggered. Then we watch live data with the engine running. Fuel trims show whether the computer is adding or pulling fuel to cover for something. Sensor readings get compared against what the engine is actually doing. From there our ASE certified techs test the specific suspects, which is how a failing sensor gets separated from a vacuum leak or a wiring problem instead of replacing parts in order until the light goes out.
Some codes have nothing to do with how the car drives. Evaporative emissions codes are the usual example: the car feels perfectly normal while fuel vapor quietly leaks away. Sometimes it really is a loose or worn gas cap, and we'll tell you that. Often the cap is fine and a smoke test finds the leak somewhere else in the fuel vapor system.
You leave knowing the actual cause, with inspection photos on your phone and a written quote. Whether you fix it that day is a separate decision.
The technician retested and verified the repair, and performed a final road test where applicable.

New to the area, so after reading Google reviews, i went to Johnny's with some dashboard lights on. They were very courteous and friendly and once they ran the diagnostic tests explained the issues that were found. The waiting room is comfortable, clean and well stocked. They sent me home and when my car was ready the next day they had me picked up. My car is running like new. Will not hesitate returning for any other issues that may pop up and I highly recommend their service. Update. Back for regular service and maintenance, including new tires. Still very impressed with this business and everyone I have encountered there. Will continue to go there for anything and everything associated with my vehicle, as they have my full trust.

They will fix it right! Had a check engine light for my transmission and they fixed it and it has never came back since. Good reliable service. They also treat your car as one of their own with the utmost care and respect ^-^

I was dealing with a big problem on my 2007 Chevy Suburban with 431,820 miles. It was idling rough with a misfire (lean code on bank 2), and Johnny’s took the time to find out the source of a three month ordeal. You guys totally ROCK! My car is running better then ever, and no check engine light. The team at Johnny’s is very friendly, responsive, upfront, thorough, and honest. Genuinely excited to bring my car back to them next time it hiccups. From start to finish 100% satisfied.

I’m really happy that I chose to come here! I recently moved to the area and came in due to a check engine light. As a young girl it can be intimidating going to a mechanic. Their team made me feel comfortable and didn’t try to recommend a bunch of additional services. Mike took the time to explain the issue to me and had kept me updated on when my parts arrived! The waiting area was very comfortable and the gentleman that shuttled me home and back seemed really kind. I’m so glad I found a place that makes me feel comfortable and like a priority! I will definitely recommend this place if anyone asks!
