Anyone else ever have this problem?? I tried retarding and advancing the timing at the distributor, still had the problem. The timing belt looks like it's on the mark. Anyone got some suggestions? It has 87 octane in it now, so hopefully higher octane will rid the pinging but then code 9 will still be evident.

 

That's more then likely your problem. The zc came in the jdm si it needs 92 ron or higher gas. So fill her up with pre.

 

I agree it must have 91. You can also have alot of carbon deposits in the head. I've never have had a pinging problem that bad and i've had two ZC's. Don't add any fuel additives it will only make it worst try a different ecu integ or JDM ZC there hard to come by but it makes a world of a difference i have one let me know if your intrested

 

sounds like it might need some 110 octane ethanol??

Just fix the problem. With the compression these motors have, 87 is just fine.

The problem was the timing being off. With a timing light it was plain to see that. Oh and another note:
Changing the timing belt is a 2 person job!!!!!!!!

 

How did u fix it? I'm having the same problem with my rebuilt d16a1.

 

You are right. I set my igntion timing light using a basic Inductive Ignition timing light and code is now gone. Thanks!

 

Well, after driving for about 40 more miles, the code 9 is back so its not ignition timing related. I am wondering if its really the distributor. Is your problem all solved after setting the ignition timing?

 

A while back my D16a1 was throwing a code 9 and under full throttle it would hesitate and misfire. I replaced my crank angle sensor and the problem went away

 

try replacing the cylinder position sensor (cps) on the end of the exhaust cam of your zc...that may fix it

 

which one is the crank angle sensor and where is it located, I am not familiar with sensors?

 

when u put this cyl position sensor back on to the end of the exhaust cam, does it matter how its put back on?

Also, i checked the ignition timing again today it needs to be moved to the red mark between the green marks but the distributor won't retard anymore to get to it? Why would this be?

 

crank angle sensor is in your distributor, so you'd replace the whole dizzy if thats your problem...

the cylinder position sensor only keys into the cam one way...so you really cant go wrong there...

as far as the timing, i dunno

 

Nope. Replacing distributor did not resolve the problem. Drove it around and code 9 came right back. Check Engine light came on as soon as it missed. So here's some usefull info for D16A1 with code 9:

The Cylinder position/Camshaft position sensor is located at the end of exhaust camshaft, next to the distributor. Code 9 on these motors reffers to this and not the distributor. So before you replace the distributor check this sensor. All electrical connections to it, normally its the connection and not the sensor itself. In my case the connector had some fluid in it and was shorting out. While the car was idling, I was checking the CYL sensor connector (green) to make sure it was plugged in all the way. I twisted the connector, engine missed, check engine light came on. So turned the car off, cleaned the wires and the connector, took the negative off the battery to reset the ECU, started the car, no code 9. Drove the car for about 65 miles, no code 9, new distributor does make it run very smooth though.

I'm sure other people got rid of this by replacing the distributor but after much research and troubleshooting, for me it ended up being the cyl sensor.

D16A1 Code 9:
1. Check Ignition Timing
2. Check CYL sensor and related wires/connectors- located at the end of exhaust cam, next to distributor

Thanks to my new best friend 'LUCKY' at Honda delaership, he got me this info.
I'll drive it around more for a few days and post a confirmation.
