I have asked this before in the integra Forum, but it is really urgent so I think I would get some more response to it here.

I got a GS-R with a b16a3 in it, and my check engine light is on because of a code 54 the ECU is throwing.

Bad or Missing CKF Sensor (Crankshaft Fluctuation Sensor)

Well the problem is, my mechanic said there was no sensor, there was no place to put it on the b16a3, no hole for it, no wire for it from the engine. Is it true that the b16a3 has no CKF-Sensor?
