MAP Sensor replaced on my 2013 Chevy Express 3500
My 2013 Chevy Express was throwing a couple codes that indicated that it was running rich.
During diagnostic testing, I noticed that the MAP sensor was malfunctioning. I couldn't find a video that showed me exactly where it was or how to replace it, so I made one.
In addition to the MAP sensor, my fuel composition was showing that it was high in alcohol (ethanol), but I had only been running 87 octane unleaded (less that 10% ethanol). I took it to a local shop and the mechanic didn't even charge me to reset the fuel composition.
Hope this helps someone.
Thanks for watching!
