Likely Causes
  1. Dirty or low engine oil causing variable valve timing malfunction
  2. Failed intake camshaft position actuator solenoid
  3. Clogged oil passages to the cam phaser
  4. Worn or stretched timing chain
  5. Faulty camshaft position sensor providing incorrect timing data
How to Fix It
1
Check engine oil level and quality; replace if dirty or wrong viscosity
2
Inspect the intake cam actuator solenoid screen/filter for debris
3
Test the intake camshaft actuator solenoid for proper resistance and operation
4
Use a scan tool to monitor camshaft position timing values at idle and under load
5
If solenoid and oil are good, inspect timing chain for stretch and cam phaser for wear
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
