As I counted my chickens a little too early in my last post/update and the dash light came on literally the following day from the post, I had to do a little more investigating, into the KS sensor issue.

This time I decided to remove the pin from the ECU connector to check the wiring to the actual pin. A little fiddly to do, especially if your eyes are over half a century old but with various magnifying lenses I managed to remove the D4 pin from the plastic connector block using some jewellery screwdrivers. (The internet providing some useful info on removing pins from a Honda OBD 1 connector). I was expecting/hoping for a poor wiring joint, or even a small piece of dust but no, it was attached as it should be. There appeared to be nothing wrong with the pin at all.

So the only thing I could conclude, after examining the pin, was either the small tension tabs perhaps being a little slack on the internal side of the pin, or they are broken and should attached at both of their ends, thus causing a poor electrical connection to the pins on the ECU. So very delicately I bent the tab slightly, so it would have more tension to the ECU PIN and snapped it back into the plastic connector housing.

So this time, a week and half has passed and the warning light has not returned, so I actually do now believe I've solved the issue. Hopefully this bit of info may help others before they perhaps spend many hours and possibly money on trying to solve a re-occuring annoying electrical problem.
