2012 Odyssey EX-L. I replaced VVT solenoid gaskets bank 2 (front) (due to oil leaking on alternator and ruining it). Drove several miles > MIL came on (P3497 only) and running rough with loss of power. If I clear and reset codes > MIL comes on immediately (same P3497) and power loss continues. However, if I clear codes and engine is cool, then it runs fine and no MIL, UNTIL engine warms up (about 5-6 miles on interstate) and then MIL (P3497) and runs rough with loss of power again. I replaced the VVT oil pressure switch > no change. Do I need to replace the VVT solenoid to fix this? Is this just coincidence, or did I damage something when replacing those gaskets (simple, easy procedure that was uneventful).
