For starts I have a 89 Civic Si canadian and I checked the ECU the Distributer but it looks fine. Is there anywhere else to look for this type of problem. And also i bought a extra Distri. and ECU PM6 and Nothing. Also sometimes when i drive and pass 2,000 RPM it hesitates. And will this problem damage the Engine
Please Help Me With This Problem

Thanks Alot

 

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.

 

Will this harm my engine?

 

it almost sounds like your motor jumped a tooth on the timing belt
