Review on 🚀 LAUNCH Millennium 40 OBD2 Scanner: Your DIY Universal Car Code Reader for Fault Code Diagnostic Scan Tool, Check Engine Light, I/M Readiness, DTC Lookup & Vehicle Info – Free Lifetime Update! by Scott Gafur

This tool is definitely easy to use. Just plug in and get started. I've had a check engine fault in my car for a long time and I know it's the sensor which isn't a big deal (my mechanic told me I can live with it) but I can't clear the C/E's until I fix it, so sometimes I wonder if I have another problem. This tool has confirmed that I only have one DTC (Diagnostic Trouble Code) for this sensor, so I know it got it right and I know I have no further questions. I'll be using it regularly to make sure the C/E light isn't meant for something else.
