P0018 code
Hello all,
My engine light is on and I have code P0018 - 001 - Incorrect Correlation. at this time I don't have any other codes for the engine. It does idle a little rough at times and runs smooth above idle. I'm wondering what sets this code off is it the main chain tensioner, and guides or could it be left or right or both cam chain tensioners and guides?
I started the engine and had the occasional tensioner rattle but this time followed by the sound of something rubbing up against a chain. shut the engine off and restarted the noise wasn't there anymore and then the check engine light came on. I was wondering if cam chains, tensioners, or guides could be the cause, and if so could they be changed in the car if needed?
