Default Diagnosing CEL 9 CYP? FIXED!

OK, I changed my D16Y7 engine out in my 96 civic. I changed the intake manifold to a Y8 mani, installed a timing belt and tensioner, new stage II clutch AND made a turbo kit for it. It fired right up. I drove it around the block and got a #9 CEL. So, the crank sensor is plugged in. How should I go about diagnosing this so I dont pull the timing covers and find out the issue is the conversion harness? Can I ohm it out or something along those lines or should I just pull the motor apart and use another snesor?

Thanks
David

Well I had Frank check Alldata and he says all the sensors for the 96 are in the distro. I will change the distro and try that after the rain stops.

I have a few spair OBDIIa distros. I will swap it out when the rain stops. I thought the cyp would be the sensor at the crank but the Alldata says its in the distro too.

Replaced distro with a known good one. Code 9 came back.......So does anyone know for sure on the OBDII that the sensor that would give a 9 on a conversion to OBDI is the crank sensor?

Yes but I was told after converting to OBDI that isnt used anymore and its just the distro that is in control. CoreyR just told me he once had a bad ecu and it threw 9. He changed it and it was fine. Im getting frustrated.

I just checked the pin out for the conversion harness and its definately correct. I guess I will get another ecu or borrow one to test with.

Its one of those boards that sticks up horizontal in the ECU if it is the ECU that is the problem...if you have any bunk ECUs around, try desoldering those boards (one at a time) and see if that works...
