My husband has had a Check Engine light coming up and dinging on his car for years. He is an experienced and successful maintainer of cars; there was no malfunction of his car, and the owners manual had no suggestions except, Bring in for Service.Not happening. This little critter diagnosed the issue (bad sensor) as soon as it was plugged in. He thinks it was worth every penny.
