where the hell is it...?! i'm trying to wire up this b18c with a 2000 si wiring harness and the only plug i have left is, according to my haynes repair manual, the crankshaft fluctuation sensor (ckf).... also according to my repair manual the ckf is located next to the crankshaft pulley.... does that mean behind the timing belt cover? i already changed the timing belt and closed up the covers and pulley but i don't remember even seeing an electrical connector back there.... so where is it? or do i not have one? any help is appreciated. thanks in advance.

 

Is the motor OBD1 or OBD2?

It only exists on the OBD2 motors on the B18C1. I believe it monitors the crank speed for misfires.

 

OBD2 J-spec B18C (ITR) does NOT have a crank flux sensor. It also only has one O2 sensor. You also have to use a J-spec ECU if you are using the J-spec VTEC solenoid, or you have to use a USDM VTEC solenoid if you are using a USDM ECU.
