You don’t happen to have three clearer pictures of those wiring schematics? I can’t really make them out.

they’re here in the search engine. You just need the right words.

Yeah I started playing around with that in Google.

So I have 12 V going to the sensor and the ground is good between the connector and the chassis and the connector and the engine.

I wanted to check continuity with the ECM wire but I didn’t get a chance to unplug the connector from it. . Not sure which of the two ECM plugs would have the dark green wire going to the speed sensor?

also I can’t find any diagrams that show exactly how the speed sensor male end plugs into the transmission. When I removed the sensor itself I saw that white plastic threaded male end sticking out with a square fitting in the middle which is obviously the drive to turn the speed sensor rod. But I’d like to know if I can take that male end out of the transmission casing and inspect it..

At this point a picture of what you are describing would be great as far as the sensor plug goes….

I see now. I’m going to pull out the assembly and check the gear

[Eg.h2o]

If the gear looks good, see if you can spin in with you finger. If it rotates, the press fit is loose. I don’t believe it can be repaired without disassembly of the tranny.

Well even though the check engine light is on,,, because this is a five speed manual if I leave it I alone don’t think it will have any negative impact on the performance/drivability of the car

[Eg.h2o]

I believe you are right so long as your state does not plug your car in for a state inspection
as it would fail.

Michigan used to do that but that’s all a scam it’s just a government money grab
