I know theres dozens of threads on CEL's but none seems to help me out. One day after i got subs the CEL turned on and stays on. Its not the gas cap.Even when i restart the car its already on (CEL).ANyone have this problem b/c i only have seem to read people's CEL only turn on for a couple sec's.
Sorry its late and im tired of searching.
Anyone know what I can do?

Thankz to whoever replys

 

okay since no ones answering maybe b/c you dont understand

my CEL is always on when i start the engine anything major to worry about like i shoundnt drive it or something

 

Have the dealer check it. The CEL can be from 1000 different things. Also you stated it happened after you got subs, did you put them in? How are they hooked up? Does the car seem to be running right?

Just have it checked by the dealer.

 

you think it the car can wait 1 week before it can be check,car seems to be running like normal

thankz 2000 for the reply

 

You stated that your CEL came on after you installed subs. Your subs could be pulling too much current from the system and causing a low volatge fault. Does it do it when your only when your system is on? Could you have accidentally grounded something that shouldn't have been? I wouldnt drive around to long with a CEL that stays lit. Have Mazda check it out.

 

I am an old fart and not so familiar with the latest trends, are subs speakers? Does the name imply powered sub-woofers?

If these are being supplied power from the vehicle then obviously the cause of your MIL (CEL) is current drain by the woofers being mistaken for a fault.

However, the audio has its own diagnostics, independent of the MIL. Which makes me wonder where the heck you took your power feed for the subs from? Where ever it is, change it to a direct feed from the battery. Start the engine and stop it again 3 times after you have rewired it (when hot, otherwise you will flood it) to clear the MIL. If the trouble code is a major (OBD) one it will stay in the PCM memory and will have to be erased by the dealer.
