996 Cam deviation wanders after revving P0011


Recommended Posts

Hi,

 

I have a bit of an odd problem. I’ve owned my 2002 carrera for 18 months, and for all that time it’s had a P0011 code. When at idle cam deviation is 0, but as soon as I touch the throttle, it gradually climbs to around -11. I’ve changed the actuator, cam sensor and it’s just had the cam adjustor changed & an oil change, but it’s still there. 
when I changed the sensor it got slightly better (-13 down to -11). Car runs fine, no CEL. I’m using Durametric. 
IMS was changed when engine was rebuilt 2 years ago. 
any ideas?

Thanks for your reply. At idle the deviation is 0. It’s only once the engine is revved that it starts to climb. I’m 99% sure everything mechanically is ok as it’s just had the new cam adjuster & the timing checked. I’m thinking it’s more of an electrical issue. One other thing I thought of is, should there be a filter / screen on the variocam solenoid? There wasn’t one when I replaced it.
