Crank sensor error

[Tykota]

I am getting a crank sensor code, I've confirmed I was getting signal but I am not having success with new sensors either.

Current set up:
96 civic hatch
Kpro on a PND-A55 ecu
TSX ckp sensor
K24a2 with accord 5 speed manual transmission

I'm wondering if anyone has ever ran into this and if so what their solution was. I have swapped my harness to use the tsx sensor to no avail. Wondering if I maybe need a different sensor or something.

Car runs and drives but naturally I can't rev out because of the sensor code and I've been fighting it for 6 months.

Preemptive thank you for any help.

Just to think out loud, please let me know if this thought is correct.

Since I have an automatic rsx ecu, and I have a tsx engine I might have to use an rsx sensor? Or will I have to switch the pins to be the rsx pinout again? Or will I need a different cars sensor?

You should use the K20 sensor and see if that resolves the issue.

Thank you sir! I will keep this thread updated and see. I'm using a k24 crank hence why I used a k24 sensor but I will give a k20 sensor a shot. Should I wire it using the rsx wiring pattern or just wire it using the k24 one I have soldiered in now? I figured if you aren't sure I'd just use the one I have now then switch it if it doesn't work.

Gonna have to order one so it might be a week or so. I am guessing since the pinout is different then changing to the rsx pinout will be what I want.

I guess I should mention,

I kept trying to depin on another harness that I had to no success so I wound up soldiering the wires in the harness vs repinning into a spare connector. Would that cause issues? I tested for 12, ground, and signal where the diagrams states they should be for k24s several times and it was there every time.

You need to use the K20 sensor and the harness must be wired for that sensor (02-04 RSX).

So I bought a sensor, put it in. It worked. Revved all the way up, drove the car and had some other issue. Went to fix the other issue and all of the sudden I no longer can rev our. I've hit an issue again with the crank sensor code. Not sure what to do at this point, I've got 12v ground and signal from where they are supposed to be.

Just to express the troubleshooting I've done.

I have the following:
No continuity with the vehicle off between any of the 3 wires
Continuty to the ecu for the signal wire
If you're looking into the vehicle I have a low voltage only when the car is on for the top wire
Ground middle wire
12v with key on for the bottom wire.

Just tested the voltage my ecu is getting from the crankshaft sensor. Looks like 4v. Is that normal or am I getting an incorrect reading? From what I read it should vary between 1-5v but I didn't see any variance.

Sorry for so many repeat posts. I'm actively diagnosing as I write this. Turns out with voltage tested at ECU with key in it was 5v and then 4v after starting.

If it does not have continuity to the ECU on the wires then that could be the issue.
