Works perfectly, it’s quick and responsive. Very intuitive and with a little studying you can understand the advanced functions. Will easily fit in your glove box (you never know when you’ll be on the side of the road so keep it in there) It told me the issue, I replaced the sensor and cleared the code. Saves a ton of time.
