(Pt2) Crazy Honda STUMPS Dealer...Runs RICH Once a MONTH?? ('17 Accord V6: P0175-P0297-P0299)

In Part 1 we found a slightly "Elevated" Ground on the MAF sensor, causing a "skewed-High" MAF reading, and NEGATIVE Fuel Trims on this MINT 2017 Accord V6 with only 40k miles.

A "Hot Soak" seems to make the problem worse.

So WHY is the MAF Ground going up to 200mV?

Is it a Wiring Problem? Connector Problem? PCM Problem?

Let's perform a very precise Voltage Drop Experiment by loading the MAF Ground with a 90mA test light. The results will BLOW YOUR MIND!

Finally, can we get this Accord V6 Repaired NO PARTS REQUIRED?
