b18a1 code 9 CYP sensor
b18a1 swapped ef civic sedan. obd0 to obd1 conversion w/ jumper harness on ecu and dizzy.
I have a code 9 that will not go away no matter what I do. I've replaced distributor with a known good unit. Checked all connections to the ECU and through jumper harness to my best ability. Reset the ecu of course. I've had a couple people tell me to check the grounds for the CYP but I don't know what or where those exactly are. Anyone have tips/ideas? Also does anyone know the difference between CYPP and CYPM pins?
