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..

I am not responsible if you try to duplicate something I do and damage your property or injure yourself. Please do your own research on proper methods or hire a professional.

This is a great video. I wish it had seen it while i was starting as a tech. Really valuable information of covering the basics and troubleshooting. Specialy since cars with this type of fuel system the air filter needs to be clean and cant tell you all the times at first my butt was beat because of a dirty filter when i was starting troubleshooting. Cant wait for the rest. Of the sensors and if you can do another series about DTC criteria it really helps out to understand what test the computer uses to throw codes. KEEP UP THE GOOD WORK!!!

Would a dirty or faulty MAF cause a P0296 code? It's a lean bank 1 down from the cat
