앫 If the sector gear does not align with the
reference points, or does not rotate properly,
the turbocharger must be replaced.
앫 If the span check is satisfactory and an
actuation problem exists, the actuation

not require turbocharger replacement.
Review the Fault Codes and follow the
Actuator Troubleshooting Process in Guided
Diagnostics.

recommended grease evenly across all the
teeth on the sector gear.
