I took my car to get inspected today and when they went to do the emissions test and put the plug in under the dash. They said they cant get a signal from the ecu. They also tryed a scan tool and cant get a signal from it either. Any one kow how to fix this. I just put a engine swap in it and its a 97 civic ex. ---

hmm the only thing i can think of then is if it’s obd2a and you converted it to obd2b then the pin for the k-line (communication from ECU to data link connector) may be in a different spot at the ecu? not positive though, just something to check. ---

Its obd2 still its a b18c. Im going to check the k line today. Im not sure how to check if theres power to the plug they said the machine turned on but it could not get a signal from the ecu. Its supost to be obd2a but not positave Its says p72 on ecu. You think H motors could have sent me a bad ecu? ---

when i got my del sol “inspected” that tailpipe probe went right in the muffler of a brand new pontiac. anyway did you have to use any sort of jumper harness for the swap. like it was mentioned before i think its the whole obd2a to obd2b thing. happened to my buddys 96 hatch and he put the same swap in. ---
