How about for the 06 Speed6? Do you have the CEL code listing?

 

[Koya]

2 Jax6S
I looked at link and there is no description what causes it.
At mazda workshop manual I found all descriptions what causes each CEL. And how to fix it fast if it possible. So once again - do you need official workshop manual or not ?

PS. I have Speed6 too...

Can u send that to me Koya if you have that manual for the 2.3 I-4. That would be really helpful. Thx

 

[techtv04]

<strike>Is there another list of codes since mazda 6 tech will be no more.</strike>

never mind i see them

What about Lean codes????????????

 

[Bluemikecheck]

If anybody wants or need the Shop manual for the 03-05 mazda 6i MZR email me. I have it in PDF. i will forward it to you. It lists all the CEL codes and how to trouble shoot and repair them.

Hello I have a 2004 Mazda 6 the 2.3 litter and i read your post and i would like to know if you can sent me the repair shop manual for the codes. I thank you in advance

 

[Beaslik]

codes

Got P0661 and p2187 codes. If someone has pdf of manual still for diag. and fix on these codes I would sincerely appreciate it. My email is [email protected].

Thanks

DTC error codes

Has anyone seen codes or heard of codes U2616, U2618, and U2619
for a first gen 2008 mazda 6i

U codes are generally newtwork type codes.

Trouble Codes is there a list? - Mazdaspeed Forums

Looks like they may be TMPS related. Any recent wheel changes or issues?

 

[krayzieray]

No new wheels or tires. I just been researching these codes and yes it looks like 3 of the 4 TPMS sensors hit the brick. I've had a problem with them for awhile, were the TPMS light will blink in the instrument cluster but all tires are within specs. The TPMS light(on clock work)goes off when driving home from work everyday, so theirs $200 in replaement parts.
Thank you for your assistance

Hey all,

I just replaced my catalytic converter and the o2 sensors. My engine light at first stated my catalytic converter needs to be replaced. now I am getting code P0302 and P0171. When I went to Autozone the solution was to "reprogram the ECM (Engine Control Module)". Any idea on how to do that? Is it simply just unplugging the battery, waiting 10-15mins and plugging it back in?
