96 prelude emissions problem...urgent help needed!!!
friend has 96 prelude non vtec si. swapped in h22. runnin a 97+ h22 ecu...went to try to get emission...emissions guy says the dlc(think you plug into to check emissions)...is not connecting/reading or summin...is this because i dont have the obd2a p13? only rear it was made was in 96. im wanting to know if thats causing the problem before i drop 500 on the 96 obd2a p13 ecu! thank you
reps for help
oh yeah would just have someone pass emissions but he lives in tennessee
hmm... so is it an OBD1 motor with OBD2 ecu? Running a jumper?
its a obd2 car with a obd1 motor using a obd2 ecu but not the right one...no jumper...it did have ecu jumper to obd1 ecu but that doesnt work for emission obviously...im bout to buy a 96 h22a vtec ecu the only yr thats obd2a .... there is a 97+ prelude h22 ecu in there now but when my homie goes to get emission done it say dlc not reading or summin...so im thinkin its the ecu..
Have you checked the connection of the plug? Could be something that simple.
could be...but im 99% its plugged good
you need the 96 si vtec ( h22 ) ecu . i had the same issue with my 96 accord that had a h22 swap. for reason obd1 motors dont like to pass emissions on obd2 ecu's. unless you completely convert the motor to obd2.
About to approach beast mode
aaahhhh....thank u very much!!!
as long as you dont have any check engine codes and the ecu passes its readiness codes it should pass. The obd1 motor could be preventing it from passing the readiness.
so will this obd2a h22 ecu fix or will i have to convert the whole motor to obd2? i think he told me he has 1 o2 code thats it.Originally Posted by Batlground
fix the o2 code and try again.
