ok, so i went to check my cel with the self checker and when i shorted the 2 wire plug my cel just stayed on. it flashed on then off like normal without the paper clip. any tips?? thanks

H23_del_soul

mine does that sometimes, just turn the car off, take the wire out, put it in REALLY good and make LOTS of contact, then turn the car back on



edit :welcome to the CEL party

wolf95

tried that 3 times. same result..

H23_del_soul

hmmmm, have you reset the ecu yet? what year and obd0-1or2? 95 sol right?

wolf95

how do i reset an ecu? and i actually dont know what obd0-1or2 means. i've heard it alot but i never got a really good explanation. and ya, 95 del sol si

H23_del_soul

well 95 means obd 0 or 1, obd is on board diagnostics. the batt needs to be disconnected and take the top second to the right 7.5 amp fuse out of the fusebox under the hood. wait about 20-30 mins and then go connect everything back. then check the CEL.

wolf95

ok ill try it and let u know. thanks

wolf95

the fuse under the hood-did u mean the 15 amp ecu fuse? cuz there is no 7.5 under the hood

wolf95

ok so i reset it and it still stays on with the paper clip in...

H23_del_soul

hmmmmm, are there 2 different plugs to plug into?

slowhatchcali

what do you mean you shorted out the plug? its probably flashing still because there is contact between the two wires

slow96lude

there has to be contact between the two wires to read the code. If it is staying solid even with the plug jumped, then that means the ecu is fried. Take the top of the ecu apart and see if you notice and burnt resistor, caps or traces in the board, Top and Bottom

slowhatchcali

not necessarily, it can also mean there is no codes...

to the OP, does your car run?

slow96lude

If you jump the connector and the light doesnt come on, that means there are no codes. It could also be that the common grounds are not contacting properly.

slowhatchcali

no.. when you jump the connector, and there is no codes, it will give you a solid CEL.. at least thats how civics are.. or obd-1's for that matter

slowhatchcali

where does it say anything about having no codes= no lights? i couldnt find it..

Former User

This means all is normal and no codes have been thrown.

make sure you are jumping the plug then turning the ignition on

My bad slowhatch. The solid even after jumping can mean no codes It can also mean a FUBAR ecu.

slowhatchcali

yup it can go both ways.. with the first option being the best lol

slow96lude

Yea I will cross my finger for the OP. I was reading the thread link I posted and they jumped the ecu with car off and got codes. Also OP make sure you ecu/backup fuse under the hood is good or once you shut the car off to check the codes its reseting the ecu...

my laptops actin really dumb or id explain the whole story but long story short- my problem i was havin is gone and there is no cel comin on while i drive so were good now. thanks for all the help.
