VVT Solenoid and Cam Sensors correlation P0016
Need help please with Camshaft/Crankshaft correlation issue with audi 2011 Q5 2.0TFSI.
Got code P0016 (Bank 1 Sensor A). checked both sensors they are good (replaced with new ones did not help - confirmation of sensors intact).
Noticed oil leakage residues at the VVT Magnet Valve and below is what I did:
1. Removed the VVT control magnet control valve. the pin got little stuck at first but cleaned and then it moves freely.
2. Measure the voltage of the plug coming to it: measures VDC 7.6V, The coil resistance of the valve is 6.7 ohm.
3. Tested the magnet control valve with a 9VDC battery and the pin pops fine. But when plug it back to the car it does not respond although the power from the plug has voltage. I also clean the pin connectors of both the valve and the plug, no help.)
4. the Solenoid itself looks fine and it move in when pushed with finger and springs back out freely.
Any idea what the issue can be and any suggestions what I should try next?
Thank you in advance.
