I re tested the new dizzy pin out for resistance all is good
how do i trouble shoot from the dizzy connector to the ecu?

How do I test the cyp wires for short?

HFXCIVIC

still trouble shooting this cel 9 code so i have been trying to test all the wiring between the dizzy and ecu.

So i found the pins in the ecu connector for the dizzy , they are showing a resistance of 350 ohms. I don't have a continuity tester on multi meter.

i tried to test the connector the dizzy plugs into but i couldn't get a reading off of it


any suggestions on what to do ?

Former User

Measure the resistance between each CYP wire and body ground.

HFXCIVIC

Thank Ron, im not really sure to do this can you please explain a bit more thanks again

Former User

Key off -- Unplug the ECU connector that has the two CYP terminals. Set multimeter to read resistance on the lowest scale (e.g., 20 or 200 Ohms), if it does not auto range. Touch one meter probe to one CYP terminal in the ECU connector and the other to the metal frame under the dash.

Thank you soo much . Should i discnnect the neg battery terminal ?

and how much resistance am i looking for?

I just tested it and it gave a reading of 1 which I'm pretty sure mean there's no circuit and it's grounded???

Former User

Not necessary but it wouldn't hurt either.

Infinite/Too high to measure

1 Ohm?

HFXCIVIC

1 meaning infinite /to high to messure...
So I'm pretty sure this means everything is grounded?
ay suggestions on what to do now?

Former User

Both CYP pins?

No, it means the wires are fine.

If both CYP wires are fine, then swap in a known good ECU.

HFXCIVIC

Thanks ron

both pins are showing as being infinite/to high to measure.


When it come to ecu's i'm in canada and if i buy a ecu off ebay from the states will it work in my Canadian car?

Former User

U.S. and Canada ECUs should be the same, but if you can borrow one for testing purposes, do that rather than buy. What car/engine?

You also might want to check whether the code is still thrown after unplugging and replugging the ECU and distributor connectors, just in case there was just a bad connection.

HFXCIVIC

so its a 00 civic dx d16y7 p2e ecu ....

i i really don't know where i would find one for testing purposes

everything is hooked back up and i guess we will see if it throws the code again now


Ron you have been a huge help with all this thanks so much !!

My ignition coil and igniter went out today, no good.
