DTC Code | DTC Name |
---|---|
P0045 | Turbocharger / Supercharger Boost Control "A" Circuit / Open |
DESCRIPTION
Turbo pressure is controlled through the use of variable turbine geometry equipped to the turbocharger. Adjustable guide vanes are installed to the outside of the turbine wheel on the exhaust side.
A DC motor is used to drive and change the angle of the guide vanes. This adjusts the amount of exhaust gas added to the turbine and changes the drive torque of the turbine wheel. As a result, the boost pressure is adjusted as needed.
DTC No. | DTC Detection Condition | Trouble Area |
---|---|---|
P0045 | Open in DC motor (turbocharger sub-assembly) circuit for 0.22 seconds. (1 trip detection logic) |

Note
When replacing the ECM, the ECM needs Registration and Initialization Click here.
Tech Tips
When the ECM must be replaced, before replacing the ECM, perform the "Learning Values Save" function using the GTS. Then after installing the new ECM, perform all of the initialization/registrations for the "Learning Values Write" function by following the instructions shown on the GTS display.
Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.
PROCEDURE
CHECK HARNESS AND CONNECTOR (DC MOTOR - ECM)
