DTC P0245 | Turbocharger wastegate solenoid low
--- | ---
DETECTION CONDITION | • When the PCM turns the wastegate control solenoid valve off but the wastegate control solenoid valve circuit voltage is low, the PCM determines that the wastegate control solenoid valve control circuit voltage is low. Diagnostic support note • This is a continuous monitor (Other). • The MIL does not illuminate. • PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle. • FREEZE FRAME DATA is not available. • DTCs are stored in the PCM memory.
POSSIBLE CAUSE | • Wastegate control solenoid valve malfunction • Connector or terminal malfunction • Open circuit in the wiring harness between wastegate control solenoid valve terminal A and main relay • Open circuit in the wiring harness between wastegate control solenoid valve terminal B and PCM terminal 4H • Short to ground in the wiring harness between wastegate control solenoid valve terminal B and PCM terminal 4H • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has 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 Information availability. • Is any related Service Information available? | Yes | Perform repair or diagnosis according to the available Service information. If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | INSPECT WASTEGATE CONTROL SOLENOID VALVE CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the wastegate control solenoid valve connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 8.
No | Go to the next step.
4 | INSPECT WASTEGATE CONTROL SOLENOID VALVE CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Inspect for continuity between the wastegate control solenoid valve terminal B and body ground. • Is there continuity? | Yes | Repair or replace the wiring harness for a possible short to ground, then go to Step 8.
No | Go to the next step.
5 | INSPECT WASTEGATE CONTROL SOLENOID VALVE • Inspect the wastegate control solenoid valve. (See WASTEGATE CONTROL SOLENOID VALVE INSPECTION [L3 Turbo].) • Is there any malfunction? | Yes | Replace the wastegate control solenoid valve, then go to Step 8. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L3 Turbo].)
No | Go to the next step.
6 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 8.
No | Go to the next step.
7 | INSPECT WASTEGATE CONTROL SOLENOID VALVE GROUND CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect for continuity between the following terminals: - Wastegate control solenoid valve terminal A (wiring harness-side) and main relay - Wastegate control solenoid valve terminal B (wiring harness-side) and PCM terminal 4H (wiring harness-side) • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for an open circuit, then go to the next step.
8 | VERIFY TROUBLESHOOTING OF DTC P0245 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)
No | Go to the next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [L3 Turbo].) • Are any DTCs present? | Yes | Go to the applicable DTC troubleshooting. (See DTC TABLE [L3 Turbo].)
No | DTC troubleshooting completed.
