I strongly agree, very common on the VQ35DE, not so much on the VQ40.smj999smj wrote:The only time I've seen those codes on a VQ40DE is when the primary timing chain was installed a tooth off. They used to occur more frequently on the VQ35DE engine and they were most often caused by bad intake valve timing actuators and/or low or sludged oil.
thanks for the clarification on both advance and retard of cams causing 21 and 11 codes to pop. When your tenshioner collapsed did both p0011 and p0021 codes pop? What orher codes came up?smj999smj wrote:Codes will set for out of time, retarded or advanced. With both banks triggering codes, I would suspect that it would be off at the crank. ............ I had a bolt break on my primary tensioner which caused the tensioner to drop back against the inside of the cover and the chain to slack; it made a hell of a racket as the timing chain smacked against the upper chain guide!
