Ok so i just got a 95 integra... the car use to be vtec but the motor was completely rebuilt and a non vtec head was put on...the car did have s300 but the guy i bought the car off of wanted to take it so he gave me a p28 ecu to get teh car home on... i then changed it to a p75 obd1 ecu. The car runs fine and idles good. The check engine light came on because of a coolant temp sensor. I fixed that but now i cant reset the CEL i tried the battery, pulling the fuses and taking the ecu out and putting it back in. i did a self test and the CEL just stays on the dash instead of flashing. Any ideas how to get the CEL off when the car is running?

soo i pulled off the ecu and looked at some of the wires and this is what i found..
brown with black stripe(Logic ground) connected to blue/yellow (CKP ground) to orange with blue stripe (TDC ground p-side) to orange (CYP sensor p-side) white with red stripe (Interlock control unit A/T replay)



The blue with red stripe (starter signal switch

 

im pretty sure thats normal. i found plenty of those jumper terminal things when i re did my stock ls's loom.

 

Normally if you have the service connector jumped and your CEL doesn't flash it's because of a bad ECU or fuse.

 

The uninsulated "crimp" connector shown in pix #2 is a standard connection used by Honda/Acura, [and other manufacturers] it should have been covered with blue tape.

The only white/reds I can find are the ones for the heated O2 sensor, [O2S] and the alt., [ALT F] and the brown/black is connected to the "shields" of those leads, not the leads themselves.

As riotchild mentions, a solid CEL is an indication that the ECU/ECM is bad. 94

 

the CEL did flash it flashed to show me the coolant temp sensor was bad so i fixed it and now it doesnt flash... whats a ECM? and wheres the fuse for the ecu in a 95 teg?

 

ecm=engine control module
fuse should be in the under-hood box
