Confirmed Cam Phaser Death? P0011

SG4247

Sorry, my bad.

Actually, it looks like Bank 1 (yellow line top graphs and blue line bottom graph) is very late.

Then bank 2 is a little late. Maybe not enough to matter.

So, you’re just gonna pull the front cover and check the timing marks, chains tensioners and possibly swap on good intake cam phasers. Definitely want to fix the galley gaskets.

There are scarf cut seals on the cam covers, that supply oil to the phasers, you could easily pop those out and inspect them.

You can also see if the tone wheel on each phaser is clocked to the bolts on the front of the phaser correctly. I have heard that they can move (although this seems unlikely).

I had two spare phasers I just sold. The buyer swapped them on, and still had the same code. His motor was super high mileage and still had original galley gaskets, chains and tensioners.
