swap in a known good under hood fuse box if the cel come back on with the same code then its a short some where in the system

It's possible, either way that's not such a good idea to hook up the fan like that.

yeah i know it was temporary until i hooked it up lke oem , because i bought a 13" slim fan.

Aha, so did the CEL come on before or after installing the fan?

[zct95]

well i think it came on after installing the fan because i noticed the code yesterday because my car started to have a lumpy idle and the my cel light came on and when i pluged the computer i read code 20 ELD and code 10 that the car was overheating. now when the temp went back to normal the cel light turned off but the code 20 still apeared, and i erased the code but after some time it appeard but the cel light did not came on , like a "silent code", tomorrow i will try what dina said and some other suggestions i found on other sites.

oohh and wondering if the gasket or the head is bad , when you turn the car on the coolant will start to bubble because the cylynders are pushing compression to the coolant system.

Sounds like a bad head gasket to me.

well checked everything from top to bottom and discovered that it was throwing the code because the ground box had the cable from wich the ELD connector recives ground damaged, I repaired it and did some test like the manual tells you and now it is as good as new.
