New vvt cam installed big problem now. Please help

[James DeMoss]

One time I had low oil pressure after cam install due to getting a bad cam retainer plate seal that blew out. also something to check on LS engines.

Nice info. I also heard the p0016 code could be from loading an 'empty' vvt cam into an engine. There is no oil in it or the phaser to accurately retard or advance timing. So in short, after a cam install or phaser limiter, the code p0011 and p0016 are perfectly normal and ok. A tune will fix them.
