DTC P1140, P1145 IVT CONTROL POSITION SENSORComponent Description
Intake valve timing control position sensors are located in the front of cylinder heads in both bank 1 and bank 2.
This sensor uses a Hall IC.
The cam position is determined by the intake primary cam sprocket concave (in four places). The ECM provides feedback to the intake valve timing control for appropriate target valve open-close timing according to drive conditions based on detected cam position.
