I have had my 2003 GT 2zz ge for a little bit now and when I first got it lift would work but now when I try to go into lift nothing happens and at 7000 rpm the engine light comes on brining up code p1693, I replaced the ocv on the drivers side and it worked for a bit but now it doesn't work at all and the same code is coming up. Any ideas?!?! 156000KM (97500 miles)
and check the link inside the above post. You did clean the strainer when you changed out the valve? You need to check the strainer again and check your wiring and connections to the valve.
