You learned to bench test any part that’s difficult to install. All you friends, acquaintances and acquaintances of acquaintances have learned who to call when they’ve got a problem. 😜 Interesting video, thanks!
I've helped a lot of people the criteria I follow is whether the recipient seems to help others at times...and if it's not much skin off my back but helps the recipient a great deal, then I'll step forward
It would be interesting for Rock Auto to see this video, and test the resistance of all of the SKP EGR valves for this Jeep that they have in stock, to see how many have the wrong resistance, it is all of them (design/build completely wrong) or some percentage (quality control issue).
I agree, changing those valves will make a grown man cry. I have had lots of issues with Dorman EGR valves on Caravans lasting weeks to months. Warranty them out, and same problem. Finally insist on OEM valve and problem solved.
Frustrating dealing with aftermarket parts…Does it matter (within reason) what the R value of the feedback sensor is, if it’s only acting as a voltage divider. Mid point is -2.5V ish no matter what…Right? (Assuming it’s on a 5V ref line). Dunno. Sorry for your trying circumstances Denis, but with your tenacity I think it ended well. 👍🍻
R value might matter Ian ... PCM outputs a bias voltage on signal wire(wasn't expecting it and easily pulled down with a test light)...and if PCM doesn't like what it sees, it locks up into that 4.3v substituted value ... not 100% sure
@@TheGibby3340 not the 5v REF ... but on the SIGNAL wire output from PCM ... it also has 5v (just a bias, easily pulled down) was new to me and researched it...turns out it's a thing a bit like bias voltage on tail lights system...will have indicator on instrument panel if tail light bulb is burned (or if low resistance LED bulb was put in) the 200Ω on the Chinese EGR might be enough to pull that bias test voltage down...I suspect
Learning at the expense of someone else...Priceless!

Helping someone like you did is one of the most satisfying things. 😊
Great video great learning for all of us
thank you:)

I'm thinking they must get a lot of returns and one wonders how they can make money with that happening

yeah, I agree Steve ... we pretty much have to go OEM for those
so pricey though!

Bias voltage on a 5V ref line? Never heard of that, but that doesn’t really mean anything 🤣 Cheers Denis 👍🍻

Take the old one apart. Maybe you'll find the problem and you'll have a spare.
we're not throwing it out, that's 4sure Dave
I think they can be cleaned and freed up...maybe
