Help me. Would you show me your camshaft phasers ?
Pulled both cam covers off the g37 (2013 with 52k miles) to inspect the cam phasers. Why ?

Long story short. --> The g37x went dead 2 blocks from the house a few months ago - no warning. Code P0340 popped up. Only code.
Replaced Camshaft Position Sensor on Right (passenger - Bank 1) with new one from Infiniti.
Car would just turn over fine but never start (with battery coming off a full charge and checked good).
Pulled CPS connector off - car started but ran very rough. Towed it to the dealer. Dealer says he needs $6k for new engine. I say f**k you all. I'm outta here.

Check for similar problem online and found the link to Jim Wolfe Technology. http://www.jimwolftechnology.com/wol...derslipped.pdf



Can you guys look at my intake cam decoder ring and say its moved any ?? =-This is the intake side cam sprocket the one which threw the code.
The exhaust side looks like this:


just wondering if anyone has had experience with these things shifting and having to replace them.
Thanks !

No experience. And we can't tell unless both the rotor and the front cam lobe is visible.

Based on comparing with the photos from JimWolfe Technologies - I think both of the phasers may have shifted ???

I'm not sure. I dont have anything else to go off of.
Looking to see if I can find any good shots from youtube vids.
- or if anyone has their motor taken apart and could post a pic or two.

Update on an old thread. I feel like whoever can post pictures of their cam encoder wheels at TDC would help the rest of the community tracking down on this pesky code.

I been getting a pending 0021 and 0524 code for a year now, after it first started i did the galley gaskets. Mechanic said everything else looked fine. Worked great for 2 months then i got the pending p0021 code intermittently twice a month and then would go away. Never a check engine light. Now it started to feel like i lost a lot of power, and now i got the service engine soon light and the p0021 and p0524 codes were finally confirmed. I took off the vtc cover today does the ring look slipped?

Hard to see in this pic however the 2 teeth leg seems to be in a different position than the one I took a pic of when I did mine's. You'd need to confirm with other's on bank two to confirm. Most pictures I find are of bank 1

What two tooth leg are you talking about? On the phaser itself?

Hey bro, you ever figured out the issue? I have the exact same issue as you right now and can’t figure it out but my cam phaser looks just like yours.
