996 Cam deviation wanders after revving P0011

[Pk996]

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?

P0011 Position of Camshaft in Relation to Crankshaft, Bank 1 – Below Limit 

Diagnosis conditions
• Idle speed
• Reference mark recognized
• Engine speed between 600 rpm and 1200 rpm.
• Engine temperature greater than 40 °C
• No fault in camshaft position sensors
• Reference mark OK
• No fault in camshaft adjustment
• No fault in engine temperature
• No fault in camshaft adjustment output stage

Possible fault cause
◆ Allocation of camshaft to inlet camshaft incorrect
Affected terminals

Diagnosis/Troubleshooting
Note!
• This fault is stored if the engine was disassembled and the allocation of the camshaft to the inlet camshaft was incorrectly set.

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.
