So I have three codes that come up here recently on my 90 integra. The ect, tps, and the iat sensor. So i replaced them all and every time I try to clear the codes they come back.
They all are getting voltage like they should. Just not sure what to look for next any help would be appreciated thanks.
Or any idea if those sensors go into the main relay. Pin location on ecu would help too. I’m running a hondata s300 equipped ecu
