DTC P0045 Turbocharger / Supercharger Boost Control Solenoid Circuit / Open


DESCRIPTION

The ECM optimizes the balance between the back pressure and boost pressure so that the balance is most appropriate for the engine speed and load, by performing two functions. It signals the Vacuum Regulating Valve to open and close the variable nozzle vane that is built around the circumference of the turbine, and adjusts the flow rate and pressure of the exhaust gas that is input to the turbocharger.

INSPECTION PROCEDURE

УКАЗАНИЕ:
Read freeze frame data using an intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
1.INSPECT VACUUM REGULATING VALVE ASSEMBLY (OPERATION)

  1. Remove the vacuum regulating valve (See page Нажмите здесь).

  1. Apply 4 dry batteries of 1.5 V in series.

  1. Check that the needle does not move when a vacuum is applied to the vacuum inlet port.

    OK:
    The vacuum regulating valve operates normally.

  1. Reinstall the vacuum regulating valve (See page Нажмите здесь).
