Default Need help

Ok the other day I was coming home and my check engine light came on. Well as I had to stop and start going again I noticed between 2-3k it had a miss. Checked the ecu when I got home and it was a code 9. Well this kept getting worse and worse. I asked and everyone said it was probable my dizzy. So I replaced my dizzy and also put on a MSD external coil while I was at it. I pulled my ECU fuse, waited about 2 min put it back in and cranked it and it still flashes a code nine. I havn't drove it yet. I will in a few min after I am giving it time to reset the ecu. Why is it still flashing code nine?

You might not of left the fuse out long enough, take the battery cables off the battery and let it sit for 10 minutes. Rub the 2 cables together, this will get all of the electricity out of the system. If they won't work, you might have a wiring problem. A little more

Code 9 - No. 1 Cylinder Position Sensor

It's the third sensor in the dist., and it detects the position of the No. 1 Cylinder, as the base for the Sequential Injection. It can also be located on the camshaft of DOHC engines.

CYP sensor is mounted on the exhaust cam on the ZC.

If the dist. base bearing starts failing, it will heat the sensor(s) up, destroying the magnetism thus causing a code(s). It will lose 10% of it's strenght, each time it is heated up to 170 degrees plus.

In most cases, replacing the distributor is the only alternative. Especially if the bearing has failed.
Honda does don't stock the bearing by itself, but other after-market compaines are said to have one.

If you have problems starting the engine, or drivability after the install check your cam aligment. The seizing bearing might have caused it to jump a tooth/notch or two. From the extra drag due to the bearing failing.

Yeah, a cut in the wire going to the sensor or to the ecu.
