so about 2 weeks ago i had this code and it was pissing me off bc it was causing me to bog and felt weak through out the powerband. i ended up fixing it with a new crank sensor and re-soddering of a part in the ecu that melted bc of the code...

today i was driving ''normal'' and it bogged out of 1st and the check engine light came on, pulled over and sure enough, it was that pesky code 9 back to haunt me.., car feels a little weak again...

my question, could it have been a coincidence of a bad crank sensor i put in, or maybe my wiring is all fd up causing it to over load.. i know my speedo wiring is out of whack bc it reads 20-25 mph ahead but when i come to a complete stop it goes down to 0. any ideas of what could be causing this damn code from reappearing? ugh, i dont feel like having to fix this every 2 weeks.

B20VTEC, compression 13.3-1, tuned on hondata s-300 p28.

i was told that s-300 are prone to this damn code 9 problem, that the part (not sure what i wasnt paying much attention when they told me first time they fixed it bc i was just excited that my car was going to be running to its fullest finally) over heats and melts and causes the code, not the sensor itself...weak!

 

forgot to mention, 1000cc injectors hooked up to a resistor box, and everything is flowing through a butchered 95civic ex harness... im thinking im having an elictical problem bc of this, so im thinking of just getting a new harness all around and wired everything perfect or as perfect as i can... would anyone chime in?

 

s300 is by no means to blame for your code 9 issues.

The cyp sensor is located inside of the distributor.
If you install a distributor from a vehicle which is not throwing a code 9 onto your vehicle & your vehicle is still throwing a code 9, it is likely there is an issue with your wiring or ecu it's self. The s300 module it's self will not produce cyp sensor issues.

 

I see. Hmm I'm starting to think it's electrical burning spmething out...
