You gota slid out the dishwasher from under the counter an lay it down the pump is at the bottom. Disconect the drain hose before you pull it out. Depending on if the guy that installed it was a dick or not he might have left enough wire so you can pull out with out disconnecting the wires. Just put the breaker to off. It will spill water so be ready for that. When you open the door look along the side, inside the dishwasher you will probably find atleast 2 small rubber plugs. Pull em out there will be screws that you need to remove. They keep the dishwasher in place by screwing into cabinet on each side. The pump typically just twists off might have a lock tab that needs to be pried up.

Have you removed the drain pump yet? Chances are there is a piece of bone, glass, cherry pit, crayon, zip tie, bread tag logged in there.

Not gona lie seems awfully inconvenient in light rain shower.

Look mommy it’s snowing.

If you look up dtc for mass air flow sensors you can see from their failure modes what the ecm input is supposed to be P0102 and P0103

Sorry, typically from what I remember. The third wire is typically the signal wire. You get the 12v in then ground and the 3rd wire the ecm will read the signal via voltage drop usually.

This is more of a personal curiosity rather than helping you.

From what I can make sense, the way this thing would work is by heating up an element. The air flow will cool the element, and the ECM measures the current needed to keep the element at a pre-set temperature.

Would that be correct?

Look every one, we have a fucking retard amongst us.
