Ok so i got a code 9 and i went out and bought a new dizzy. Codes still there, so i did all the tests for the wires and all read within specs, so i checked all the timing and its all dead on. So my question is what else could cause it to throw a code 9? Cause im completely lost on this one. Thanks in advance guys.

^You could do that or you could save some time and just pull the clock/radio fuse in the under hood fuse box for 10 seconds to reset the ecu.

If you reset it already and the code is still there, I'd try switching out your ecu for a known good one to see if the code comes back.

Hmmnn .. when u swapped out the dizzy did u do the whole thing like the rotating am and bracket or just the cap? Cuz that sensor ur looking at code 9 is that metal 6 shaped hing behind everything when I got that code it tuned out that it came loose

Alright i had the same problem. i replaced the dizzy, the whole thing, and still got the code. I swapped my P12(F22A1) ecu, with a chipped p28 ecu and BAM, code was gone.

^^fail lol all u gotta do is disconnect the 10 fuse under the Hood to reset the computer lol

Why don't you guys quote each other? so no one get confused to who your talking to. Just makes things a little easier.

Yea cleared the code. Still keeps coming back. Ok. Well there's no other prludes around where im from and a new ecu costs $800 from the local dealer. Any other ecu's from lie a accord with a f22 will work? And if the ecu was bad would the car still run?
yup! the p12 was a little more aggressively tuned then the accords.....i think.....maybe its the other way around. but they will work.

I bought a whole brand new dizzy from the dealer. I got a bad negative battery cable that's barley on there but the car still runs fine beside that one sensor being bad. Think that could cause it?
nope, i doubt it. if you have a volt meter or what ever they are called, you could check and see if its good or bad.

Ok. Ill see what i an do for getting a chipped on my buget is kinda tight right now.lol thanks man + rep for ya.

I had that same issue when my car wasnt cranking the code would throw because the engine wasnt turning it wasnt getting a signal from the sensor. Is your engine turning over?

Thanks, i know i think it was cause by bad weather stripping on the windsheild cause its peeled up in the coners, cause the ecu had water damage to it. but now iv ran into another snag...

Shes bogs a bit on take off not much low end tourq it feels like. i think this could be cause from the header gasket being blown out so its got a leak from the header witch would explain the no low end tourq cause theres not shit for back pressure.
