DTC Fault Trigger Conditions

DTC Description Fault Trigger Condition
PCM P0234:00 Turbocharger/Supercharger 'A' Overboost Condition: No Sub Type Information This DTC sets when the turbocharger system TCBP PID value is greater than a calibrated threshold, or the turbocharger system TCBP PID value is greater than the turbocharger boost pressure (TCBP) desired value for a calibrated length of time. Check tubing for restrictions, cracks and incorrect fitting connections. Check the turbocharger wastegate regulating valve solenoid for correct operation.
PCM P0245:00 Turbocharger/Supercharger Wastegate Actuator 'A' Low: No Sub Type Information Sets when the PCM detects an open circuit or a short to ground from the TCWRVS circuit. This DTC only sets when the solenoid valve is energized.
PCM P0246:00 Turbocharger/Supercharger Wastegate Actuator 'A' High: No Sub Type Information Sets when the PCM detects high voltage from the TCWRVS circuit. This DTC only sets when the solenoid valve is energized.
PCM P0299:00 Turbocharger/Supercharger 'A' Underboost Condition: No Sub Type Information Sets when the PCM detects the actual turbocharger boost pressure (TCBP) value is less than the desired turbocharger boost pressure (TCBP) value by 27.6 kPa (4 psi) or more for 5 seconds, indicating an under boost condition. Check tubing for restrictions, cracks and incorrect fitting connections. Check the turbocharger wastegate regulating valve solenoid for correct operation.
