This TSB has been revised to add a procedure to index the oil pump / balance shaft sprocket. Not properly indexing the sprocket may cause an engine vibration, mostly noticed at 3500-4000 rpm. The warranty information table has also been changed.
- Rough running.
- Rough idle.
- Lack of power at low rpm.
- Check engine light on (DTC P0335 crankshaft position sensor malfunction).
This condition may be caused by the exhaust camshaft coming out of time.
Vehicles that experience the condition described above should be updated with the new timing belt cover
