SRI now have CEL

[turbotrix]

i have a 2005 2.3 , installed a SRI now get a CEL code.
im yet to pull the code on it...

any others with this issue or ways to make it go away for good ??
also fin that it now idles high as well

:complain:complain:complain
thanks

[laksman91]

reset the ECU (remove the neg battery terminal for like 10 minutes) put it back and let your car idle for a bit

might help out

[turbotrix]

thanks ill give it a shot

Did you undo the connectors holding the MAF harness from the battery box when you did the install? This could have caused the check engine light.

[turbotrix]

you mean the gray plastic loops on the out side of the battery box that hold the harness .. i undid them yes so the plug would reach the maf ..

other then that nothing else was undone other then the 2 plugs on the intake one for the maf other for what i belive is the air temp witch i just zip tied in new location .. cause there was no spot to mount it .

[turbotrix]

just pulled the codes got a p2177 and p2187

[stormin84]

there is a TSB on that code

http://www.finishlineperformance.com/pdf/mazda3/bulletin/01-006-06-1562.pdf

don't know if that helps

[turbotrix]

that TSB seems to be for codes P0172 / P2178 / P2188 ..
i erased the p2177 and p2187 codes .. will the car be okay to drive ?
from what i read on the net that its now running to lean .. and that people claim its the o2 sensor .. or could be caused by a air straightener that sits in the stock pipe .. by the maf ..

im kinda at a loss .. i dont wanna keep drivin it with a CEL ...

[stormin84]

its the maf sensor...i had the same problem with my 2005 gt when i put my cai in. they didn't know what the problem was, so i got rid of my car, and this tsb came out after.

[turbotrix]

changed the pipe and now gettin a p2195 code ..
what is goin on with this car ! drivin me nuts ..

laggy and stalls , at idle it searches ... i re set the ECU and cleared the code with my scanner .. ..

pulled the spark plugs they are white !

changed the pipe and now gettin a p2195 code ..
Changed back to stock?

If your scanner can to read the live data, read, after engine is warmed up on 50+ C(enters into closed loop mode), the air amount in gram per second at IDLE and at 2500 rpm ,intake air temperature ,LTFT (long term fuel trim) , and absolute engine load at IDLE.
If can't, read parameters from freeze frame after next CEL.

All these errors for "lean mixture". Spark plugs too.
If you got the last error on the stock intake, look cracks(more like that engine sucking air somewhere after MAF) , forgotten hoses or connectors. If you "over-oiled" the filter and SRI pipe is oiled inside now, clean the MAF and IAT.

[turbotrix]

no i changed the pipe from a 3" to a 2.5" pipe that the maf sits in ..
apparently the stock maf cant read a 3" pipe properly .

when i changed the pipe to the 2.5" it cleared the p2177 and p2187 but then i got the p2195 code .
theres no leaks or any thing i have forgotten ..

my code reader just pulls codes no logging ot real time data info

so im told is "purge valve" issue ..
car has no pick up at all just falls on its face .. pull the spark plugs they are nice and white

I had a CEL when I had my SRI installed and took it to the dealer and it was due to the purge valve. I had it replaced under warranty.

Not to thread jack but out of curiosity, did you still have the intake installed? They were okay with it and didn't blame it? lol.

[yearoftherat]

Running a MS CAI now.

Symptoms are like purge valve issue. Any leak gives the same symptom and such coincidence...
Are you sure your camshaft ventilation hose (with blue clips) inserted completely. It looks clipped improperly.

[sas]

Double post.Sorry.

[turbotrix]

yeah iv tripple checked every thing ...
i put the stock air box on and drove it all day and no check engine light .. and my plugs are tan again instead of white .. so its some thing to do with the SRI ...

There is nothing wonderful that you got the CEL with 3" pipe.
You can to calculate the difference thru squares. With 3" pipe the MAF will to show on 30% less of air than you have on the 2.5" pipe. Strange is that you had the CEL with 2.5".
If I remember correct, this is the stock size.
And this last error... The fuel system watched 25 seconds "lean" o2 sensor and hadn't time to raise LTFT and to throw p2187.
Very like on a leak. I don't know how the purge solenoid is constructed exactly, I think if vacuum helps to close valve it's possible that PCV is sticking opened.
I'm afraid you need to do some measurement with current stock intake to get what you can to do father.
Firstly, you have to be insured that PCM has a reserve to raise LTFT. You have to know where the top LTFT border is in your usual (most inspired) driving.
This LTFT should be less then +15%. At higher percents PCM will throw error.
CAI gives some performance. 10% percents is too optimistic number, I think 3-6 percents, though at 4000-5500 rpm this percent could be higher.
Add this percent to your top LTFT and you will to know the new LTFT with CAI. Take into account that winter LTFT is on a couple of percent higher.
So, your highest LTFT with stock intake should be no higher than 4-6 percents.
If it’s higher, then try to clean fuel injectors and fuel filter.
If you can't to have LTFT lowered, the next steps, like installing the aftermarket fuel pump or even bigger injectors are more appropriate for tuners, then for us ordinary mortal.
If maximal fuel trim is lower than zero, you can to install a CAI surely. Before installing, measure the air amount at IDLE and at 2500 rpm.
Also measure the exact IDLE revs. After installing the CAI measure the air amount and revs at idle again.
Now you can to check the new amount of air which MAF should to show.
It's simplified formula without pressures and temperatures, but should to work.
Air_new = Air_stock *( (RPM_stock -RPM_new)/RPM_stock )
To have intake cool , do all measurements with opened hood.
MAF should to read approximately this amount of air, maybe a bit more(I think on 1-2% ). If not, try to change MAF position.
As mechanical variant to change MAF sensitivity could be used flaps or shields, but you have to understand, that you may ruin the engine if such flap will be torn off.
More preferable is an electronic converter or it seems to me I have read somewhere that MAF could be recalibrated by WDS tool (or it was a dream). And again, it’s more for tuners.
Then, do the check of air at 2500 rpm to be convinced that you have the same air amount as stock or a bit more (on 3-6%).
As you can see, the CAI is not so simply, on some cars there is much to do.
