No problems with the car for over a year but the check engine light was on. My husband drove his car to an auto parts store and the clerk plugged in his scanner and the codes that came up weren't serious, but he didn't turn off the check engine light. We ordered this scanner because we saw it being used on You Tube and we were still days away from outlier testing. We hooked up the scanner, followed the instructions, cleared the engine gauge and passed the emissions test. A month has passed before the engine light comes on.
