P0017 + P0008 DTC Codes - Cause
So after spending a few days poking around trying to figure out why these codes were set I was able to figure out the cause. I’m posting this so that if anyone in the future has these codes it can either solve their issue or point them in the right direction.
So let’s start from the beginning my dad had tried fixing this issue by installing new camshaft sensors. That did not fix the issue. So then I decided to give it a shot, I looked at the VVT solenoids and the crankshaft sensor. I did find a piece of metal in the crankshaft sensor. So I cleaned it and ran it again. The codes came back so clearly the VVT solenoids and the crankshaft sensor were ok.
I decided to pull the bank 1 valve cover off to physically check the tension of the chain to see if there was any visible slack. To my surprise there was no slack no matter how much I wiggled it or pressed on it. So I was stumped, usually these codes are an indication of stretched timing chains. So what I did next was turn the engine by hand to see if there was any damage to the timing components. That’s when all the sudden the chain became extremely loose to the point where you could remove it if you actually put some effort into it.
So for those that are having a similar issue and have already checked the chains and they seemed okay. Give the engine a couple turns to see if the engine just stopped at a point where the chain was tensioned. Hope this helps someone out and doesn’t have to spend days figuring it out like I did.
