I HAD PROBLEM WITH engine lights before. now , i fix everything but this light won't go away.. i've tried to take out battery plug.. and it worked for like couple of dayz, then engine lights came on again... is there any way i can make it disappear ???.. i know for sure i have no problem on my car...and i don't wanna spend money just to erase the light thing... so please help~~

 

If you disconnect the positive wire of your battery your ECU will be reset.

Or you can open your fuse box, and disconnect the yellow plug, or the if you have a big fuse standing alone, disconnect that for like a minute and plug it back in.

hope it helps

 

Translation:

1. your car is not running
2. disconnect your battery for 30 seconds
3. reconnect your battery
4. start your car and let it idle in nuetral (no revving) for 5-10 minutes.
5. put in your radio anti-theft code
then you are good to go...

after resetting ur ecu..if it goes on again, uve got something wrong..start with O2 sensor s

 

you can narrow down the code by jumping the service connector. if it is in fact a 02 code, you will get one long blink of the check engine light. find out the exact code, then go from there.

 

heres how to check the code if you dont already know

To check the code, Take off the passenger side kick panel and look above your ECU (the metal box). find the green rubber housing
with a blue connector (looks like the end of a telephone cord). Get a piece of wire like a paperclip, and
bridge both connections. Now turn your key just before you have to start the car, watch your CEL and get the code.
If the CEL blinks fast, that stands for 1, 2, 3, etc. If it is a long blink, that stands for 10, 20, etc. The code
will recycle, just in case you don't get it the first time. also, there could be multiple codes.

 

correct, it's late i wasn't thinking straight.....

 

how do you know for sure that there is nothin wrong. if it goes away for a few days and then it comes on agian then there may be a problem that needs to be fixed. anyway i was taught that to reset your ECU unplug the back up fuse in the fuse box under your hood (7.5). plug it back in after a minute or so then start your car and let it idle for a while 10 minutes or so. DONT PUSH ON THE GAS. then turn your car off and start it back up.

that is what i was told but ppl may have a different way of doing it......

 

you can also reset your ecu by pulling the 15A ECU fuse out of the fuse box in the engine bay for 8 sec.

 

This is the correct answer...
