2010 Nissan Maxima Loosing power while hard acceleration

for the 021 code check the one chart with arrows. for the 197 code check engine oil temp sensor for resistance if ok put some dielectric grease on connector and see if that cures it . pics
if not that it may be a sensor/solenoid/connection or shorted wire.

thanks
but i don't understand
accumulation of debris

can u please explain this

you have to take the sensor out and se if there is pieces of oil sludge and such on cam

ok thanks
i ordered the solenoid
let see tomorrow

can u please give me the exact location of the valve ( bank 2 )

and sir please give the location of oil temperature sensor also

thanks a lot

see pics they aren't very good but that is all we have

hi sir
back again

i changed the VTC valve and the DTC P0021 disappeared

but fed up with P0197 engine oil temperature couldn't locate

may be its same as oil pressure ?????

see pic for oil temp sensor
