So I have a 99 EM1 that recently started displaying a check engine light. My first problem is decoding the CEL to fix the issue. I have a OBD1 p28 ECU. I have tried the paper clip trick but when I turned the car to the "On" position the CEL was not lit up and did not blink. I tried to reset the CEL by disconnecting the battery and also by pulling the 7.5 fuse from the fuse box.

So I cant check the code and I cant reset the light. Any help would be appreciated.

 

Ok so I have managed to get the code and it is throwing code 9 CYP - cylinder sensor. I have read that this means buying a new distributor because the censor can not be purchased by itself. Is this something I need to replace now? Will it cause harm to the engine? I just replaced the rotor, cap, and wires not too long ago.
