Okay so I am fairly sure my tps isn't good. But that is not my main problem.
When I went out to test it I found that the plug going into it was broken. The one that is part of the wire harness.
The top part looking from above is fine but the bottom part is broken off. It holds onto the tps fine, but it doesn't sit tight. you can wiggle it easy it won't come off but it moves around.
I don't want to throw on a new tps and have this jiggle around and blow it out, so I am trying to figure out what some of you who have had this problem did about it?
My idea is to just cut it off and wire on a new one. (don't have one though.)
Maybe some tape to hold it on?(heat seems to kill electrical tape so I am unsure what kind would work.)
Anyhow just throwing this out there too see if any of you have some obvious fix I am not thinking of.
I can get a pic and video if you all need one. This is on a 1989 2wd dlx, with a 22re.

I bet those connectors are the same across a bunch of models, you could try scrapping one from a junk yard and resplice the new connector to your wiring harness. Just make sure to take note of which wires are in which order by testing continuity from each wire to each pin on the connector.

Bonus points for some heat shrink wrap around the splice job to keep it nice and protected

EDIT: or you could use a paperclip bent around like a rectangle it to give it extra snap support. And dielectric grease on the connectors will ensure a good connection even if it jiggles

I will give the dielectric grease a shot for now. I was thinking a setup with some zip ties to keep it in place. Looks like I will be replacing a plug end this weekend. ... ? lol

I agree with jenny... find a junkyard, maybe do some research first and find yourself a TPS plug pigtail, then splice it in properly with solder and shrinkwrap.

Is that the proper application for dialectic grease?

Teuf

Googled this.
(It is not recommended to be applied to the actual electrical conductive contacts of the connector because it could interfere with the electrical signals passing through the connector in cases where the contact pressure is very low. Products designed as electronic connector lubricants, on the other hand, should be applied at the connection pins. )

jennygirl

Interesting. The dielectric grease seems like an electronic lubricant to me.

I suppose if you put too much it might short two contact points that are right next to each other in a connector.. Then I could see the point against. But the directions of dielectric grease say to use a very small thin amount.

A little pin sized dab on the tips of the male side contacts (how I always apply it) is not going to hurt anything. Filling the female side connector with a flipping gob of it and I see your point!

So this is how my tps is testing out.
Any clockwise movement from here produces infinite open. (0.85 feeler gauge in place)
It did a couple of times climb to 2.3K but it is just bouncing around. (its an auto selecting tester so it isn't even getting into the 20K range, most of the time.)
Last night when I couldn't get a good read I was thinking it was my tester but nope same deal today with good contact and a good tester.
