camshaft magnetic adjuster on 3.2

can someone explain to me how the camshaft adjuster solenoid works into relation the magnet or nut looking spring loaded nut under this sensor . my guess it used voltage on the adjuster to slow this nut armature to adjust the cam counter gear ?? I keep getting code P0341 and I was told to replace the armature and roll pin ... I checked the resistance on the adjuster it was at 5.0 ohms cold , so I am guessing the windings are ok ??
This code comes back immediately when the car starts... and yes the car is in limo mode , because its sluggish and hesitates a little ... thanks in advance

Sluggish is normal in limo mode!!! Limos are much heavier than normal cars.

Give us some more info on the car! 3,2 can be anything from a inline 6cyl diesel engine to a V6 petrol engine.

The engine starts with the cam retarded. As soon as oil pressure is established it pushes the cam into the advanced position. When the solenoid is energized it pulls a plunger that releases the oil pressure going to the advancer mechanism allowing the cam to retard for higher RPM operation.

If it is throwing a fault immediately after starting, I'd suspect a problem in how the ECU recognizes cam position, and not necessarily the function of the advance / retard mechanism. That said I dont recall the exact text of that fault code so dont hold me to it.

Applying power to the solenoid with the engine idling should make the idle quality noticeably worse if the cam is actually retarding properly. That is the first test I'd perform.

I believe its how the ecu is seeing the cam position ,, can some one tell me how to verify the camshaft is set up correctly . I know someone was in the timing chain area I see the evidence .... thanks
