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 primary cam sprocket
concave (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 ModeNBS005BA
Specification data are reference values.
On Board Diagnosis LogicNBS005BB
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode.
