Assembly, Variable Valve Actuation: Inspection
WARNING: This page is about a different variant/trim than selected.
Because variable valve actuation is so closely monitored, the diagnostics of the system are strongly Diagnostic Trouble Code (DTC) driven. If the system does not perform according to design, many DTC's may be produced from a condition in the variable valve actuation system.
The variable valve actuation module includes very few serviceable components. The module has no internal components that are serviceable. The following components are serviceable:
- Valve rocker arms (1)
- Oil supply O-ring (2)
- Oil temperature sensor (3)
