Intake Valve Timing Control Position Sensor
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 camshaft sprocket con-
cave (in three 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.
CONSULT-II Reference Value in Data Monitor ModeNBS0042P
Specification data are reference values.
On Board Diagnosis LogicNBS0042Q
