2000 Civic SE 1.6

My CEL is on and giving me the CYP Sensor code and the code for the Crankshaft Fluctuation Sensor (which I already changed once about a year ago). The car drives OK but is definitely missing some power, taking longer to get to higher speeds, etc.

It says in the book I need to change the whole distributor if the CYP is bad... this sounds expensive and like there may be another way?

There should be a diagnosis flow chart in the book, if you follow it, it will tell you how to test it. And yes if the CYP sensor is bad you have to replace the whole distributor.
