So I did a oil change with the correct factory oil recommended and filter. Oil level is good afterwards, then I started to get a oil light flickering when engine is stalled. Vsa and engine light are both still on. Anyhow p2647 read
A rocker arm actuator system stuck on bank 1
Oil pressure switch (a) circuit high voltage..

So I'm looking at changing out solenoid, oil sensor and gaskets. I'll attach a photo and was wondering if you can help me identify if this is the exact location of both sensor and solenoid. I couldn't seem to find any other sensor or solenoid in the engine. And bank 1 is closest to firewall. anyways some advice will be helpful before I order parts..

Thank you.

I attached the location of the pressure sensor and the rocker arm sensor location as well.

I would consider having the oil system pressure flushed with hot acid to break up all the dirt and debris. That is the main cause for this issue.

1. Disconnect the oil pressure switch connector, then remove the oil pressure switch.

2. '07 model J35A6, J35A7 engines: Remove any old liquid gasket from the switch and switch mounting hole.
3. '07 model J35A6, J35A7 engines: Apply liquid gasket to the new oil pressure switch threads, then install the oil pressure switch.

NOTE: Using too much liquid gasket may cause liquid gasket to enter oil passage or the end of the new oil pressure switch.

4. '08 model J35A6 engine: Install the oil pressure switch with a new O-ring.
5. Connect the oil pressure switch connector.

Rocker Arm Oil Pressure Sensor Replacement

Correct.

Your picture has the sensor location correctly. The green is the oil pressure sensor.
