Official 2010+ Mazda3 Rollcall

[2010axela]

This is coming from my knowledge of emissions on my P5, which uses two catalytics. You probably did one of the following:

1. Forgot to reinstall 2nd o2 sensor or busted it.

OR

2. You didn't do any modifications to the 2nd o2 sensor. In my p5, the 2nd o2 sensor checks to make sure the emissions system is working properly. When I put my header on (removing the 1st cat), I had to modify the 2nd o2 sensor using two spark plug non-foulers which brought the sensor out of the exhaust stream. The other option was the MIL eliminator fix which involved rewiring.

Check around and see if #2 is required for your car's mod. I'm betting it is.

hey brother,
could u pls tell me more in detail about the mods to the second o2 sensor. im not quite sure by what u mean on how to mod it?
thnx

Wow, thats' a lot to do in one sitting. I would have put one thing on at a time to see what happens. DPs can cause a CEL due to the o2 sensor going wonky. The second cat (highflow/race pipe) should not be an issue because the o2 sensors do not monitor it, but can almost guarantee your problem is the DP.

I have read that intakes can throw a CEL if the MAF is damaged or if it's not reading properly.

Just for fun, reset your ECU (disc the battery, pump the brakes 20x then reconnec). If the CEL comes back connect a Dashhawk/Scanguage or something like that and start getting some codes for us.

the code it gave me was p0171 "system to lean bank 1"

p0171 means your o2 sensor is reading your AFR/emissions as "lean" or too much air. You need to somehow bypass the o2 sensor and/or hit the ecu to trick it. I've not gone that far with my MS3 yet, but I'm sure tons of other knowledgeable people will quickly chime in.

Again, this is for the p5. Though it may also be what you need.

The fouler trick should work. The o2 in the cat typically reads the level of emissions or clean air to make sure the cat is doing it's job. By extending the sensor out of the direct path of exhaust flow the ecu won't know the difference. This has been used on numerous cars/applications for god knows how long.

Keep us posted as to your results.

Hey Mazdas247!

Just bought a 2010 Mazda 3 i Sport 4 Door 3 weeks ago--my very first NEW car. So far I'm loving every moment of it EXCEPT for the CD Player which, alas, never worked.

I'm getting it fixed under warranty this week (first appointment is tomorrow...) so fingers crossed that it'll be a NO HASSLE situation.

Thanks for having me!

Congrats on the car...

You'll have to buy the OEM from the dealer or perhaps a seller of genuine mazda parts. Prepare to pay a pretty penny for them.

Taking apart your headlights is really not that scary. Set aside a weekend to do them right. Darkspeed3 did an incredible job with his. Here's a link to his thread:

Well, took my M3 in two days ago. The guy said he'd need to order a whole new radio and that Mazda forbids them from opening anything inside the car up if it's still under warranty.

Hopefully that means I'll be enjoying tunes again early next week. He also said it should only take about 30 mins to swap the radio (so I don't need to get a rental), but I'm still a little scared that the new one will creak and squeak. I've had bad experiences with replaced radios before...

So far, my first service experience has been positive!

We call Mazda3s, Mz3s on here since M3 sounds like a bmw, just for future reference

Welcome!

Gen 2 MPS Downunder

Hi all,
New to this forum, a member of Ozmpsclub. I have my second 3MPS (Mazdaspeed 3) since November last year. I had a Gen 1 Cosmic Blue to start with.

 

[El Speed3]

Hey!

Nice rims!! Welcome!

I didnt know aussies had the UK spec cars (Im assuming this from the name you wrote), I love the MPS badges on the front bumper and the back...

 

[ASmitty]

Hey forums, just traded in my 3.5 MSP for a 2010 Veloctiy Red MS3. Glad to be part of the new community.

Thanks for the tip! So, I got my Mz3's radio replaced and everything is great...except you can clearly see where the tech shoved in a flathead screwdriver / similar tool to pop off the radio cover.

;_;

Well, technically the scratch is on the face plate for the climate control, which is right beneath the radio faceplate. It's pretty small...my girlfriend says that only /I/ would notice such a thing but I'm still considering asking for them to replace it.

Will try to post pix later, but what do you guys think? Barely a month old.... (sad1)

Terrible pic, but it's the best I have so far.

My MS3 with mods

Hello everyone... here is pics of my Celestial Blue MS3. Purchased mine in Nov of 09, this is the second MS3 I have owned. Already have the Mazdaspeed CAI and Cobb TIP installed. I kept the stock rims from the 07 MS3 and put some Blizzaks for the snow.

I dig the color, but I personally like the stock 2010 wheels better. Cool to see you got another MS3

 

[JTMS3]

I got the 2010 wheels in the garage just waiting for spring.

Quick one.... What ms cai did you use? Was there any "fitment" issues?
I have been told that the previous years won't fit!?
