Hello i have a 92 eg hatch with a ls turbo swap in it. i recently got it finshed and i had a check engine for code 9 the cyp sensor. So i did some research and ohmed out all the plugs on the distributor and they all checked out at 380ohms. So then i tried a diffrent dizzy for fun still check engine tried 2 others and still a check engine. Then i also tried 3 other good chipped ecu's and still nothing. Also replaced the wireing from the ecu to distributor and still had a check engine..... So i am runing out of ideas to try if anyone had any other thoughts that would be apprecheated thanks.

 

Did you try a different jumper harness?

 

What do u mean by jumper harness?? its all obd1

 

adjust your valves
90-91
intake - 0.006 to 0.007 inch
exhaust - 0.007 to 0.008 in

92-93
non-vtec intake 0.003 to 0.005 in
non-vtec exhaust 0.006 to 0.008 in

and make sure your timing is dead nuts on time.

 

Ok......n but what does adjusting your valves do for a code 9?

 

Are you using an aftermarket distributor? I have seen many aftermarket distributors throw this code for no real explainable reason. I have also seen where the sensors ohm-ed out correctly but gave a weak signal (seen through an oscilloscope). If you were to find a way to move the pickup closer (read thousands of an inch) that would increase the signal strength and might solve your problem but I would try an known good OEM dizzy first and if that doesn't work I would check your wiring again and also make sure its shielded. Hope this helps.

 

if your timing was off,it would effect when your distributor is firing.

 

Adjusting valves does NOT affect mechanical timing and likewise electrical timing.

 

Thanks for the responces guys i tried useing 3 other good dizzys i got a 4 day weekend so i will try goin over other things and mechanical timing is right i checked that many times. But open to any other ideas u guys may have.
