I just found instructions on "crankshaft fluctuation sensor" {service and repair} under my seat after clowns replaced my distributor that did not solve my problem. Is this CKF sensor in any way related to my distributor? Or could it be related to hard start stalling.
1999 Honda Civic 120,000 miles.

Thanks

If you have a new Ignition Control Module, coil, remanufactured distributor housing, distributor cap, rotor, spark plugs (NGK), and spark plugs wires, your Civic's ignition system should be in pretty good shape. Provided all of the above is true, your car should run like a "top," provided they set the timimg correctly and replaced the fuel filter. Positively verify that a NEW fuel filter was installed--this simple oversight could be what's causing your car to stall. The fuel filter should be replaced every 60,000 miles or 4 years, whichever comes first.

The CKP Sensor should only be an issue, if the remanufactured distributor has a problem. These sensors are not serviceable; therefore, if there's a problem with any internal sensor, which should throw a code, the only thing that can be done is to replace the distributor. As I mentioned before, non-Honda distributors have been problematic on this site. From afar, it's hard to tell what's the real problem. Try to find someone who can verify that no codes are being thrown and who can check the engine timing. I'm inclined to give the remanufactured distributor the benefit of the doubt, at this point.

Isn't the CKF as he is calling it on the crankshaft in the timing belt area. I have only seen a picture of it once last week, that time there was a code and a wire was broken during the timing belt job by the owner. I do not think he is referring to the CKP in the dizzy.

It will need to be hooked up to a scope during a no start scenario to prove if it is bad or not. I believe it is also a magnetic pick up type sensor, one on each side of the crankshaft.
