I had a b16a from japan in my 96 ex and pulled it out to swap blocks with a b18c1 with type-r pistons, during this build i noticed a couple differences but the most disturbing was the fact that the b16 had a sensor next to the bottom gear for the T-belt thats behind the crank pulley. The problem part is how theres no place to mount said sensor on the b18 block and i dont know if i need it, im guessing if its there and was plugged in, that it was there for a reason anyone know anything here that may help shed some light?

 

obd2 requires teh CKF, Crank Fluctuation sensor. It will be found on almost all 96 up B and D series blocks. It sits on the oil pump, which is slightly diff from obd2 to 1 to account for the mounting of the sensor as well as sprocket with the pickup.

 

so, is my solution to get a different ecu? and leave that sensor out, (its obvious i have to leave it out, there's no where for it to go)

 

Yea my friend has a gsr motor in his 2000 si....same problem as u....he throws a code for cfk since he is running the si computer.....your car will run fine but will throw a CEL......any solutions on how to solve this????

 

to solve it the way i know to do it is put the ob2 oil pump and lower timing sprocket on and then install teh sensor.
