I have a p28 that's been throwing a code 14, trouble shooted it back to ecu.. how would I go about fixing it? More details the better.. please and thank you.

 

You're the one who needs to provide more details.

How did you trouble shoot it back to the ecu and why do you think it's bad?

 

Ugh hardwired iacv, it works, ran a jumper from iacv to ecu, No change, emptied 2 cans of carb cleaner searching for vacuum leak, No leak...I've read every forum there is for this issue. Bad ecu, if u don't have the info im asking for please don't clutter my thread.

 

Oh yeah and code 14 is a iacv system fault or bad ecu

 

Way to shoot yourself in the foot. No one is going to help you with an attitude like that when you were only asked to provide more info. I am def not going to give the advice I came in here to give!!!

Good luck figuring out your own problem.

 

Likewise. Good luck OP.

 

Excuse me, why should I explain my self all I want is a circuit diagram for the p28 focused on the code 14 error. Instead of going through and telling you voltages and what all I've already tried.

 

You hadnt asked for a circuit diagram till now...and wait, thats "all you needed"

wow

goodluck figureing it out on your own and adjusting your **** poor attitude

 

Here are a couple options for posters:

1) Give enough detail in the original post that people will be able to give useful help immediately.
2) Not give enough detail, but then politely provide it when it's asked for by someone trying to help.
3) Not give enough detail, and then sh*t all over the first person who tries to help.

Oh damn you already picked option 3. I guess you think we're either mind readers or servants that are here to help you no matter how we are treated. Well if that's the case you're wrong on both counts.

 

^ Perfect synopsis

 

Damn, sorry for being a *****, I was just outta surgery hopped up on the drip... And yet I still wanted to fix this haha but yeah I just need a circuit diagram foe the p28 focusing on the code 14 fault. Or whatever u have. I appreciate it and sorry again, blame the juice

 

Thank you.

As far as ecu, good luck!! I have been trying to find circuit diagrams of a p28 for a few months with no luck. I was hoping to fix my ecu but bought another p28 for $70. I would recommend just spend the $$ (50-100 bucks) and just get another one that works.

 

Yeah I figured.. may just break out the magnifying glass and multi meter and see if I can find something... Thanks for the heads up though

 

No worries.

I'm with speedjunkie -- probably a better use of your time getting a new ECU. I'm not sure where you could find I diagram of the ECU itself. I looked for a bit and couldn't find anything. Diagrams of the system outside the ECU are a different story but I'm sure you've already sorted through that.

 

Yeah, o well. Thanks anyways guys

 

Well I traced the circuitry from a9 to d10 and q21.. they look ok as far as not being burnt... What do u guys think?

 

Came back yesterday to see I got kicked in the nuts and just back paged.

I'll try one more time.

How did you come to the conclusion the ecu is bad? I'm not asking you to wright a book but details are important. Don't say this tested good and this test passed. Simple details.

What did you test and how with what results?

 

Did you even try a known good IACV?

 

if its the ECU, we can fix that code

I've got a skunk2 chipped p72 and a virgin p75 if you just want to buy a new ecu.

 

Throwing money at it and randomly replacing parts isn't the correct answer.

Maybe the OP's troubleshoot was legit, or maybe it wasn't.

If you break your shoe lace do you buy new shoes or get new shoe laces?

Not my money.

 

Because, when I put in the stock p2p No issues... P28... Issues, and I replaced iacv first

 

So I take it you don't care to give info on your trouble shoot methods...unless this is your method.

To trouble shoot electrical (your issue) you need a multi meter wheather it be digital or analog. You need to be able to test voltage, resistance and continuity.

My crystal ball is in the shop for repair so I guess I'm done here.

 

Dude I don't know what ur problem is but ur talking to someone competent enough to know the obvious, sorry ur butt hurt that I don't want to explain how everything else is OK and I know it's the ecu.

 

Yeah if replacing with a known-good fixes the problem, no need for troubleshooting. I guess your options are to send to Xenocron for repairs or replace the ECU. I doubt you're going to get the kind of information you're after unless you have a private conversation with somebody quite knowledgeable.
