Good morning! I have a 2006 Honda Accord V6 auto with 176k miles. I just did a throttle body/air intake cleaning and now I have a check engine light with these two codes. P0455 indicating I have a large leak somewhere but I see no leaks anywhere and P0507 indicating that the car is idling at a higher rpm, in this case about 1300 rpm. Last night when I was done working on the car I turned it on and no lights of any sorts were on and the car was idling at a steady 1000 rpm (cold start all the way to being warmed up) I turned it on just now this morning same thing happened but only a couple minutes after, the car started idling at 1300 rpms and i got these two codes. Help! Thank you for your time in advance!
For the P0455, check all the hoses under the hood, you may accidentally unplug some hoses. For the P0597, clean the IAC and throttle body.
Hi, wanted to give an update! By the way, I did mentioned I cleaned the throttle body/air intake (that's where the problems stemmed from). I unfortunately did not know there was a Idle Relearn Procedure for Honda that I had to do after cleaning the throttle body. So I did that and rode tested it under both stop and go and highway traffic speeds. The code(s) have never came back on and the car is running smoother than ever! I'm still curious as to why those two codes came on, but either way I still am going to ride it and make sure that within the next couple days or even weeks that none of those codes come back on. We'll see what happens but so far we're looking good boys!
thanks for the update, good info!
No problem, driving it as of right now (well parked right now as I write this lol) and everything is in good working order! I'll give another update on it in a week!
