Mazda 3 OBD CEL codes

Here is the list of the CEL (Check Engine Light) codes which are thrown and what they mean.

Perfect for troubleshooting and diagnosing issues when modding our little beasts :D

Thanks to The Pirate for finding this :2thumb:

This is gold! Where did you ever get this?

What's the process for getting the fault codes from the car?

Dash hawk or the like as far as I know :)

There should be a way you can make the CEL flash a binary code?

Here are some codes for CELs

They may suit 6 MPS aswell

Nice work Troy :2thumb:

I have this saved to my computer have not had to use it yet:whistle: (touch wood)

I have the ECU pinout aswell, but, it's too big to be allowed to upload to here.

Happy Motoring

that is very handy to know

thanks for the CEL codes.

however, the page 5 & 6 are missing.

anyone got the complete list?

thanks :)

Wondering if anyone has ever had a P0137 CEL & if there is a specific issue that maybe common that relates to this code. I'm speculating the 2 obvious things - faulty O2 sensor or the whole "car is running rich" thing. Just trying to include any other possibilities so when i take the car in for it's service soon i can give them a list to check off. BTW the car is performing very well and seems in good health. Only time it coughs a bit of black smoke is at WOT which i think is quite normal.

On a side note, has anyone developed a magic cure for the pesky P2096 CEL that all Gen2s tend to develop once the DP is upgraded?

As usual i would be grateful to anyone who contributes!
