Need Help Guys, VVT code after AutoJen vamshaft install
 

HI guys,
After install jun camshaft to 370Z I get check engine VVT code. Any idea why? Should I change it. Thanks Guys.

what code number was it? when you installed the cams did you do the vvel position sensor reset in the manual?

sorry the code is P1090

I dont know if they did the VVEL reset?

Well that is what they need to do it is described in the FSM, While they are at it have them check to make sure they plugged everything in but it is almost certainly a case of they didn't perform the reset procedure.

You plan on putting it on a dyno anytime soon? how many hours did it take to install?

Hi Elmo370Z,
Yes I will put it on dayno after a fix the Code P1090. And I will post the sheet to you guys. It took them couple of day because the shop is full. And I wanted a specific mechanics to work on my car.

Hi guys,
I have the cam installed and the code P1080 fixed. Now I have another problem. The car does not have power the RPM will not go up. Lose of power. Any Idea what to look at.

After changing the cam I believe the can need to be adjusted at specific degree , what is this degree and do we need sprocket kit for that ?

Any input guys

i think you may be getting very few responses because this is essentially uncharted water for 99.99% of the people on this forum. very little is known about cams in this car. has your mechanic every performed a 370 cam swap before?

I already explained what he has to do, you need to download the factory service manual, go to section ec, scroll down to cam removal replacement and follow the procedure to reset the vvel sensor on the backs of the heads, it is the big one held in by 2 bolts this needs to be done or the car will not know where the vvel shafts are positioned. you need a volt meter and a 10mm wrench.

OP, you asked for advice, this guy told you what to do (twice!). why dont you try this first? is your mechanic skilled enough to do the above?

I thought of another reason he may be having issues, if your mechanic didnt reset the valve lash after the cam install you may have valves that arent closing, get your motor compression tested if it fails, find a new mechanic.
