READING OBD2 LIVE DATA SERIES:

The OBD2 Sensor Series is going to be a series of videos going over each automotive sensor showing both how it works and how to test and diagnose issues using an OBD2 scanner. I will also try to use generic OBD2 scanners that are cheaply available like Veepeak, Amtifo, Foxwell, Thinkcar etc..

Great video, like the explanation. There is a cool test with the ECT you can use it to test a engine thermostat with the live data of the ECT. Most cars have electric thermostat and helps with diagnosis. I would like to see a part to showing this quick test.

My obd2 show on cold start temp like 10degree (like outside) up to 26 degrees about every second by 1 .
Like( from 10 to 25 ) for 15 seconds and then start normal .
And close loop on 13 ? What this
mean ? 🤖

My 10th generation honda civic randomly drops the temperature to 0 bars. If i restart the car it acts like it is in close loop cold start mode. Also it is fixed randomly while driving.
Can somebody help me diagnose this as nobody in Pakistan is able to detect where the problem is.

Mine showing -30°C and not rising nor decrease. But in the dash, Its moving and when I drove it around for a moment. Its rising up in the middle, maybe about 100°C. I don't know whats wrong with it, is it my scann tool is bad or my ECT is bad.
