ok i have a dumb but serious question ok on the b18 motors the crankshaft speed fluctuation sensor is a 2 wire plug and on the 96-98 civic d16y8 motor it is a 3 wire plug. the wires are light blue, white, and a black wire. the blue and white wires plug into the sensor itself but the black wire spirals around the other 2 completely stripped and plugs into nothing. so on the b18 can i just cut the 2 wire plug off the sensor and splice the 3 wire plug in to the sensor and just let the black wire chill unpluged?? or does it absolutly NEED to have that black wire SPIRAL around the blue and white ones??? any suggestions would be AWSOME. thanks alot.

 

Which b18 do you have? obdI or obdII?

If it's a obdII jdm motor, then you might want to perform the ckf trick to use the obdii usdm ecu so it idles correctly. Located HERE!!!

Other than that, we need to know information such as the model car and motor as well as ecu being used.

 

its a ls/vtec: 96 b18b1 block (obd2a) and a 99 b18c1 head (obd2a) the car is a 96 civic ex (obd2a) the stock p2p ecu will be used for only the breakin of the motor. then when i boost it im going to chipped p28.

 

Anyone know where the crankshaft speed fluctuation sensor is located on a 97 EX d16y8 motor? Have to swap it out reference CEL code. Thanks!

 

It's next to the crankshaft sprocket that drives the timing belt. The crank pulley (that drives the alternator, A/C, etc.) and timing belt cover need to be removed for access. It's common to damage the sensor wires during a timing belt job and/or letting them get into the pulley. You may be able to splice them.
