did a recent motor swap from my 89 hatch to my 91 hatch everything runs good but i keep getting a persistant code 9 for cps i keep clearing the code with the ecu/hazard fuse and it comes back everytime as i drive down the road the car died and i had intermittant spark . checked the specs for all the sensor inside and it all is good. so perhaps it was the igniter. in the mean time im waiting for my new dizzy to come in the mail . the wires for cyp had appearded to have been switched back and fourth with butt conectors 3 different times so perhaps i should rewire with some shielded wire from ecu to new dizzing if the new distributor doesnt solve the problem

 

Check and make sure all your wires to your dizzy are good know alot of guys that changed it and it was just wires.

 

like the wires are old and have to much resistance that so the computer cant read the signal from the dizzy perhaps?

 

i got a new dizzy. and rewired it runs like **** . it bogs and hardly has throttle response . its timed right new dizzy ,rewired, different ecu ...wtf... im not sure if i got my code to go away yet either but its runs like a harley davidson and has no throthle response in just boggs help please

 

come on guys please help im running out of ideas and i cant afford to do obd1 swap right now

 

is this car converted from dpfi to mpfi if so check your wiring underneath the dash i had the same problem turned out i had two wires missplaced.. i can seem to remeber though if it was the injectors or distributor..

 

Yes ive checked all the wires on pinout diagrams yes it also has a vtec sub harness wired in but no vtec its stock ls.. It runs like out of time but the timing is good . No matter where I position the dizzy the car wont running. It trys to start but cigar . Im taking.it to tuner shop.n get them.to.look.at it

 

you more than likely have the cps wires mixed up backwards. Have your tried switching them around?

 

currently getting this problem with my dpfi-mpfi, obd0-obd1 z6 swapped ef, not the dizzy not the ecu,and not the cyp wires....

tested my dizzy on another car and no problem, theirs still throws the code on mine.
swapped another p28, still shows cel
bypassed the 2 cyp wires directly from dizzy clip to harness with 2 wired outside the car, even switched them around... still cel 9

looks like we have the same problem

 

Are 100% sure your in time. You can be one tooth of and it'll be running fine

 

would that trip the 9 code?

 

it was my wire harness . it was ffd up so i swapped it with one of my old ones and wala magic the code never cam back. even after i rewired with shielded wire it never fixed it till i swapped the harness.

 

my friend logan has the same swap in his crx and he had the same problem but it was becasues he was running b1 cams with a obd0 dizzy,
