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

Fri, 19 Apr 2024 18:46:10 -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, 99% of the people who had this code needed to replace the thermostat. Once that was replaced, 99% of the people said that the light turned off and that they noticed the car ran better than it did before. Some people said that the repair is about $100 (including the parts and labor) and that 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 it's 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?

1998-2003 Mazda Protege: Heater only blowing out front vents, no heat to feet or defrost. Why?

Thu, 01 Feb 2024 12:17:23 -0700

Heater working but only blows out front vents. No heat to feet or defrost. Before replacing Heater Control Unit, it would only blow hot air from front vents- With this replacement it will now change from cold to hot and the air flow pressure does change from the front vents when changing the setting dial but there is still no air at all to feet and defrost. Can anyone tell me if there is a louver or valve that could be jammed and where to locate it? Or what else to try? Thanks!

1998-2003 Mazda Protege: I think my car is losing power to 1 cylinder.

Wed, 19 May 2021 02:22:21 -0700

'99 Mazda 323 Protege.

Manual, fuel-injected, 4cyl.

Engine code: CE04D16

ok so just recently started having troubles with the car. It ran fine then all of a sudden I lost what felt like 15-25% power, and the engine felt like it was shaking a little.

When revving, then engine would shudder. Idle rev went from just over 1000 to around 500. there was very little pickup when increasing speed. I can only assume it lost a cylinder. Now for the last couple days it has been jumping backwards and forwards, from regular to slow.

What is the problem, can I fix this myself, or do I need to take it to a mechanic?

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

Wed, 14 Jan 2026 11:36:22 -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?

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.

1998-2002 Mazda 626: 2002 Mazda 626 Car shakes when stopped in drive, neutral or park.

Thu, 19 Jul 2018 08:53:48 -0700

Original Post: 2002 Mazda 626 4 cyl with 85000 miles

I have a 2002 Mazda 626 4 cyl with 85,000 miles. It has a bad vibration when idling, Once the car starts driving the vibration is no longer noticeable. My car idle is set about 650 RPM at a stop in gear. If I rev my engine to about 1000 RPM the vibration smooths out. When at a stop I notice that using the AC or turning the steering wheel seems to add to the load and the RPM fluctuates sometimes to the point where I think the car will stall. The plugs, wires, firing coils and distributor are new (replaced 2 months before this problem started) all the motor mounts are new, new brakes, belts, tires and 4 wheel alignment. New air filter, oil and filter and the transmission fluid is full. The vibration actually got worse after I replaced the motor mounts. Any ideas? I cannot find any loose or bad vacuum hoses... one hint... the vibration started when I had the air filter replaced. It would idle rough when I was in drive with the brake on but in neutral or park the vibration would cease. After replacing the motor mounts (3 were busted, replaced all 5) then the vibration became worse and is present in all modes (park, neutral or in gear). Could something have clogged the Mass Air Flow valve when the tech replaced my air filter? By the way... the "check engine" light is not on.

2004-2009 Mazda 3: Is the AC clutch on a 2008 Mazda Mazda 3 replaceable?

Fri, 07 Feb 2025 12:13:39 -0700

So my girlfriend has a Mazda 3 2.3 sport, about 3 months ago the ac suddenly stopped working after a road trip. That being said I'm a mechanic at a local shop but much to my dismay we sub contract our ac work. After countless hours of electrical testing pressure checking and tons of homework I found the ac clutch was seized. Does any one know if the clutch could be replaced in order to get the ac going again or is it a complete ac compressor job?

My check engine light is on so I did a code check at my local parts store, the scanner said my problem is an intake air temp. sensor. My problem is I can,t find it. Please help. The reason I had it checked is because it takes me 30 min. sometimes to get it started.
