#4242 of 4531 Re: Speed3 Fuel Injector noise [roadburner] by networkguy Mar 02, 2008 (8:21 pm)
Replying to: roadburner (Mar 02, 2008 5:36 pm) I later had the shutter valve recall, so that probably fixed the problem for good.   That's what they replaced on mine prior to issuing the recall. I'm thinking about the Mazda CAI. I'm too busy/lazy to pull out a 3rd party aftermarket part before a dealership service appointment. I was thinking about the cat back exhaust too, but I've heard the stock exhaust is actually pretty good. Replies to this message: roadburner (Mar 02, 2008 8:28 pm)

Replying to: networkguy (Mar 02, 2008 8:21 pm) I'm too busy/lazy to pull out a 3rd party aftermarket part before a dealership service appointment.   I'm going to check with my dealer and see if the Cobb will cause any warranty hassles. I like the Mazda CAI but for the fact that you have to pull the undertray and the wheelwell liner in order to access the filter for cleaning...   I was thinking about the cat back exhaust too, but I've heard the stock exhaust is actually pretty good.   Me too; based on what I've read on some of the Mazdaspeed forums the stock MS3 cat-back exhaust is more than adequate until you start cranking up the boost- which is something I don't plan to mess with.
#4244 of 4531 Re: P0715 Input/Turbine Speed Sensor Circuit Malfunction, any ideas? [mazda by mazdazoom Mar 04, 2008 (8:30 pm)
Replying to: mazdazoom (Feb 19, 2008 6:52 am) I realize I am responding to my own post, but I thought someone might find this useful. In regards to the 0715 error message Mazda agreed with me that it was the "speed sensor" located near the bottom of the tranny near the firewall, or the pulse generator located at the top of the tranny right under the battery box. Well I replaced the speed sensor myself and I still had the problem. So I went out and picked up a pulse generator (another sensor similar to the speed sensor) and replaced it myself. BINGO, that was the culprit, and the tranny is shifting better than it ever has. So just an update, if you get the P0715 error, it is either the speed sensor or the pulse generator sensor, I just replaced both sensors for good measure, $160 total. Save yourself the $200 in labor and swap it out, took me about an hour with test driving. Replies to this message: nocents (Apr 10, 2008 6:40 am) mazdazoom (Apr 10, 2008 7:18 am)

Replying to: roadburner (Mar 02, 2008 5:36 pm) What all did the recall entail about the shutter valve, and how do I go about finding out about having mine checked out? My CEL has been on for a few months now, and when I had the code read, I believe it said something about the shutter valve, and then once about the upper intake runner closed or something to that effect.

In most cases the valve is replaced and the PCM(engine computer) is reflashed. Replies to this message: tarheelschik (Mar 06, 2008 6:12 pm)
#4247 of 4531 Speed3 Turbo Failure by comet2003 Mar 06, 2008 (4:09 pm)
Hello all MazdaSpeed3 and Mazda3 owners.   I own a 2007 Speed3 with only 6500 miles which began belching blue smoke. A trip to the dealer resulted in the dealer being instructed by Mazda Tech to hold my car and order a new Turbo. The replacment Turbo is on national backorder at this time. I've since learned that my car is among a number of Speed3s which are requiring replacment of the Turbo.   I have not seen any postings of this problem here, so unfortunately I guess I'm the first to report this here at Edmunds.

Replying to: comet2003 (Mar 06, 2008 4:09 pm) You could drive the car this way I think. Sounds like the bearings are loose in the turbine or the compressor side. This is often caused by poor lubrication or very dirty oil--but rarely at this low mileage.
#4250 of 4531 steering, suspension, alignment... by mazdrvr Mar 06, 2008 (5:41 pm)
Hi, i need your guys help again. This tire blowout incident is becoming a costly headache!!! After a week i got my car back & was recommended to do a alignment. The impact of whatever the tire struck (or vice versa) was so hard they said there was a hole in the tire (explains the bent rim & bumper damage). The front where it happens makes a pop, "boing" noise when the wheel is turned lock to lock. Also on that side, when i drive & go over certain bumps, you hear & feel a knock. I had a alignment done today but still noticed some things and wondered if someone could tell me if i might be so i can have it checked & hopefully fixed...   1. steering wheel still not centered, turned slightly to right & hear a "rubbing sound when i turn it. 2. when i drive & go over certain bumps, you hear & feel a knock. 3. makes a pop, "boing" noise when the wheel is turned lock to lock (something in strut, suspension?). Much appreciation & Thanks in advance!! Replies to this message: roadburner (Mar 06, 2008 7:49 pm)

Replying to: roadburner (Mar 06, 2008 10:47 am) Ok. Thanks for the info. I called the Mazda dealer that is around here, and they ran my VIN, and they said there are no current recalls for my car, and that the only one they have on file that was for my car was back in 2004, and that was for an air bag sensor that they fixed already. So everything checks out I guess. I just need to find out what is going on with the stinkin CEL now!
