CKF sensor question(honda related)
iam doing a B swap in my 97 civic rite now as we know thats obd2a , i put all my obd2a sensors and obda dizzy on the obd1 motor and am planning on running a obd1 ecu , here lies the problem obd2 engine run the sensor bolted to the oil pump, i dont have this sensor and my oil pump does not have the mounting holes. so can somone verify for me if this bit of info i came across is correct , it basically says as long as i run my car on a obd1 ecu i will not need this sensor . just looking for some input on what i should or need to do in this situation .iam not trying to buy a obd2 oil pump and that sensor (thats like 300 dollars) all input is greatly apreciated as its rare for me to have a question honda related haha
"If you're planning to use a US OBD2 ecu to power the OBD1 engine, you'll need a work around for the CKF sensor. This is the crank sensor that's integrated on the oil pump found on all US OBD2 engines. Only US OBD2 ecu's look for this sensor whereas OBD1 and JDM OBD2 ecu's do not...which means OBD1 & JDM OBD2 engines do not have a CKF sensor on the oil pump"

yes i have a obd1 ecu i got a P30(obd-1 B16 del sol ecu)
alrite so i dont have to run a obd1 dizzy also? so basically that sensor was non exsistant until 96 , i was always under the impression it was inside the distributor on the obd1 car and on obd2 they moved it to the oil pump i was told this very earlyer on in my honda addiction lol i guess i was mis informed , i always owned obd1 vehicles so this obd2 stuff is new to me haha

ok well that diagram just proved that obd1 dizzy's do not have CKF sensors built in , so that proves the first statement in my post that as long as i run a obd1 ecu i can do away with the CFK sensor . thank's alot everyone for your help , i got all the info i need now . thanks again .
The sensor by the oil pump is not what some people think of as "Crank Positioning Sensor". That sensor by the oil pump is ACTUALLY the "Crank Fluctuation Sensor". The "Crank Positioning Sensor" is integrated within the distributor in which all OBD generations have. The "Crank Fluctuation Sensor" is integrated on both OBD2 generation..... thus, OBD2 ECU's look for.........

Yep, don't need the CKF unless the ECU specifically needs it. You can't believe the amount of people who think the CKF is the crank position sensor..
