I have 2 months fighting with a ECU error #9 in a P72 B18C1 with Hondata. I know that the error #9 is the No. 1 Cylinder Position (CYP).

I make all the manual troubleshuting, cut the hondata jumper (return to OEM), n-check the ground wires, change the distributor with other car, change the ECU, etc, etc, etc and the code remain. I lost my time and mind with this problem...

The car have good iddle, start good, I dont have clue with this.

PLEASE HELP, ALL IDEAS ARE WELCOME


Thanks in advance,

Dariusz

 

it sounds like the obvious, (cyp) sensor

 

As you can read in my post, the ECU and the Distributor is changed (the CYP sensor is inside the Distributor).

 

Copied to Engine Tech were some awesome gear heads may be able to help! :thumbup:

 

are you able to verify continuity and solid connection on that part of your engine harness? no idea which wires since its a gsr motor...i do H...but the helms should have wire colors.

maybe some more history on the car and what was done to it.

Only time i've ever had that code consistantly was when my cams were misaligned. Have you done any work on the engine that requires timing belt removal lately?
