Review on 🔌 Friencity Wireless OBD2 Scanner Adapter for Android & Windows - Bluetooth Diagnostic Code Reader, Reset & Clear Car Engine Light, Supports Torque Lite App, Not Compatible with iOS by Roberto Strumer

This ObdII should be used to crank the engine, not just start it. I thought it was a marriage but when I started the engine it worked fine. You can download the torque app for free and you will receive a code that you can delete. Use this to get the code, study the code, watch youtube how to fix it. Then repair, delete code, done. I used to fix the 02 sensor, then I had to change another problem with the air intake. Going to the mechanic would cost me 150 for diagnosis (each time), then about 300 for each repair. I paid 80 for one and 30 for the other. Installing both parts took less than 15 minutes. It's worth your money and time.
