I've been told by multiple sources that the trouble code my ecu in my evo does or does not exist, so i was wondering if someone could provide a list of the diagnostic codes for the 03 evolution or if they could post a link to the thread or web page that would have that? Thnx.

 

What code are you getting? You may be able to just plug the code into a search and see what it brings up!

 

p305

 

First off a google search (p0305 code) yields many results. Interestingly enough the results say it is a misfire in cylinder number 5. Not quite sure what to make of that. I also forgot to mention that there is a standard for the OBD-II codes. I don't believe there are any special codes for the Evo as far as OBD-II is concerned.

Check the link for a list of codes:

if i'm not mistaken the evo should only have codes p301-304 since it is for cylinder misfire. if it is a p305 that means cylinder 5 misfire...damn you got a 5 cylinder evo? code must be wrong. have the code repulled.

edit looks like i was beat.

 

I'm sure you've already seen this, but I hope you get everything figured out!https://www.evolutionm.net/forums/sh...ad.php?t=69304

 

thank you. I was looking for this thread. Never seen it before, but my friend told me about it.

 

by the way, has anyone ever heard of an "overboost" code? if so, what is that, and what causes it if you are running stock boost?

 

Sorry dude, I'm no help on that one....

Here's a bump for you though!
