Celica Forums Install Guides and Technical Articles Engine and Transmission Guides VVTI Fluid Control Valve Filter (GTS) - How To Clean

By Mike Walker

1st off this is for the GTS people ONLY

Symptoms: If you have problems of losing lift or Lift kicking on late (I.E.- 6500 rpms instead of 6200 rpms) and your lift bolts are NOT broken you'll want to check this filter.

Cause: Small particulates can get stuck inside the metal mesh filter which adds more resistance to the path of the oil. This means the oil take slonger to travel and results in lift coming on late or in severe cases not at all.

hope this helps. Lemme know if you have questions or problems

wow thanks so much lucky im going outside to do this right now, thanks

super i finish in like 30 mins great job lucky

maybe it is only for GTS but I was on TRD's website looking at an install for the supercharger... and they have this in the install

The GT won't have the problems a GTS has. Both cars have VVTI but a GT doesnt have lift

I also found that this can sometimes cuase a P1692 code. so cleaning it in some cases will clear this code.
