Question: Is air supposed to be allowed to pass from the unplugged port with a hose(like in the test photo character) with the other port plugged and vacuum applied to the bottom port?

Yes or No?

I don't know how much pressure 0.981 kPa is, but it sounds like if you put that pressure on the bottom, plug a top port and suck on one of the other, you should not be able to suck in any air.

It’s what I was thinking as well...

No leakage from the diaphragm with applied pressure from the bottom port. With applied pressure, the diaphragm is lifted up and the bottom air passage is blocked. DTC P0402’s drawing shows this.

With no applied pressure to the bottom port underneath the valve. The BPT valve’s diaphragm isn’t lifted up. Therefore, with one top port plugged/blocked and vacuum applied to the other top port that’s open. Leakage should exist. DTC P0402’s drawing also shows this.

0.981 kPa is a very low amount of pressure. It’s the back pressure transducer, BPT, which controls vacuum from the throttle body and the amount of exhaust gases from the exhaust manifold tube into the EGR system.

Thanks JP!

Hahahahaha!

In the words of Lt. Colonel Oliver North, “I have no recollection “.

I’ve edited my post for a better interpretation of the BPT test.

Edit - BPT has failed the component test with no vacuum pressure applied to the bottom diaphragm port. Diaphragm was leaking air quite rapidly on the MityVac gauge pumped to 15 kPa. New BPT valve ordered through Courtesy Nissan of TX.

Compared my D21 to a 2021/2022 Ford Maverick Hybrid “truck”.

This “truck” actually belongs to a coworker of mine.

The maverick ain't a truck. It's a minivan with part of the roof cut off. Same as a Ridgeline.

LOL

I've always thought the Ridgeline was a dumb-looking vehicle.

They're very similar. The Ridgeline is basically a Honda Pilot with a bed instead of a third row seat, and the pilot/MDX are in turn an Odyssey with a lift and AWD. They're not bad vehicles but they're not meant for towing or moving anything heavy. I cringe whenever I see one towing a camper. Honda makes a great V6 but their transmissions aren't up to the task.

The pilot/MDX used to not be directly minivan related. Kinda like how the pathfinder used to actually be a truck, not a minivan.



I've heard the Ridgeline is very comfortable which I would expect from the minivan lineage.





The Ridgeline isn't as dumb looking as the new tundra. What a god awful and hideous vehicle. It's got that Lexus grill too where the entire front of the vehicle is a grill. It's stupid.





My truck has been putting in a little work lately. Moving pallet jacks and cherry pickers along with some Ford excursion leafs. Those things are HUGE!
