THE MOTOR IS ON MY 92 CIVIC HB. THIS IS THE 3RD ECU THAT IT BURNS OUT. I AM CLUELESS WHEN IT COMES TO ELECTRICAL WIRES SO PLEASE HELP

 

it could be alot of things but check your grounds, and make sure no "hot" wires AREN'T touching a chassis ground, or worse your ECU case. also make sure all your sensors are plugged into their respective plugs on the harness. wrong sensor in a wrong plug can fry transistors in a hurry.

 

yup check all that stuff as stated above... also do you have any cel's?

 

OK I CHECKED MY ECU PLUGS AND FOUND THIS

hey i have the same problem...


except my plugs are perfect....im clueless too.

i AM throwing a code 41 though....

could it be because i dont have the o2 sensor plugged in? like would not having the o2 sensor plugged in fry my ecu?

 

I PUT A SCREW OF WHERE THE BURN PART IS AT

 

OMFG!

thats exactly where mine is at too!

did you also do a swap + 5 speed conversion?

 

What number is that? I know if you cross IAT and EVAP you fry i believe Q31. I think its in that area. But thats a bad picture you have.

Had to change EGR to EVAP.

I JUST OPENED MY ECU AND YOUR RIGHT IT IS Q31 THAT BURNED OUT.

 

Make sure your IAT sensor and EVAP sensor plugs are not mixed up.

OK WHERE ARE THIS PLUGS LOCATED AT

 

On the respected sensors hopefully. IAT on the manifold, EVAP is usually on the back more on the driver side.

thats how it blows mixing up them to sensors.ive came acorss a few obd1 ecus with that same part blowen.if u try to chip it with that blowen part it will throw a soild cel till i fix it,i can fix it for 30 bucks u pay shipping.ill buy that ecu from u if your going to trash it.

 

It is easy to mix up the IAT and the IAC they both use the same clips did you have a CEL? thats just weird, I really wouldnt be to worried about the oil in the plug oil dosesnt conduct electricity like water or antifreeze would, but dont qoute me on that i could be wrong. You should look to see where it is coming from.

 

OK I FOUND THAT THE WHITE PLUG WAS ON THE BLACK SOCKET AND THE GARY PLUG WAS ON THE WHITE SOCKET WILL THAT BE THE PROBLEM

AND WHAT KIND OF ECU CAN I USE
