VVT fix or delete with normal cam?

[LanceD]

I'm having problems with the vvt I think on my 07 escalade. Code P0011. what parts could be bad? Should I start replacing vvt parts and hope they won't go bad again or just delete it all and put a decent cam in?

there was just a post a few weeks ago about someone replacing a few parts without having to tear to much into the engine :http://www.tahoeyukonforum.com/threads/p0011-code-and-plan-of-attack.100414/

where as cam swap is quite an undertaking, plan on spending about 1500 plus tuning, but enjoy the added performance and knowing the afm is all gone

Hmm. I searched and that thread didn't come up. Doesn't really help me with troubleshooting except that I need a tech 2. Can you command the vvt to move without buying a subscription?

That code Lance is for the CMP or Camshaft Position Actuator Solenoid. Old oil, additives in the oil, wrong viscosity, etc. can contribute to this code being thrown. Remember, you do not need a subscription to use your Tech2, only to program modules. You can hook up the Tech2 and command the actuator to 25 degrees and see if it can meet that. Did you sign up for the AllDataDIY subscription yet?

It would be less expensive and quicker in the short term to repair it.

I haven't but I'm doing it now

Why won't it let me do a 5 year subscription for my 11 Tahoe?

 

[swathdiver]

IDK, I've done yearly and 3 for the last 12 years on various cars. Probably cause they want to make more money for a subscription after three years to keep their wallets happy.

They sell a vvt phaser lock that supposed to give some more HP by locking the phaser in Place. I changed mine and it wasn't a fun job had to remove a bunch of stuff.

Looks like it's definitely broke. Got my Tech 2 in the mail today and this is what I found.

So the magnet that actual changes the cam timing is bad? Wonder if that's my issue too...o don't have a fancy device to test thou lol

It's gotta be that or the solenoid itself I would think.

Let me know what you fix and how it goes.

 

[LanceD]

I got HP tuners today and the first thing I did was disable the VVT and set the a/c to turn off above 60% throttle. Took it for a test ride and no check engine light. Eventually I'll get to fixing the root problem by putting a different cam in.

 

[swathdiver]

Let us know if you notice a slight decrease in highway mileage and full throttle power (probably slight enough to only be measured at track or dyno).

Ohh, just the saw the older post where you got hold of a Tech2, great! Now you can do almost anything with both systems!

 

[sfc_jones]

If you want to delete the AFM, Install LS7 Lifters and a LS7 Cam. Call Texas Speed, They have a complete kit for almost a 1k and they can also do delete tune as well. I chose to have mine tuned on a dyno. Luckily my son works at a performance shop so I got free labor.

 

[Denali2k8]

Any update since you turned off the VVT?

 

[Bucky1]

How is the HP tuner? I assume that that gives a great deal of freedom with the tuning. Are there resources to help with tuning guidance?

What is the biggest drawback with the VVT?

 

[LanceD]

HP tuners is great, practically unlimited with what you can do. There are tons of tutorials and training resources for it. I’d hold off on getting the new model until they work out the kinks.
As for the VVT it provides a flatter torque curve and I left it turned on for now until the cam swap.
The DOD has been disabled for a while now and I haven’t noticed a difference in fuel mileage.

i think people get vvt and afm mixed up. I don't think you can just turn off vvt. there other things that have to be done. there really isn't a drawback to vvt. its the best of both worlds. I wouldn't get rid of it unless you are planning on going FI. other than that I would keep it, and that includes cam swap. texas speed makes several vvt cams and they actually do a better job. here is a vvt delete kit https://www.texas-speed.com/p-724-vvt-delete-kit.aspx
afm (active fuel management) is what everyone wants to turn off. that's what make your vehicle go into 4cy mode.
