2004-2009 Mazda 3: Mazda 3 Check Engine Light P0126 & P0128

Tue, 09 Oct 2012 19:20:24 -0700

The two codes from the check engine light are: P0126 & P0128

Here is what I found according to my research:

P0126 is either replace coolant temperature sensor or replace the thermostat. According to my research, the issue that 99% of people had from this code was that they needed to replace the thermostat. Once that was replaced 99% of the people said that the light turned off and that they did notice a difference as to how the car ran better than it did before. Some people said that its about a $100 including the parts and labor and no one should pay over $200. People said that they were even able to replace it themselves (if you can get under the car). The thermostat part is: LF7015170. I looked it up online from a Mazda parts dealer and its about $45-$50 depending on which parts dealer you buy it from. I'm sure I could even find it on ebay for cheap too.

P0128 indicates that the computer is detecting that the engine is not reaching operating temperature within a reasonable time after startup. I am guessing that this relates to the issue with the thermostat?, but i'm not 100% sure.

CAN ANYONE GIVE ME MORE ADVICE/INFORMATION AS TO WHAT I SHOULD DO? HOW MUCH IT WILL COST?

2004-2009 Mazda 3: What would cause a knocking noise when downshifting a manual?

Sat, 30 Jul 2011 05:53:22 -0700

I hit a pothole a few weeks ago which may or may not have had something to do with my problem. At first I had knocking/banging when backing up (especially up a hill). The shop rebuilt my transmission, replacing worn out bearings and clutch and resurfacing the flywheel. Well now I still hear the noise, not as loud, when downshifting. I also heard it once when starting the engine.

My father in law found a metal strap with grease on it in his driveway and I am pretty sure it goes to my car, but the shop says no.

Also, the said the engine mounts were fine.

This is a 2008 Mazda 3 2.3L manual with 120k+miles.

2004-2009 Mazda 3: Repair of sunroof so it will close/open

Sun, 16 Jan 2011 16:41:23 -0700

My sunroof is stuck in the 85% close position. Pushing either the open/close switch you just hear a 'rattat-tat' sound and the sunroof remains in the same position for most of the time. Some times it does move half an inch either way but that's all. I need to get under the headliner and be able to see if there are any small bolts loose/missing and what the track assembly looks like. Can you help and by chance also provide me with an excerpt from the factory service manual?

Update

Sure. I thought I included it. It's a 2006 Mazda 3 and is a 4dr. Can you also find info for removing a portion of the overhead headliner in order to be able to work on the sunroof motor and track assembly?

Thank you.
