Hello! I am having a P1354 Code on my 1999 ES300... It is also pulling misfire codes all cylinders on Bank 2 (2,4, and 6) My first thought was engine sludge (265,000miles on the car) so I pulled off the valve cover and no sludge... SO next I thought its probably the bank 2 OCV... I pulled out both valves... I took a 9v battery and they both click open and closed when I touch the leads with the wires from the 9v... Does this mean that the valves are both ok? I'm hoping its not the ECU but its looking more and more like thats what it is... Thank you a TON for any help!!!

 

I had the same exact issue. I just replaced the OCV {OIL CONTROL VALVE** It worked for me.
I tried to circle where its located. I'm not sure where the 2nd one is.
I got the part 15340-20010 for VVTI for about $60.
