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.
DESCRIPTION:
Some 2001 MY 2.4L Sonata and Santa Fe vehicles may experience one or more of the following conditions:
1.
Rough running.
2.
Rough Idle.
3.
Lack of power at low rpm.
4.
Check engine light on (DTC P0335 crankshaft position sensor malfunction).
This condition may be caused by the exhaust camshaft coming out of time.
A new timing belt cover P/N 21360-38214-D that incorporates a timing belt guide has been installed on vehicles produced since January 30, 2001.
Vehicles that experience the condition described above should be updated with the new timing belt cover
INSPECTION:
1.
Inspect the production date of the vehicle. Vehicles produced on or after January 30, 2001 are not affected by this TSB.
2.
Remove the upper timing belt cover
3.
Rotate the crankshaft until the timing mark of the intake cam sprocket is aligned with the timing mark on the rocker cover.
4.
Inspect the alignment of the timing mark on the exhaust cam sprocket with the timing mark on the rocker cover:
a.
If the exhaust timing mark is properly timed, skip to step 13.
b.
If the exhaust timing mark is NOT TIMED properly, continue to the service procedure section.
