YEA pointless, but Im wondering why I get vtec code #22 when I get on the highway and push the car over 85-100 MPH ?

D15B vtec. 95 civic ex coupe w/ stock p28 Virgin unchipped


I think my ECU may be retarted cuz I can wrap the rpms out to 9000 rpms and there is no rev limiter. ( i know, not safe, but I did this on accident and noticed NO rev limiter at all.)

I swapped out both sylenoids. still get the code, I wired VTEC directly to the ECU, nothing. May be the ECU being retarted and not having a limiter?


Ill get on the highway, hit 85-100mph, I don't rememeber what RPM's, but get CEL turn key offf then on and goes away, hit 85-100 MPH again it goes right back on.
Now see, when I first bought the car, took it on the highway and at high MPH like 85 MPH it threw a code, I reset the ECU. And Didnt have any codes showing up at all. I was concerned and well checked for codes anyway even though I wasnt throwing a code. I got I think it was #22? I think it was the vtec pressure sensor. So I swappd out both sensors, and wired vtec directly to the ECU with my own wiring.

I juts took a light trip on the highway and it seems I only get the code when I get on the highway. If I take off at a stop light in town, ill wrap rpms to 7000- 7500 each gear no problems, no codes. So I dunno. I "was" using 5w-30 fully synthetic casrol sytec oil, but the next oil change I dropped down to Vavoline 10w-30 semi-synthetic. and next oil change im dropping to regular 10w-30 oil.

** update**

ok one person said its a "soft" code.

What does that mean?

Yes, the code ONLY comes on or the CEL only lights up when driving it, but wont show up after.
Although, even though there is no CEL on, if I check for codes ill get the Vtec Code.

So what is a soft code and how do I fix it?
Is this something I shoudl be worried about?
Im afraid something isnt working that should be.

Code #22

floating valves huh, HAHA. you would have only done that once, i think you are referring to the rev limiter.

oh, and the code that is set would be very helpful. is it the spool solenoid???

^ lol

Metal Head

code set to what? Its a virgin ecu P28 stock civic ex ecu.

I swapped out both sylenoids. still get the code, I wired VTEC directly to the ECU, nothing. May be the ECU being retarted and not having a limiter?

I can't even tell if VTAK even engauges when it should.

I highly reccomend not to rev the d-series to 8300 your only asking for trouble. Are you 100% sure the ecu's not chipped? No kind of MSD **** on the car?

Metal Head

Positive, no chip no msd box nothing.

What is the stock p28 rev limiter suppos to be set at?

I'm not 100% sure.. I know there's no point of revving it to 8300 There isn't any power up there just noise.

Metal Head

true I agree, just wondering.

Hmm, Mabey I have insufcient oil pressure?

not sure, what code did you say you were throwing again? And when you reset the ECU it goes away or when you turn the key off then back on?

If the code only comes on while you're driving it and doesn't store, then it's a soft code. You'll have to jumper the ECU, drive until it throws the code, then it will show up with the code.

I had this happen with a code 41 once.

slayerfromhell212

the rev limiter is 7200rpm

Metal Head

Yes the code only comes on when I drive the car, but even though it doesnt show up a code, when I check for codes it throws the vtec code.

for a p06 yes it is. i hit rev limit in my old lx before and it was around 7200.

the ex/si (d16z6) redline is 7200...but not the rev limiter

for a p28 the revlimit is a little higher. ive never touched it in mine...but dont plan on it either.

as for the op.

im thinking there might be an issue with your ecu. try another one mabey?

A soft code is one that is not stored in the ecu when it happens. There are some codes that the ECU will store and not throw a CEL, which it sounds like you're encountering. I'm not sure why you'd be storing a code and only throwing a CEL when at higher speeds. You fix a soft code the same as any other code: find what's causing the ECU to throw it, then fix the problem. The only difference is how it shows up.

If you already know how to check for codes, then do it like normal, except don't remove the jumper, then drive the car with the jumper in until the CEL comes on. When it does, it will give you the code. It's a good idea to have someone else read it, since you'll be driving, esp when high speeds are involved.

That's what I'm wondering. If you're throwing a VTEC code, and VTEC is still working properly, the ECU may to blame.

haha, yeah, best said .

@ OP:
This post is a joke only b/c you're not providing us with any real info.

You don't know what code, GO CHECK IT, you're "pretty sure" and ****..damn dude, it takes 10 seconds to check a code.

Then you say you wind to 8.3k and u think the ECU is shot, if the ECU is shot the car wouldn't be running, and a rev limiter on a virgin P28 prevents you from revving up to 8.3k.

Kind of a paradox there, but whatever.

Metal Head

I simply said the ECU must be retarted. I mean comon, I can rev past 7500 rpms and NO revlimiter.

And im getting code #22 get it? Got it? Cool!

Marauder

CEL # 22 = VTEC pressure valve

You don't have enough oil pressure and the ECU shuts off VTEC.

Metal Head

@ 100 MPH, ok

So Oil pressure, what causes this? Oil pump falure? incorrect oil weight? Incorrect oil filter?



She smokes a LITTLE bit, but barely looses oil.

Metal Head

ECU= Retarted

Metal Head

Ricey, Yes, But I wanted to, in fact, fimnd out when EXACLTY vtec kicks.
So I installed an LED on VTEC vire. Took her for a drive. The light turns on @ 5200 RPMS. A very late engaugement. I thought it was suppos to kick @ 4800 ::shrugs shoulders::

I dunno if this tells you anything, but its a start.

schardbody

was that just barely mashing the throttle to get to the crossover point??? or was that wide open throttle. either way, it doesnt matter, its a SOHC vtec isnt even worth thinking about on a N/A sohc.

Metal Head

WOT,

But I guess, Civic tach= Not too acurate.

I would seriously take it to a dealer and have them diagnose it. I would not want to be fooling around at 100mph trying to check my CEL and have my oil pressure take a **** on me.

Marauder

Civic's don't have a specific crossover point. It can turn on VTEC anytime after 4800 rpms based on various inputs.

Change your oil and make sure its full. Might need a new oil pump. My civic has done it before, and all I did was do an oil change and it hasn't happened since.
