CONDITION
Some customers may comment that the Malfunction Indicator Lamp (MIL) light is on
and vehicle is in reduced power mode.
CAUSE
The Variable Nozzle Turbocharger (VNT) Control Unit (Module) may have detected a
false nozzle position error and set DTC P0045. The setting criteria for DTC P0045 were
too strict. As a result, the control unit may detect a false nozzle position and set this
DTC.
CORRECTION
Refer to the Service Manual and follow the diagnostic procedure. If no other system
faults can be identified, replace the Turbocharger Control Unit (Module).
