So I bought a project car a while back.
It is a 99 civic si with a swapped B16A1.

With my obd2 ecu it would throw a crankshaft position sensor code and this engine doesn't have one. Just get a new ecu and it should fix it. Simple enough, right?

Well I bought an obd1 ecu that said it should fix this code.
However, the scanners won't read this ecu now and I still get a check engine light. I don't really know what to do. I just want to get this car registered.

What scanners? How did you install the OBD1 ECU?

HuntsAlone

I just went to two shops, a sears auto center, and an oreilly's. One was an automatic scanner and the other you input it yourself and both didn't work. I used an ecu jumper conversion harness from obd2b to obd1.
EDIT: I was looking at some connectors near my ecu because I was doing some research. I saw the check connector wires next to my ecu and it only had one pin in there and there wasn't another one.

Is there anyway I can get this car to pass obdII smog?

What state do you live in? What are the engine swap laws there?

HuntsAlone

I live in Oregon. I don't honestly know what the engine swap laws are here because I bought this vehicle when I was in the military still and was stationed somewhere else.

Former User

If Oregon requires your ECU to communicate with a scanner, the OBD1 ECU won't pass.

Did your test sheet state reasons for the failure? Post the sheet.

HuntsAlone

It passed the smog emissions you just can't have error codes.
I got code p1337.

Former User

The code is for the Crankshaft Speed Fluctuation (CKF) sensor not CKP. Do a search for CKF trick.

HuntsAlone

the CKF trick won't work because I am missing the wires where the pin should be to do the trick

Former User

Why not install the wires?

HuntsAlone

I don't know where to begin. I'm honestly kind of a nooby but I'm trying my best to learn. What do I need, sir?

Former User

So what wire(s) do you think you're missing?

HuntsAlone

C1, C4
C11, C14. I'll attach pictures so you can confirm this or not.

EDIT: I think I am the stupidest man alive. I thought my vehicle was obd2a when it was obd2b when I bought an obd1 ecu I even bought the wrong conversion harness the first time. How did I not think of this before? OH MY GOODNESS. I am a dumb dumb.

HuntsAlone

IN CONCLUSION: You helped me realize something that I could have done all along and I am able to fix my car. You sir are a genius and I wish I could give you something. For now a hug will have to do
