Mazda3 2010 CEL. Rainy day?

[derekl]

Hey guys.
I just picked up my car after getting some of my paint problems fixed and it was a rainy afternoon.
My car started to feel like it was losing power when i noticed the CEL and the traction light come on(only this light went away).

The dealership told me to bring it in on monday.
Should i take out my Injen Cai and put the factory airbox back in?
In the midst of deciding i went to check out if the filter was wet. I looked in the tubing and there were droplets of water (this normal for a CAI?). the filter wasn't soaking wet.

I will post a video later of the sound of my engine too cause it sounds alittle off.

Thanks guys!!

Typical rainy day blues of a CAI....

If you wish to keep your warranty, yes, you need to put your stock airbox back in. Unless you go to Dave Woods Mazda.

If the filter is wet and there is water in the pipe, chances are that is what is causing the problem. Take the filter out, dry it out with a hair dryer and then put it back on. If the CEL goes away, then you've found the problem.


But doesn't it come with some sort of shield to help keep the filter dry?

[derekl]

You mean the hydroshield? I never got one when i bought my intake.
I should invest in one.
It's just hanging around behind my bumper

Here's the video. Does my engine sound ..ping-y ?

Really? That's strange.... Yes definitely invest in one lol
Are you able to get at the filter? Can you take it off and try drying it out? Maybe you just need to take the whole CAI out and dry it off. Stick a hair dryer at one end on high and let it blow thru for a couple minutes. And then try drying the filter with a hair dryer.
Then re-install and see how it sounds and if the CEL stays on

[derekl]

Yeah i did that last night to no avail.
The CEL is still on.
Just installed the factory box back in.
CEL still there. =/

At this point, I think you probably have to go to part source or find someone with a port scanner and have the CEL cleared. Then start up the car and see if it comes back. If not, try installing the CAI again and starting the car up. And if it doesn't come back after that, then my guess is that it was from a wet filter / cai.

[derekl]

Should i do that? or just bring it to the dealer? Because i already have the factory airbox in there already.
Or would they not tell me what the CEL is a result of?
Will partsource do it for free or is there a charge?

[n00bMeiSter]

Part source does it for free. Dealer may charge you a "diagnostic fee" of like $100 (or so I've heard, don't quote me on that tho). Plus, part source is open tomorrow and dealer's aren't lol

Think of it this way. If you put it back to stock, clear the CEL. and it comes back, then you know you've got a problem for sure. But if it never comes back, then you've solved the problem.
And if you re-install your CAI and it never comes back, then I'd think you're good to go.

[derekl]

Yeah i was thinking about dropping by partsource tomorrow
Thanks!

Wouldn't i never figure out why the CEL came on?
Btw i also noticed weird idling. The car would normally click and raise the rpms from 650 back to 750. but now it's not a click but a short rev..
Is this rough idling?

[derekl]

Thanks for your help n00bMeiSter =)

[SomeGuy]

The click is the compressor for the air conditioning coming on. It would also explain the loss of power and whatnot...it's noticeable from the air conditioning. You'll probably get a stutter only when the code is thrown.

I wouldn't bother taking the intake out. Get the code read, it'll likely be something related to the MAF sensor. Dry things out then make sure you have a pre-filter, don't get on the throttle too hard in the rain, and possible tape up the vents in the wheel well to keep the filter a little more dry. The majority of the water comes from the gap between hood and fender though, so some people have been known to put tupperware on top of the filter of the injen intakes so that the water from there doesn't drip on the filter.

But i don't have the A/C on though. =/

[SomeGuy]

Is your heating vents set to defrost (or feet + defrost) ? That'll trigger the A/C condenser as well.

Nope. i don't have defrost on.

Is it only Injen and it's design placement that has water dripping from up top?
Can anyone direct me to a clearer picture of the tupperware on top the filter please =)?

[SomeGuy]

Injen since they point up lets the water get captured in the bend in the pipe. Some point more sideways, although my old AEM one still had the wet weather issues. My new cp-e in my MS3 seems to be okay though since it's tucked away better.

[derekl]

Don't really want to just use tupperware, though it'd save me money.
Is there some kinda plastic shield i could clip on top the filter?
Don't really want the hydroshield even if they say it doesn't obstruct the air flow.
Ideas?

[SomeGuy]

The hydroshields are like 20 bucks tops and don't affect sound or performance of the intake whatsoever. I wouldn't run an intake without one.

Just came back from partsource they got :

P0102
P0113
P0621

:whoa Woah.... They didn't tell you what each one means? The Part Source location near me looks them up for me too while I'm there.


Hmmm, I didn't find any starting with P0 but I did find these (I just replaced P0 in yours with P1):

P1102 Mass Airflow Sensor Signal Inconsistent with Throttle Position Sensor

P1113 Intake Air Temperature Sensor Signal (Dynamic Chamber) Circuit

P1621 lmmobilizer System Fault


EDIT:

After a little more searching I found these:

http://www.torontomazda3.ca/forum/showthread.php?25984-CEL-Code-P0113-Intake-Air-Temperature-Sensor-1-Circuit-High-Input


And then these:

P0102 Mass or Volume Air Flow Circuit Low Input
P0113 Intake Air Temperature Circuit High Input
P0621 Generator Lamp "L" Control Circuit Malfunction



And this one has a massive list of CEL codes and their meanings:

EDIT #2:

Did you have them clear the codes?

[derekl]

Hey Sorry i thought i finished the post up with the meaning of each code.
Thanks for going out and finding out what they mean!!!

Yeah they helped me clear it. and i have my Injen intake running fine without CEL so far.
I did however notice that water does in fact run right onto my intake filter when i was reinstalling it.
Can i just use some heat shield to deflect the water?

I understand that the first two codes are intake related but what's
"Generator Lamp "L" Control Circuit Malfunction" ?

Not sure, I'd say invest in a hydro shield. But maybe someone with an injen or similar cai can chime in.

Not sure about this one either, seems kind of strange.... Might want to call the dealership and ask them what that one means.

[derekl]

Yeah if anyone else has a Injen CAI for gen2 please chime in.
i think the hydrosheild would be fine with splashes of water. but when it rains there's gonna be a constant stream of water going on it..

[n00bMeiSter]

No one with a 2nd gen has an injen cai? Really?

[derekl]

I guess i was the first = (.

[cruisn76]

I am more inclined to say they might have disconnected something when they redid your paint (for whatever reason) and forgot to plug it back it. The computer in the car cannot compensate anymore and it throwing codes. Check for any loose wiring

Put a good hydroshield first off on the CAI, check engine light takes a while to go away, and if it doesnt, like others said get it zeroed out again. I also installed a 5x7 inch piece of black plastic with zipties in the bottom front left part of the bumper where air comes into the smiley face for the intake while driving. I went for a drive with this on, and later checked my filter and it was noticeably drier than without it. This helps keep the water from cars out or rain while driving, and the hydroshield is like a backup for the small amount of moisture which will obviously get in. Have never had an issue with this setup, highly recommend to settle these problems with a CAI. It helped me. gl and sorry to hear the problems you are having with your car from stock!

Yep! i picked up a hydrosheild from nextmod already :headbang
what's this plastic you're talking about? sounds interesting.

[Kiyomi]

i just made a custom litte shield for the front thats hidden behind the smile, so that only minimal amount of water gets in. just get a small piece of plastic the dimensions i said, put two holes in em on either side, get black tie straps and put them in the right spot behind the bumper, helps alot. lemme kno if u wanna c in person, kinda hard to describe
