any one got any ideas ? got an 96 acura integra with a j-spec block in it jus put it all 2gether and have a check engine light on and the scanner reads out crank sensor b fault no signal . and cuz that light is on the car wont crack vtech . supposedly im hearing that the j spec block does not have crank sensor and the u.s. spec block does , also im hearing that the dizzy has both crank and cam positioning sensors in it and that i need to replace it . im kinda lost and wonderin if any body else has had this problem and or has a fix for this problem. oh yah also tryed a j spec computer and had same issue . please help

 

If you're talking about the crank fluctuation sensor, the JDM engines don't have it. That's not the same thing as the crank position sensor. We have no idea what engine you have though, so it's tough to make assumptions about what your engine would or wouldn't have.

The crank and cam position sensors are in the distributor.

If you've tried a JDM ECU and you're getting the same problem, I would assume that you probably have a wiring issue (no connection between the ECU and sensor) or a distributor problem (bad sensor).

 

Google "crank fluctuation sensor bypass" for the answer to your other question.
