1989 2.9L... does an EGR valve exist?

[eightynine4x4]

Hey all,
Saw this vid of some basic 1st gen parts replacements....

And am confused about my 2nd gen truck now...
Does an 89-92 2.9L have an EGR valve?
Don't see one in the engine bay, yet. I do see where it would be mounted, but it's just closed off with a plate.
Also don't see an 89 EGR valve anywhere when searching for parts.
However, i DO see EGR valve gaskets.... eh?
And i see EGR sensors all over the place.

So what's the deal? Is there some adapted version of it elsewhere in engine that can't be cleaned/replaced? ... but still requires a sensor?
If so, what's the deal with the gasket existing? Simply to mount the plate that covers the former OEM location?

Or is it possible that a previous owner of my truck deleted it to gain performance? Really not seeing any for sale anywhere so not thinking it exists..

Only 86-87 2.9s had EGR.

88-92 do not.

88-92 also do not have a knock sensor.

Interesting! Any idea why they did without these features?

The EGR? No. Guessing they figured it wasnt needed.

Knock sensor i heard went away because it was detecting valvetrain tick as spark knock and retarding the timing...then people brought them in for warrenty wondering why their 2.9 is giving 2.3 levels of performance
