P1259

I’m aware this has been covered a million times extensively but I’m curious if anyone has ever had to replace their ecm for this damn code. I did the wiring diag however I’m a tiny bit unsure how correct I did due to the service manual sometimes being a bit confusing on whether or not it want’s a connector connected or not. I replaced my entire spool valve assembly with a Honda oem part. It has fresh oil less than 100 miles. I’m kind of leaning towards ecm but I’m really hoping not and was wondering if there’s anything else worth checking before I dump 400 dollars into an ecm and keys.
