Overview: Code Cause Effect on Vehicle Fault Code: P0246-00 1. Open in the control circuit (ground circuit) between the VGT /boost pressure control solenoid A and the PCM 2. Open in the power supply circuit between the VGT /boost pressure control solenoid A and the PCM 3. Short to ground in the power supply circuit to the VGT /boost pressure control solenoid A 4. VGT /boost pressure control solenoid A faulty 5. Possibly a PCM has failed (highly unlikely) 1.Malfunction Indicator Light On 2.Instrument cluster message alerting driver to condition 3.Lack of power Trouble Shooting Steps: Sr. No. Steps Specifications Step 1 Check connector is connected properly Remove and connect again Step 2 Check for any open circuit between ECU and waste-gate control solenoid A Check the continuity Step 3 Check for any short to ground in the power supply circuit to the waste-gate/boost pressure control solenoid A Connect the ECU connector properly Step 4 Check ECU Physical/ Electrical check
