Ok so I have this code P1381 and have found an article from Honda stating the Alternator could be a cause of it. So followed the service bulletin and came to the conclusion that the Cyl Position sensor is bad. Now the confusing part is that when I look up a distributor Im not seeing the number thats on my car now, so can anyone tell me if this is the OEM distributor or something that isn't even supposed to be on it. the number I found on the distributor is TD-81U and eveything I have found comes up with TD-80U or TD-83U I think thats one of them.
