Review on 🔌 ANCEL BD310 OBD2 Scanner: Check Engine & Battery Voltage, 2-in-1 Wired Handheld & Bluetooth App with Real-time Monitor by Mike Palma

The perfect tool for DIY enthusiasts. Read codes, erase codes. You can monitor engine coolant temperature, engine controls, fuel trim, O2 sensors, speed sensor, RPM and intake air temperature. You can also check and test the vaporizer system. You can use a handheld device or connect it to your phone. Bluetooth looks better and is a bit easier to bypass, but is a little slower to respond, but it's not bad. I like using the device because then I can do whatever I want with my phone. I used it to compare the computer's engine temperature to an aftermarket sensor I installed. It turns out that my meter reads about 8 degrees higher than the computer. So when I thought my engine was hot, it really wasn't.
