What would cause a code 9 on 1989 Acura legend coupe if the sensor is good?

Answer 1

Code 9 means: CYP Sensor Position 1

On a 1988 Acura Legend, this is:

True. But first check the ohm/resistance reading with a multimeter. It should read between 500 and 1000 ohms. You can check it on the terminals coming off the wiring from the passenger side, front of car , about 8 inches below top of engine, just to the right of the plastic timing cover (behind it, towards the engine). There are four terminals coming from the sensors (2 sensors inside the timing cover, below the timing gear). One is the number one cylinder sensor (CYP, Number One Cylinder Position Sensor) and the other is the Crank Sensor, to sense the speed of the engine, to time the spark and gas input. The other sensor on my car, the TDC Sensor, (INSIDE THE DISTRIBUTOR, BELOW THE ROTOR AND TOP PLATE) only senses when the engine is at top dead center, not which cylinder is at TDC. My engine shuts down after starting, because this sensor is ok, but the info is handed off to the ECU, which then relies on the other two sensors to keep running.......Crank and Cyl sensors, under the timing gear. All 3 of mine test ok. But since I disassembled the rebuilt distributor from the auto parts store to make sure it was not bad, I reassembled incorrectly, I think. There is a gear inside which distributes spark and that has to lined up. Now I need to figure how to check my installatioin of this gear.

Anyone out there can help?
