SP 255-022, Engine VGT Actuator and TSS Sensor
Connector Relocation
(June 2012)
A new campaign is available to prevent engine diagnostic trouble codes (DTCs) and missing
signal from the Engine Variable Geometry Turbocharger Actuator (Engine VGT Actuator) on
VOLVO D13 US2010 engines with a Mechanical transmission. This condition is caused by
fretting of the connector pins in the engine VGT actuator connector. Relocation of the engine
VGT actuator connector and a new mounting arrangement has been developed to eliminate
this condition. See the table below for the list of parts required for this campaign.
