DTC P0045:00 [MZ-CD 1.6]

id0102g8145700

DTC P0045:00

Wastegate valve actuator control solenoid valve control circuit open
DETECTION CONDITION
•  The PCM monitors the load on the wastegate valve actuator control solenoid valve control circuit. If the load does not change for a continuous 0.5 s when the PCM duty-controls the wastegate valve actuator control solenoid valve, the PCM determines that there is an open circuit in the wastegate valve actuator control solenoid valve control circuit.
POSSIBLE CAUSE
•  Wastegate valve actuator control solenoid valve connector or terminal malfunction
•  Wastegate valve actuator control solenoid valve malfunction
•  PCM connector or terminal malfunction
•  Open circuit in the wiring harness between wastegate valve actuator control solenoid valve terminal A and PCM terminal 204
•  Open circuit in the wiring harness between wastegate valve actuator control solenoid valve terminal B and PCM terminal 229
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
•  Verify related service repair information availability.
•  Is any related repair information available?
Yes
Perform repair or diagnosis according to the available repair information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY RELATED PENDING CODE AND/OR DTC
•  Switch the ignition to ON (engine off).
•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
•  Is the other PENDING CODE/DTC also present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZ-CD 1.6].)
No
Go to the next step.
4
INSPECT WASTEGATE VALVE ACTUATOR CONTROL SOLENOID VALVE CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the wastegate valve actuator control solenoid valve connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 8.
No
Go to the next step.
5
INSPECT WASTEGATE VALVE ACTUATOR CONTROL SOLENOID VALVE
•  Inspect the wastegate valve actuator control solenoid valve.
•  Is there any malfunction?
Yes
Replace the wastegate valve actuator control solenoid valve, then go to Step 8.
No
Go to the next step.
6
INSPECT PCM CONNECTOR CONDITION
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Is there any malfunction?
Yes
Repair or replace the connector and/or terminals, then go to Step 8.
No
Go to the next step.
7
INSPECT WASTEGATE VALVE ACTUATOR CONTROL SOLENOID VALVE CONTROL CIRCUIT FOR OPEN CIRCUIT
•  Wastegate valve actuator control solenoid valve and PCM connectors are disconnected.
•  Inspect for continuity between wastegate valve actuator control solenoid valve terminal A (wiring harness-side) and PCM terminal 204 (wiring harness-side).
•  Inspect for continuity between wastegate valve actuator control solenoid valve terminal B (wiring harness-side) and PCM terminal 229 (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to the next step.
8
VERIFY THAT DTC P0045:00 TROUBLESHOOTING IS COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Run the vehicle under the FREEZE FRAME DATA stored condition.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
9
VERIFY AFTER REPAIR PROCEDURE
•  Perform the after repair procedure.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZ-CD 1.6].)
No
DTC troubleshooting completed.
