P0234 - TURBOCHARGER/SUPERCHARGER A OVERBOOST CONDITION

For Ford GT
Description:	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 TCBP desired value for a calibrated length of time. This DTC may also set if the calculated turbocharger turbine speed is greater than a calibrated threshold, or the calculated turbocharger turbine speed difference between bank 1 and bank 2 is greater than a calibrated threshold.
Possible Causes:	Damaged wastegate adjusting rod Wastegate stuck closed Incorrect wastegate adjustment TC wastegate regulating solenoid valve stuck Damaged turbocharger (TC) wastegate regulating valve solenoid TC wastegate regulating solenoid valve stuck TC wastegate regulating solenoid valve control hose or vent leak or restriction Substantial restriction of bank 1 or bank 2 air filter, charge air cooler CAC, or CAC tubing
Diagnostic Aids:	Check tubing for restrictions, cracks and incorrect fitting connections. Check the turbocharger wastegate regulating valve solenoid for correct operation.
